Questions about how the universe works are not always easy to answer. For many centuries most people (scientists and philosophers included) thought the earth was at its center and that the planets, moon, sun, and stars revolved around us. This is called “geocentrism” or the “geocentric view of the universe”. It took years of painstaking work, spread out over multiple centuries, to show that this was false as an absolute claim. Today, we accept a “geokinetic” (moving-earth) view based on the work of Newton and Einstein. For the student of history and/or science, how we came to the modern view is an amazing exploration of how things work and a testimony to the amazing ability to reason that God uniquely put into people.
We live in a created universe, meaning its existence did not come about through naturalistic processes alone. We also live in a well-ordered universe; meaning it behaves according to a set of rules. This is consistent with it being created by an ultimate Lawgiver, who is not fickle and acts in a consistent manner, according to His very nature
However, it is far more difficult to take these experiments and use them to explain the origin of everything. When a person tries to predict backwards to infinity, this type of science breaks down. Philosophically, there are paradoxes waiting around every corner. For example, we are either in a steady-state universe that defies the 2nd Law of Thermodynamics, or we are in a universe that has a beginning but without a cause. Scientifically, we see how appeals to big bang physics have led to much speculation, including inflation theory, dark matter, dark energy, the fine tuning of numerous constants in order to get the models pointing in the right direction, etc. Therefore, even after we have learned all this about the mechanics of the universe, once we begin trying to explain how it all began we get into the realm of faith. True, there are still puzzles to be explained in the “young-earth” position, but since evolutionists explain away their puzzles with ‘it’s science’s job to solve these puzzles’, the same allowances should be made for creationist scientists.
The question about whether or not earth is at the center is not as easy to answer as the “flat earth” question. Not only are these two ideas not the same, but no significant evidence exists for flat earth beliefs among scientists going back to the Greeks. Indeed, a Greek scientist named Eratosthenes of Cyrene (276–194 BC) calculated the circumference of the earth (to an amazing degree of accuracy). Within the circles of Christian scholarship, no notable theologian seems to have believed in a flat earth, not only because of it so obviously is not, but also because the Bible does not claim it is. Notable theologians throughout the Christian era believed the earth is spherical. Even in the midst of the falsely-named “Dark Ages”, the leading Anglo-Saxon scholar and monk ‘the Venerable’ Bede (AD673–735), one of most widely-read scholars for the next 1000 years, wrote that the earth:
… in its width it is like a circle, and not circular like a shield but rather like a ball, and it extends from its centre with perfect roundness on all sides.1
The relationship between the spherical earth and the universe, however, was a notorious nut to crack, with many famous scientists weighing in on the difficulty. The main problem is that we are here on earth and, to us, it appears that everything revolves around our planet. We don’t feel like we are sailing through the heavens. We don’t feel like we are moving at all. Is it possible to sort out fact from fiction in this subject? Actually, yes. The answer is both elegant and satisfying, but we must do a little digging to answer the riddle.
Biblical phenomenological language
Well-meaning Christian geocentrists basically say, “The Bible says the sun rises and sets and that the earth doesn’t move; that settles it.” However, does the Bible really say that absolute geocentrism is true? The use of language complicates this subject. Even today, in both writing and in common speech, people often use “phenomenological language”. Indeed, it would be almost impossible to have many conversations if we did not talk about things like “sunrise” (go ahead, try to describe a sunrise or sunset without sounding like you are stationary and the sun is moving, and compare with our attempt below). Thus, even when consulting biblical passages, we must be wary of the use of language. This was recognized in the Middle Ages by scientist-clergy such as the priest Jean Buridan (c. 1300–c. 1360), the bishop Nicole Oresme (c. 1320–1382),2,3 and Cardinal Nicholas of Cusa (1401–1464).4 If you think these men are perhaps insignificant, Buridan’s formulation anticipated the principle of describing motion with respect to reference frames, which paved the way for Galileo, Newton, and Einstein. His idea of impetus anticipated Galileo’s concept of inertia and Newton’s First Law of Motion.5 Historian of science, James Hannam, comments:
Like many medieval Christians, Buridan expected God to have arranged things in an elegant way, always allowing that he could do as he pleased. However, although there was also a presumption towards elegance, you still had to check the empirical facts to see if God really operated this way.6
Dr Henry Richter, Dr Robert Carter, Dr Jonathan Sarfati, and CMI-US CEO Gary Bates discuss flat earth teaching and geocentrism.
Living almost exactly 100 years after Buridan, Nicholas of Cusa wrote eloquently on the subject:
It has already become evident to us that the earth is indeed moved, even though we do not perceive this to be the case. For we apprehend motion only through a certain comparison with something fixed. For example, if someone did not know that a body of water was flowing and did not see the shore while he was on a ship in the middle of the water, how would he recognize that the ship was being moved? And because of the fact that it would always seem to each person (whether he were on the earth, the sun, or another star) that he was at the “immovable” center, so to speak, and that all other things were moved: assuredly, it would always be the case that if he were on the sun, he would fix a set of poles in relation to himself; if on the earth, another set; on the moon, another; on Mars, another; and so on. Hence, the world-machine will have its center everywhere and its circumference nowhere, so to speak; for God, who is everywhere and nowhere, is its circumference and center.7
It is clear here that he believed the earth moved through space, and he clearly understood the principle of frames of reference (discussed in more detail below). Buridan and Nicolas predate the Copernican Revolution, meaning later scientists did not come up with their ideas on their own.8 Centuries of scholarship had been working in this direction.
When we consider the biblical ‘proof texts’, most are taken out of context by those few people who want to argue for absolute geocentrism (the view that the earth is fixed and does not rotate while everything in the universe rotates about us once every day). This taking out of context is done both by biblioskeptics and, unfortunately, modern geocentrists who take their views as gospel.
There are multiple verses that have a generic reference to “sunrise”, including Genesis 19:23, Exodus 22:3, Judges 5:31, Judges 9:33, Job 9:7, Psalm 104:22, Ecclesiastes 1:5, Nahum 3:17, Matthew 5:45, Mark 16:2, and James 1:11. There are also a number of verses that use “sunrise” in relation to the direction “east”, which makes perfect sense, including Numbers 2:3, Numbers 3:38, Numbers 34:15, Joshua 1:15, Joshua 12:1, Joshua 13:5, Joshua 19:12, and Joshua 19:13. Indeed, the normal Greek word for ‘east’, ἀνατολή (anatolē, e.g. Matthew 2:1), has the primary meaning of ‘rising’, usually of the sun. In other places, “sunrise” is used in a prophetic or poetic sense, including Luke 1:78 (also anatolē), which comes in the middle of the prophesy of Zechariah, father of John the Baptist, and is comparing Christ to the sunrise “that shall visit us from on high”. This is similar to the prophesy of Malachi 4:2 that claims “the sun of righteousness shall rise with healing in its wings.” Additional references can be found in Psalm 50:1 (“The Mighty One, God the Lord, speaks and summons the earth from the rising of the sun to its setting.”), Malachi 1:11 (“For from the rising of the sun to its setting my name will be great among the nations…”), and Psalm 113:3 (“From the rising of the sun to its setting, the name of the Lord is to be praised!”).
There are also multiple verses that have a reference to “sunset”, including Genesis 28:11, Deuteronomy 16:6, Deuteronomy 23:11, Deuteronomy 24:13, Deuteronomy 24:15, Joshua 8:29, Joshua 10:27, 1 Kings 22:36, 2 Chronicles 18:34, Psalm 50:1, Psalm 104:19, Psalm 113:3, Ecclesiastes 1:5, Daniel 6:14, Malachi 1:11, and Luke 4:40.
None of these verses is a challenge to geokinetic theory and none actually support geocentrism for all are acceptable uses of phenomenological language and, as mentioned earlier, we use similar phrases every day with no intention of misleading anyone into thinking we are geocentrists. Modern geokinetic astronomers teach using a planetarium, which treats the earth as the center of an infinite celestial sphere, and is full of phenomenological ‘geocentric’ terms such zenith, nadir, celestial poles and equator. Language conventions like this are necessary for simple communication.
There are other passages, however, that require a more careful exegesis. After the Israelites crossed the Jordan into Canaan, they defeated the cities of Jericho and Ai (Joshua 1–8). Soon after that the residents of Gibeon tricked Israel to entering into a covenant with them (Joshua 9). Gibeon was to the west of Ai and an obvious next target for the invading army. The other peoples in the area were angry and went to war against the Gibeonites. Israel came to their aid and a great battle was fought (Joshua 10). In the midst of this battle, the Bible says:
At that time Joshua spoke to the Lord in the day when the Lord gave the Amorites over to the sons of Israel, and he said in the sight of Israel, “Sun, stand still at Gibeon, and moon, in the Valley of Aijalon.” And the sun stood still, and the moon stopped, until the nation took vengeance on their enemies. Is this not written in the Book of Jashar? The sun stopped in the midst of heaven and did not hurry to set for about a whole day. There has been no day like it before or since, when the Lord heeded the voice of a man, for the Lord fought for Israel.
This very famous passage describes Joshua’s Long Day, and is often used to support geocentric views, but what is it saying, really? Obviously, the statements are being given in a local frame of reference. Why? Because the sun standing over Gibeon would not appear to be overhead anywhere except in the geographic vicinity of Gibeon. The valley of Aijalon is to the west of Gibeon. Therefore, the moon would not appear to be to the west of Gibeon to someone standing in Aijalon; it would be out over the Mediterranean.9 Many claim this passage teaches that God stopped the moving sun and moon. Yet there is nothing here to say that he did not temporarily slow down a rotating earth (as well as the hydrosphere and atmosphere). This would produce the same effect. Or He could have stopped the movement of everything in the universe. Same result. That something universal really happened in history is shown by legends of a long night in people groups on the other side of the globe.10
Note that the mention of the moon is a mark of authenticity. The Amorites were sun worshippers, so it makes sense for God to show His power over the false god. But if His means really was slowing down the earth, as we suggest, then this would also affect the relative motion of the moon, which otherwise need not have been mentioned.
And let us not forget the reversing of the course of the sun in the time of Hezekiah (2 Kings 20:5–11, Isaiah 38:1–7), an event that was noticed, or at least enquired about, by astronomers outside of Jerusalem (2 Chronicles 32:24–31). These deviations from the scientific norm are what allow us to identify miracles when they occur. In a geocentric universe, everything is one giant miracle with no simple explanation (see below). Certainly, a geocentrist would not expect the sun to stop or to move backward, but why not? There is no rational explanation for the way the universe operates, so why could something out of the ordinary not happen?
Psalm 96:10 is another critical verse for us to understand. It says:
Say among the nations, “The Lord reigns! Yes, the world is established; it shall never be moved; he will judge the peoples with equity.”
Similar statements that “the earth shall not be moved” appear in Psalm 93:1 and Psalm 104:5. Do these verses not say that the earth does not move? No, they do not, for one very simple reason: the Hebrew word מוֺט (mot) means “to totter, shake, or slip”11 and is often translated such in other places. The opposite of “shake” can be “unmoving”, as in these verses, but it can also be accurately translated “unshaken”. Using the same word, Psalm 55:22 and Psalm 112:6 say the righteous will never be moved. Same word, similar context, but obviously this does not mean people are fixed in place! Yet, if the righteous can move, so can the earth. Following on that theme, Psalm 121 is titled, “The Righteous shall never be moved.” verse 3 says God will never let your foot be moved, yet a few verses later talks about “coming in” and “going out”, meaning the feet must be moving and the earlier use of “shall not be moved” must be a metaphoric or poetic expression for “firm” or “unshaken”. Also, Psalm 16:8 says, “I shall not be moved,” and most biblioskeptics and geocentrists would not think that the Psalmist was in a strait jacket! Finally, Psalm 125:1 says those who trust in the Lord are like Mt. Zion, which cannot be moved and abides forever. This is perhaps a better place to use “cannot be moved”, for we are talking about a mountain, but even that will be burned up in the future (according to most views on eschatology), so the poetic expression is clear.
One other problem is the use of the word “firmament” in Genesis 1 in the King James version. That word comes straight out of the geocentric views of Ptolemy (AD 90–168) and his predecessors, albeit by a long route. Around 250 BC, Jewish scholars in Alexandria, Egypt, translated the Hebrew Bible into Greek to make the Septuagint LXX. Unfortunately, they imbibed some of the Greek cosmologies by translating the Hebrew word is רקיע (rāqîya‘) into steréōma (στερέωμα). This comes from the word στερεόω (stereoō)—“to make or be firm or solid.” We see this meaning carried over into Jerome’s Latin Vulgate, firmamentum. This was basically transliterated into the KJV’s “firmament”. Thus, this is an example where the science of the day influenced Bible translation, and vestiges remained for almost 2,000 years! [note: This is not a slam on the KJV necessarily. CMI does not take any particular stand on Bible translations, but this one word is demonstrably taken from the scientific views of the time.]
There is some debate among creationists on the meaning of rāqîya‘ in this context. Kulikovsky points out:
Note also that the semantic ranges of stereōma and firmamentum do not match rāqîya‘. The Hebrew word rāqîya‘ refers to something flexible or malleable which has been stretched out. As Livingston puts it: “The emphasis in the Hebrew word raqia is not on the material itself but on the act of spreading out or the condition of being expanded.” Stereōma and firmamentum, on the other hand, refer to something hard, solid and inflexible. Indeed, Seely admits that his historical etymology of rāqîya‘ and rāqa “does not absolutely prove that rāqîya‘ in Genesis 1 is solid.”15
J.P. Holding put it this way:
… the description of the raqiya‘ is so equivocal and lacking in detail that one can only read a solid sky into the text by assuming that it is there in the first place. One can, however, justifiably understand Genesis to be in harmony with what we presently know about the nature of the heavens.16
Thus, even though multiple interpretations could equally well fit, rāqîya‘ does not mean “solid dome”.
And as will be seen, most of the debate was about the science; or as philosopher of science Thomas Kuhn (1922–1996) put it, a shift in scientific paradigms.17,18 Most people in history spoke in geocentric terms, as most people do today—we say, “The sun is setting” not “The earth’s rotation is now bringing our line of sight to the sun into a tangent at my position on the earth’s surface.” But this does not mean that most of us today are geocentrists!
Thus, there is no real biblical problem with a geokinetic view. This is not the same argument as “is evolution true?” or “can we add millions of years of earth history to the Bible?” This is not using “science” to inform us about biblical theology, which all attempts at merging evolutionary time and the Bible end up doing. The nature of the relationship of the earth to the heavens is an open subject that begs for exploration. This is an example of the difference between the ministerial and magisterial uses of science. Geokineticism is ministerial in that is helps us to elucidate texts that could go either way. In contrast, long-age views of evolution are based on a magisterial abuse of science in order to override Scripture, with baneful theological consequences, like death before Adam’s sin.
Logic and science
This study is designed both to help Christians refute critics and to understand why geokinetism is both good science and biblically allowable.
Here’s the main logical problem with absolute geocentrism: it’s not that we could not construct a geocentric cosmology, as one of many allowable reference frames. It’s that there is no scientific or biblical reason why we would—there is no dynamic model to explain it, i.e. in terms of forces as efficient causes of motions. Therefore it has essentially no predictive value. Yes, it could describe planetary positions accurately enough for pre-telescope astronomy, admittedly a great achievement, but it fails to explain the orbital motions of satellites of other planets. It is useful in some respects, however, for launching things into orbit, for pointing earth-based antennae at geostationary satellites, for plotting the position of stars, etc. Yet, because it lacks predictive power, a fully-comprehensive geocentric model would be very, very complicated. They would need to add terms almost at random to account for the thousands of variations easily explained by geokineticism. There is another, perhaps stronger, point to make: geokinetics is the best way to understand the physics. The equations of motion are the simplest for the particles that orbit in a center-of-mass system and when the center is used as the origin in the co-ordinate frame. Science thrives on making predictions, and Newton’s three Laws of Motion and theory of gravity (with Einstein’s further refinements) are one of the most amazing predictive engines in history. Since Scripture doesn’t demand that a stationary earth is the only valid reference frame (absolute geocentrism), why would we hold to an earth-centered, earth-fixed reference frame?
Here’s the main scientific problem with geocentrism: if absolute geocentrism is true, then the laws of physics are not universal. That is, experiments we do on earth cannot apply to things outside the atmosphere because Newton’s laws of motion and gravity cannot explain what we are seeing. This is a big problem, for every time we do something in outer space everything behaves as if it would here on earth. Absolute geocentrism requires a universe that does not work according to Newton’s laws. Yes, you can attempt to describe the way things revolve around the earth in a absolute geocentric system, but gravity cannot be used to explain the motion of those objects; another force is required to glue the universe together. Where does the change occur? Certainly before we get to the moon, for that must orbit the earth once a day. But we cannot detect any such transition! We can fly a plane, launch a satellite, send things to the outer solar system and there is no place where Newtonian mechanics does not apply. For example, late in 2014, the Rosetta spacecraft from the European Space Agency successfully arrived at and orbited comet 67P/Churyumov–Gerasimenko. In a delicate and complex series of maneuvers, the craft deposited the Philae lander on the surface of the comet. Everything about that rendezvous is explained by Newtonian physics, and it is the same physics that works here on earth. If everything out there behaves as expected based on experiments here on earth, does this not mean that geokineticism is true and absolute geocentrism is not? If you can’t use gravity to explain the motion of objects in the solar system, you can’t use gravity to explain the motion of space probes flying among those objects. It is that simple.
Absolute geocentrism is then nothing more than ‘stamp collecting’. One cannot make many predictions. One can only describe what is seen. Essentially, they can describe observations without being able to explain those observations. The power of the geokinetic model lies in the fact that it is based on a simple observation that can then be used to explain multiple phenomena. The Achilles’ heel for those few who still believe the earth does not move is that their “model” is nothing more than a list of unrelated phenomena.
The main protagonist in the geocentrism debate is a man named Claudius Ptolemy (AD 90–168), a Greek scholar living in the Egyptian city of Alexandria in the second century AD. He had a profound influence on this debate, to the point that today the terms “geocentric” and “Ptolemaic” are interchangeable. Prior to him, however, there was no unanimity among Greek thinkers. In fact, several solar-centric views predated Ptolemy’s geocentrism. The Greek scholar Aristarchus of Samos (310–230 BC) is but one of those people. Interestingly, he also said that the sun must be further away than moon (because the moon can eclipse the sun). Since they have the same apparent size, he reasoned the size of the sun must be proportional to its distance behind the moon. He underestimated the size of the sun (and thus its distance) by a factor of 10, but his model was clearly heliocentric. And he was not the only ancient to struggle with it. The debate was known to famous people like Archimedes (287–212 BC), Seneca (4 BC – AD 45), Pliny the Elder (AD 23–79), and Plutarch (AD 45–120).
There were good reasons for most early people to believe in geocentrism and the scholars listed multiple evidences in support of it. Nicolaus Copernicus (1473–1543) summarized the arguments in Chapter 7 of his book On the Revolutions of the Celestial Spheres:19
Therefore, remarks Ptolemy of Alexandria (Syntaxis,20 1, 7), if the earth were to move, merely in a daily rotation, the opposite of what was said above would have to occur, since a motion would have to be exceedingly violent and its speed unsurpassable to carry the entire circumference of the earth around in twenty-four hours. But things which undergo an abrupt rotation seem utterly unsuited to gather (bodies to themselves), and seem more likely, if they have been produced by combination, to fly apart unless they are held together by some bond. The earth would long ago have burst asunder, he says, and dropped out of the skies (a quite preposterous notion); and, what is more, living creatures and any other loose weights would by no means remain unshaken. Nor would objects falling in a straight line descend perpendicularly to their appointed place, which would meantime have been withdrawn by so rapid a movement. Moreover, clouds and anything else floating in the air would be seen drifting always westward.
Copernicus uses the Aristotelian terminology of his opponents, where “violent” simply means “caused by an outside force”, and no one then knew Newton’s Second Law. For example, a book falling from a table is ‘natural motion’, while picking it up is ‘violent’ motion. Yet think about the implications of this Aristotelian view: if any outside force is ‘violent’, experimental science is invalid because any experimental manipulation cannot then be ‘natural’.
Some of the ancients tried to argue that, if the earth rotated, it would fly apart, people and animals would be flung from the surface, falling objects would curve as they fall to the surface, and there should be a perpetual east wind, as Copernicus explained. But he then takes the argument and turns it back on itself, issuing an even greater challenge in Chapter 8:
For these and similar reasons forsooth the ancients insist that the earth remains at rest in the middle of the universe, and that this is its status beyond any doubt. Yet if anyone believes that the earth rotates, surely he will hold that its motion is natural, not violent … Ptolemy has no cause, then, to fear that the earth and everything earthly will be disrupted by a rotation created through nature’s handiwork …
But why does he not feel this apprehension even more for the universe, whose motion must be the swifter, the bigger the heavens are than the earth? Or have the heavens become immense because the indescribable violence of their motion drives them away from the center? Would they also fall apart if they came to a halt? Were this reasoning sound, surely the size of the heavens would likewise grow to infinity. For the higher they are driven by the power of their motion, the faster that motion will be, since the circumference of which it must make the circuit in the period of twenty-four hours is constantly expanding; and, in turn, as the velocity of the motion mounts, the vastness of the heavens is enlarged. In this way the speed will increase the size, and the size the speed, to infinity. Yet according to the familiar axiom of physics that the infinite cannot be traversed or moved in any way, the heavens will therefore necessarily remain stationary.
As we will see, not only has ‘the earth will fly apart’ argument been answered, but so have the other arguments some of the ancients attempted to make.
The Church Fathers
The few Church Fathers who discussed the issue were geocentrists. However, it is not quite fair for modern geocentrists to quote the early Church Fathers in support. First, all the pagans of their day also supported geocentrism, so the Church Fathers just reflected common sense, common contemporary scientific ideas, or common use of language. They were hardly making a principled theological opposition to geokineticism.
Second, they were influenced by the faulty translation of the raqia’ in the available Greek and Latin translations. Third, their geocentrism was Ptolemaic Geocentrism, while modern geocentrists actually hold the Tychonian hybrid geo-heliocentrist view (see below). Since no Church Father held this modern view, how can one quote them in support?
Fourth, the first genuinely intellectual challenge to absolute geocentrism came from devout adherents to a broadly biblical world view.
The Middle Ages
Due to the work of leading lights like Boëthius (AD 480–525), who was following the lead in this case of Aristotle and Ptolemy (they were not wrong about everything, after all), scholars in the Middle Ages knew the earth was just a point compared to the vastness of space, saying:
As you have heard from the demonstrations of the astronomers, in comparison to the vastness of the heavens, it is agreed that the whole extent of the earth has the value of a mere point; that is to say, were the earth to be compared to the vastness of the heavenly sphere, it would be judged to have no volume at all.21
Yet most of them accepted the geocentric views of their day. Thomas Aquinas (1225–1274) had a great deal of influence in nearly fixing Aristotelian philosophy, and its cousin, Ptolemaic astronomy, in the minds of his contemporaries. However, after Aquinas, some clergy-scientists in the Middle Ages directly questioned Aristotelian philosophy. In fact, the Middle Ages saw the birth of the universities, where questioning authority was often encouraged.22 Because of the infinitesimally small size of the earth compared to the heavens, Buridan and Oresme proposed that it might be more elegant that the earth itself rotated rather than the cosmos revolving around it (following in the steps of several Greek philosophers who said the same). They answered most of the biblical and scientific objections that would be thrown at Galileo a few centuries later, but came short of asserting geokineticism as a fact, as Hannam explains:
What Oresme had done was prepare the groundwork. He refuted most of the objections to a moving earth two centuries before Copernicus had suggested that it might actually be in motion.23
A common thought in the Middle Ages was that the centre of the universe was the worst place to be. For example, Dante’s Divine Comedy (c. 1310) has nine circles of Hell inside the Earth, getting worse as they approach the center. Satan was right at the centre of a (spherical) earth, at the centre of the universe. In the opposite direction, the nine celestial spheres of heaven increased in virtue and closeness to God as they got further from the center. We certainly do not hold to Dante’s vision, but in this light moving the earth away from the center was a promotion in the eyes of people in the Middle Ages, not a demotion, as 21st century anachronistic skeptics claim.
Was heliocentrism the result of Hermetic paganism?
Some recent historians have tried to make the claim that Copernican theory was driven by some sort of Hermetic24 sun worship, but this is grossly anachronistic. By taking the ‘perfect’ sun and putting it at the center, instead of worshiping the sun, Copernicans were demoting it to the worst place.25And even though the Hermitica was widely read among the scholars of Copernicus’ time (the Renaissance), we do not believe Copernicus was among the adherents. Copernicus had one passing mention of Hermes among other ancient writings:
At rest, however, in the middle of everything is the sun. For in this most beautiful temple, who would place this lamp in another or better position than that from which it can light up the whole thing at the same time? For, the sun is not inappropriately called by some people the lantern of the universe, its mind by others, and its ruler by still others. (Hermes) the Thrice Greatest labels it a visible god, and Sophocles’ Electra, the all-seeing. Thus indeed, as though seated on a royal throne, the sun governs the family of planets revolving around it. Moreover, the earth is not deprived of the moon’s attendance. On the contrary, as Aristotle says in a work on animal, the moon has the closest kinship with the earth. Meanwhile the earth has intercourse with the sun, and is impregnated for its yearly parturition.
If this is a problem, then what about the Apostle Paul quoting pagan poets with approval: Aratus (Acts 17:28), Menander (1 Corinthians 15:33), and Epimenides (Titus 1:12)? Also, Copernicus had also cited Scripture with approval:
For would not the godly Psalmist (92:4) in vain declare that he was made glad through the work of the Lord and rejoiced in the works of His hands, were we not drawn to the contemplation of the highest good by this means, as though by a chariot?
Then see the alleged Hermetic heliocentrism:
Since it is the visual ray itself, the sun shines all around the cosmos with the utmost brilliance, on the part above and on the part below. For the sun is situated in the center of the cosmos, wearing it like a crown. Like a good driver, it steadies the chariot of the cosmos and fastens the reins to itself to prevent the cosmos going out of control. And the reins are these: life and soul and spirit and immortality and becoming. The driver slackens the reins to let the cosmos go, not far away (to tell the truth) but along with him. …
Around the sun are the eight spheres that depend from it: the sphere of the fixed stars, the six of the planets, and the one that surrounds the earth.
The above is hardly science at all, but mystical nonsense. So if any heliocentrist was influenced by Hermeticism, it was surely Giordano Bruno (1548–1600), a New-Agey non-scientist beloved of atheist Neil deGrasse Tyson.
Furthermore, this passage talks about a sphere surrounding the earth, and only the other planets surrounding the sun. Thus Hermeticism is also probably even more compatible with the Tychonian geo-heliocentrism hybrid beloved of modern geocentrists (see below). They would undoubtedly take umbrage if they were accused of being Hermeticists, so they should practise “do unto others” when it comes to accusing geokineticists.
A final point: geokineticism does not fall even if Copernicus was a rabid hermeticist (this would be the genetic fallacy), and in any case, this objection can’t touch Copernicus’ medieval predecessors or most other geokineticists. What we have to do is assess the evidence for and against absolute geocentrism and not resort to ad hominem distractions.
Did the Church suppress geokinetic theory?
Others have argued that the “Church” suppressed scientific advance by persecuting those who argued against absolute geocentrism, but history paints a very different picture. The Catholic Church, instead of being opposed to astronomy, spent tremendous amounts of money on it. Why? Because once the “Church” covered a significant portion of the globe, the calculation of the date of Easter became problematic. “The first Sunday after the first full moon after the vernal equinox” (Council of Nicea, AD 325) sounds like a precise formula, but it was entirely probable that different observers, even without making a mistake, could celebrate Easter on different days in different parts of the world. Add to that the fact that the Julian calendar was causing the calendar year to get farther and farther from the solar year (10 days off by the 1500s) and they had a real problem. To resolve these issues, cathedrals were enlisted as giant pinhole cameras projecting onto meridian lines (meridiane, singular meridiana). Thus the sun’s path through the sky could be accurately recorded, as documented by science historian John Heilbron (b. 1934).26 The cathedrals were ideal because they were huge, works of architectural genius, and were old enough for the foundations to have stabilized, so the positions of the meridiane would not shift. They were even more accurate astronomical instruments than the best telescopes of the day; telescopes did not surpass the meridiane until the mid-18th century.

The result of this work was the adoption of the Gregorian calendar in 1582, which we still use today. The calendar change occurred 50 years before the trial of Galileo and was “based on computations that made use of Copernicus’ work”, as Kuhn pointed out.27 So already the new astronomy of Copernicus had shown its practical superiority, also showing that the Church permitted this view as a working mathematical hypothesis.
After that, the work was refined even further. Interestingly, by 1655 (13 years after Galileo’s death) observations made in the Cathedral of Bologna by Giovanni Cassini (1625–1712) answered a great debate of the time, and gave concrete evidence that Kepler’s theory was correct and that Ptolemy’s was not. He also showed that the distance to the sun changed over time, meaning circular orbits were out of the question, so Kepler was right about elliptical orbits.28
Timeline of events—a fun romp through history
There are many names that enter into the story. Too many, in fact, to do justice to them all. Yet, it is good to put several of the more important names in a proper historical perspective. When the subject comes up, most people immediately think of Galileo and his trials, but he was actually not the first nor the most important figure. Nicolaus Copernicus (“the man who stopped the sun and moved the earth”29) died more than two decades before Galileo was even born, and Galileo’s censure did not occur until he was 70 years old.

The quest to solve this mystery was pushed by people with a Christian worldview who more or less believed the Bible. They saw no conflict between science and faith. Even the great astronomer Johannes Kepler said of his work that it was “like thinking God’s thoughts after him”, and:
The chief aim of all investigations of the external world should be to discover the rational order and harmony which has been imposed on it by God and which He revealed to us in the language of mathematics.30
But there was resistance to geokinetic ideas. This was mainly led by other scientists, not the “Church”. The views of Copernicus were known to the Pope and many bishops of the day, and they supported him. This is not to say that his views were not controversial, but that neither the Protestant nor Catholic churches summarily rejected geokineticism. Later, Galileo was encouraged in his work by Pope Urban VIII at first a close friend, but they later became bitter enemies after Galileo insulted him by putting the Pope’s words in the mouth of Simplicio (the fool) in a book that argued against geocentrism.31 Only a few decades after the death of Galileo and Urban VII, Jesuit astronomers were teaching geokineticism to astronomers in China. Georgio de Santillana (1902–1974), philosopher/historian of science at MIT, wrote:
It has been known for a long time that a major part of the church’s intellectuals were on the side of Galileo, while the clearest opposition to him came from secular ideas.32
Considering that the argument had been going on for centuries, it should not be surprising that there was a controversy among the scholars. Some of this came though the Protestant/Catholic divide, some of it came through hard-headedness of various people, and much of it has been manufactured by 19th-century anti-Christian polemicists.33,34
Perhaps the most important name in our brief tour of history is Nicolaus Copernicus. Copernicus was not only an astronomer but also a linguist, classical scholar, physician, doctor in canon law of the church, and an insightful economist.35 Although his geokinetic ideas were in place decades before his death, and even though he shared his views with many other people, he delayed publication of his opus De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres) until right before his death in 1543. This major event in the history of science triggered what we now call the “Copernican Revolution”. He took the same observational data that others were using, but added a much simpler explanatory model—that the planets, now including Earth, orbited the sun.
“Occam’s Razor” (named after William of Ockham, AD 1287–1347) is a well established principle in science. It states that when two theories are in conflict, the one with the fewest assumptions is more likely to be correct. Copernicus’ model was much simpler than the Ptolemaic system. In the same way, the modern geokinetic system is much simpler than the modern absolute geocentric system. In fact, modern versions of absolute geocentrism are far more complex than even the Ptolemaic system, because they have to deal with many more phenomena than Ptolemy was aware of. Therefore, Occam’s Razor ‘cuts’ them deeply.
However, there was room for improvement. For example, he still claimed the planets orbited in perfect circles, and clung to the Ptolemaic idea that the stars orbited in a crystalline sphere far above. Thus he also needed some epicycles to make his theory fit observations. Yet, his logic, math, and observational evidence started a fuse burning. In fact, he played a great role in re-starting the Scientific Revolution during the Renaissance, after the Medieval scientific revolution had been stalled by the Black Death.36 There were still obstacles to overcome, however, and the fact that there was no observed parallax among the stars was used as strong evidence against his theory by many detractors.
What is Parallax?
Put your finger on your nose. Now alternately open and shut one eye at a time. Your finger should move to the left and right as you look at it from each eye. This is called parallax. Because you are looking at something from two different angles, its position seems to shift relative to the background. Now hold your arm out straight and point your finger. Again, alternately open and close each eye. Your finger should still move back and forth, but less than before. Why? Because the difference in the angle between your finger and each eye is much less.
Parallax is very useful in astronomy. The earth’s orbit is 150 million kilometers in radius. Thus, when we look at a star in the summer and in the winter, that is like having two eyes that are very, very far apart. If the star is close, its position will change through the seasons. However, most stars do not measurably change position because they are too far away for us to measure the change in angle. The few that do are closer to us than the ones that do not. Therefore, we can infer the distance to nearby stars, we can infer that different stars are at different distances, and we can infer that some things are very far away. All of this is consistent with geokinetics. In fact, all of this answers one of the gravest objections to geokinetics: the perceived lack of parallax in the early years.
Parallax was also used to determine how far away the earth is from the sun. This distance is called the ‘astronomical unit’ or AU for short and for a long time we did not know its value. Edmund Halley (1656–1742) suggested that we could use the transit of Venus across the sun to determine the AU by getting multiple people to view it and by accounting for the difference in parallax between their locations. This was difficult on many fronts. First, transits occur in pairs separated by several years, but the pairs are separated by 121.5 or 105.5 years! Second, you needed to know exactly where on the earth each observer was and we had not yet perfected the measurement of longitude, so we could only use a parallax based on latitude. Third, you needed to accurately time the event and clocks were only just beginning to be built with enough precision to do this. Fourth, even with a very precise clock, the time difference (seconds) between the start of the transit from one place to the next would be negligible. However, he reasoned that if multiple people measured the total time from start to finish (hours), the accuracy would be high enough to get a good figure. He was correct.
The first recorded transit of Venus across the sun was made in 1639 by a young minister named Jeremiah Horrocks (1618–1641), who projected an image of the sun through a telescope onto a piece of paper [Warning: do NOT try this without proper eye protection, and children should never do this without adult supervision. Concentrating sunlight in this way can permanently damage your eyes.] Horrocks was able to estimate the size of Venus as well as the AU: 59.4 million miles. This was about ⅔ the true value, but it was the most accurate measurement to date. Further sightings in 1761/1769 and 1874/1882 involved some of the greatest international scientific collaborations ever. In fact, the great navigator Captain James Cook (1728–1779), the first person recorded to circumnavigate New Zealand, was sent to Tahiti with the express purpose of recording the 1769 transit (this was successful).
But parallax can also be used to measure the distance to stars. Friedrich Bessel (1784–1846) made the first stellar parallax measurement, of the star 61 Cygni, in 1838! He concluded the star was 10.3 light years distance (less than 10% off), although the parallax amounted to less than 0.00009 degrees. By the close of the 19th century, we had a very good idea of the AU, the size of the solar system, and that parallax was very useful for measuring great distances, and all of that helped to solidify geokinetic theory.37
The recently launched European Space Agency (ESA) Gaia unmanned observatory will be able to measure parallax out to tens of thousands of light years (about 1% of the diameter of the Milky Way). Since stars are obviously at different distances, there is no single ‘crystal sphere’. Are there different spheres? One for each star, perhaps? Maybe the stars are embedded in a universal solid? Perhaps a series of high-tension wires? Or, maybe the universe is geokinetic after all!
Venus transiting the sun, 2012.
Galileo Galilei (1564–1642) was the first person to point a telescope at celestial bodies—and contrary to popular myth, there is no record of anyone ‘refusing’ to look through Galileo’s telescope.38 He was the first to see the moons of Jupiter (and correctly interpreted them as such) and the rings of Saturn. He was the first to see sunspots, which refuted the Aristotelian and Medieval idea of perfect heavenly bodies. He noticed that Venus grew considerably larger and smaller over time, and, with his telescope, observed that Venus went through phases like the moon. The Ptolemaic theory had Venus orbiting the earth quite close to the sun, because we observe it only that way. However, under that scenario, the apparent size would not change by a factor of almost 7.39 This is explained by the fact that Venus orbits the sun at an average distance of 108 million km, while Earth orbits at 150 million km, so its closest approach to Earth is about 42 million km (150–108) and furthest about 258 million km (150+108).40 The phases cannot be explained under the Ptolemaic/Neo-Tychonic model that had Venus orbiting the earth close to the sun without the earth in between the sun and Venus to observe full and gibbous phases. But Venus orbiting the sun explains the huge difference in apparent size, the phases, and why the crescent phase isby far the brightest, since at that time Venus is closest to Earth.41
Galileo was the first to suggest a (correct, and workable when on land) way to solve the “Longitude Problem” by compiling a table of Jovian moon cycles for a reference location (including times and angles), then making observations of these events (same times, different angles) at a location whose longitude is unknown. There is a lot more to this man than most people realize! Much has been written on his trial by the Catholic Church, and urban myths on the subject abound. Let us just say that the Church did not actively suppress geokinetic theory so much as Galileo insulted the Pope in such a way as to permanently break their friendship, at which point his opponents gleefully used the occasion to bring him to trial for heresy. However, Heilbron points out:
A map of known stars within 14 light years of earth, based on parallax measurements. Importantly, they are not just moving with respect to earth; they are moving with respect to each other, meaning the constellations will change shape over time in a predictable manner. Absolute geocentrism can’t explain this in any practical way.
Galileo’s heresy, according to the standard distinction used by the Holy Office, was “inquisitorial” rather than “theological”. This distinction allowed it to proceed against people for disobeying orders or creating scandals, although neither offence violated an article defined and promulgated by a pope or general council. … Since, however, the church had never declared that the Biblical passages implying a moving sun had to be interpreted in favour of a Ptolemaic universe as an article of faith, optimistic commentators … could understand “formally heretical” to mean “provisionally not accepted”.42
As shown above, it was really science vs. science, but Galileo also did not have all the science on his side. His favourite ‘proof’ for geokineticism was the tides, now known to be fallacious. Bede had proposed the right explanation centuries earlier: the moon was the main cause of tides. So the usual atheopathic historiography of science vs. ignorant religious geocentrism is based on historical ignorance and anachronism: many of the geocentrists were following what they thought was the best scientific evidence they had at that time.The detractors err by reading back modern science into people who could not have had this knowledge. We should not make the opposite error by ignoring modern science and adopting absolute geocentrism.
Tycho Brahe (1546–1601) was yet another man of intelligence and diligence who left his mark on history. Without the aid of a telescope, he compiled careful astronomical observations over multiple decades, with a precision equivalent to the width of a US quarter seen at a distance of 100 meters. After the supernova of 1572, Brahe argued that the celestial sphere was not immutable, as Aristotle taught. He then argued that the Great Comet of 1577 traveled through the supposed crystal spheres (meaning they must not exist). In the end, he proposed a mixed model where the other planets orbited the sun but the sun and moon43 orbited the earth. This was supported by the fact that Copernicus’ model did not fit the newest available data (but this was because of Copernicus’ perfect circle assumption).
Brahe also made a good point: that if the earth moved around the sun, then we should see parallax with the stars. Copernicus answered, rightly as it turns out, that the stars were even more distant than the vast distances already imagined. However, not so fast. At the time, stars were thought to have a definite apparent size, and stars like Vega were perceived to be larger than Polaris, for example. So Brahe calculated that if the stars were as far away as Copernicus required, they must be also be unimaginably huge, dwarfing the sun.
These arguments would soon be answered by the geokineticists, but some weakly. One Copernican, Christoph Rothmann, answered Brahe’s point about the huge stars, essentially saying, “Who cares how big the stars are?” because size means nothing to an infinite God. This turns the usual atheopathic science vs. religion canard on its head: here the geocentrist was appealing to science, while a Copernican resorted to a sort of ‘God of the Gaps’44 response.45
However, it was not known—either by Brahe or by his opponents—that the apparent sizes of stars is an optical illusion—almost all stars are really point light sources when viewed from the earth, and the ‘size’ is a refraction or scattering effect. Even with a telescope, the scattering causes the ‘Airy Disc’, as realized by the 19th century scientist Sir George Biddell Airy (1801–1892).46 In reality, Vega, which Brahe thought was huge, is only 2.36 times as big as the sun, but it’s quite close. Polaris, which Brahe thought was a lesser star, is 43 times the sun’s size. The first direct image of a star outside our solar system, in the sense of the stellar disk as opposed to a point of light, was a Hubble Space Telescope picture of Betelgeuse, taken in 1996.47But Betelgeuse really is a huge star, bigger even than the diameter of Jupiter’sorbit, and relatively close (about 643 light years), so it was possible to image its size. However, Airy disc diffraction wasn’t discovered until relatively recently, so we can conclude that Brahe was acting as a real scientist, using the best data available at the time. And although Brahe took Scripture seriously, he based his modified geocentric model on what he thought was the best scientificevidence.48
It is not surprising that for a few years Brahe’s geo-heliocentric theory, and many competing but similar theories, were more popular. Several of those competing theories involved a rotating earth in a geocentric universe, but every one of these, like their Greek progenitors, had a short shelf life. Once the earth spins, the pseudo-biblical arguments (e.g., “The Bible speaks of ‘sunrise’ so the universe must be geocentric”) go up in smoke. And once the earth spins, all the supposed observational evidence for geocentrism suddenly disappears.
Kepler’s Platonic solid model of the Solar system (1596).
Johannes Kepler (1571–1630) worked for Brahe and inherited his data upon Brahe’s death. Unlike Brahe, however, he was an early convert to Copernicus’ heliocentrism, believing that its mathematical elegance reflected the glory of the Trinitarian God of the Bible, and tried to refine it further. His first attempt was ingenious, even though he eventually abandoned it: he proposed that the orbits of the six known planets had the radii of imaginary spheres that circumscribed one of the five Platonic solids (octahedron, icosahedron, dodecahedron, tetrahedron, and cube), with each solid nested in the next with its vertices touching a circle that inscribed the next larger solid, and with all centered on the sun.49 Kepler found that the predictions differed from Brahe’s observations of Mars’ orbit by a mere 8 arcminutes. Since 1 arcminute = 1/60 of a degree, there was thus a tiny difference between observation and theory. The moon’s angular diameteras seen from earth is between 29.3 and 34.1 arcminutes, and Ptolemy’s and Copernicus’ earlier work was precise only to 10 arcminutes. However, Keplerheld Brahe’s observation skill in such high esteem, since they were precise down to 2 arcminutes, that this tiny difference was enough to abandon the theory:
If I had believed that we could ignore these eight minutes [of arc], I would have patched up my hypothesis accordingly. But, since it was not permissible to ignore, those eight minutes pointed the road to a complete reformation in astronomy.
He then developed what are now called Kepler’s Three Laws of Planetary Motion: 1) all planets orbit the sun in elliptical orbits with the sun at one of the two foci, 2) planets sweep out equal areas in equal times, and 3) the square of orbital period is proportional to the cube of the semi-major axis of the orbital ellipse. His ideas were not universally accepted (e.g., Galileo and Descartes both rejected them), but his book Epitome of Copernican Astronomywould become the most-read astronomy text of the era.50 Still, what was lacking was a physical reason for the way things were. At that point in history, astronomy was allied with astrology and mathematics and was thus deeply steeped in philosophy. Physics was treated as an entirely separate subject and Kepler received criticism for even his minor attempts to bridge the two realms.
Table 1: Planetary orbital data.
|Planet||Mass (1024 kg)||Diameter (km)||Gravity (m/s2)||Distance from Sun (106 km)||Orbital Period (days)||Orbital velocity (km/s)||Orbital Eccentricity||Perihelion (106 km)||Aphelion (106 km)|
Isaac Newton (1642–1727) was simply one of the greatest scientists who ever lived. Among his many accomplishments, he developed the universal theory of gravity (1687), which stated that all objects in the universe attract all other objects, and that the attractive force is related to the mass of the two objects and their distance apart.51 He also gave us the Three Laws of Motion: 1) an object at rest will remain at rest, and an object in motion will remain in motion, unless acted upon by an outside force, 2) force, mass, and acceleration are related by the formula F = ma, and 3) there is always an equal and opposite reaction to any force applied to an object.
Think about it: Galileo first saw that smaller moons orbit larger planets. Newton then gave the reason for this. Apply this thought to the solar system. We know size of the sun. The sun has much more mass than the earth. If moons orbit their more massive planets, then the earth (and other planets) must orbit the much more massive sun. At larger scales, we see globular clusters where stars are orbiting their common center of mass, as best as super-computer modeling can tell. Although here is where ‘dark matter’ is often added to the mix, so obviously there is more to learn (e.g. maybe we should adopt the new physics of Carmelian Relativity).52
Importantly, Kepler’s three laws of planetary motion can be directly derived from Newton’s work (in fact, Newton did this). When one uses Newton’s law of gravitation and his 1st and 2nd laws in a heliocentric system, it turns out that one of the foci of the Keplerian ellipses is the barycenter (the center of mass of the system). But Newton went farther than that, and this is part of his brilliance. Newton very carefully explained that evidence for his theory should only be applied to limited sets of data. In building up explanations for various phenomena, results could be pooled into larger and larger explanatory models, but also any deviations from what is expected should be attributed to specific causes. This is one of the most important developments in the history of experimental science, for it led to more and more observational measurements and more and more refinement of his models.
The simple idea that every particle in the universe is attracting every other particle can now explain, to an amazing degree of accuracy, the observational evidence, and that evidence stands in sharp contradiction to absolute geocentrism. There are many chaotic effects even in the solar system (perturbations from objects not yet cataloged), and as a result the math is not as precise as perfect clockwork, as one might expect. But these are small effects. An amazing number of phenomena can be explained. For example, Edmund Halley (1656–1742) announced that the moon appeared to be slowing over time (based on ancient eclipse data). Multiple theories were put forth by very smart scientists (e.g., Euler and Laplace), but Newtonian mechanics eventually won the argument (in the mid 1800s it was concluded that tidal friction was causing the slowing—and its resultant recession53). More and smaller discrepancies were noted over time, and in the early the 1900s the Hill–Brown theory was developed. On purely Newtonian grounds, it accounted for the many small variations in the earth’s rotation in relation to the moon, and most of this was explained by accounting for irregularities in the structure of the earth itself—in other words, further refinements of the Law of Gravity.
Newtonian theory works to an incredibly high degree of precision here on earth, explains satellites, works on the moon, basically works everywhere we have tried it. If absolute geocentrism were true, none of these things should necessarily be true. Nor could we have derived such simple laws, resulting in many true predictions, from a geocentric universe. Therefore, why would we seek an alternative explanation to geokineticism?
For those who think the Bible demands absolute geocentrism, it is notable that Newton wrote even more about theology than science, and thought his greatest work was an exposition of the prophecy of Daniel.54 He saw the solar system as evidence of the biblical God:
This most beautiful system of the sun, planets, and comets, could only proceed from the counsel and dominion of an intelligent Being. … This Being governs all things, not as the soul of the world, but as Lord over all; and on account of his dominion he is wont to be called “Lord God” Παντοκράτωρ [Pantokratōr cf. 2 Corinthians 6:18], or “Universal Ruler”. … The Supreme God is a Being eternal, infinite, absolutely perfect.55
Further, he was scathing of the atheism that dominates so much of academia today:
Opposition to godliness is atheism in profession and idolatry in practice. Atheism is so senseless and odious to mankind that it never had many professors.56
Also, despite accusations to the contrary, Newton was a confirmed Trinitarian, despite not being able to assent to all of Anglican doctrine.57
Before the turn of the 20th century, several problems had become evident in Newtonian mechanics. Urbain Jean Joseph Le Verrier (1811–1877) first noted that the Mercury’s orbit had deviated from Newtonian predictions by a tiny ~40 arcseconds per century. Albert Einstein (1879–1955) answered this by concluding that Newtonian mechanics are valid approximations at low gravity, but at more extreme levels (e.g., the orbit of Mercury), gravity distorts space and time. In his 1916 paper on general relativity, he suggested three tests of his theory: 1) the precession of Mercury could thus be explained, 2) deflection of light by the sun, and 3) gravitational redshift. All three, and much more, have been confirmed.
Einstein’s theories also argue against an absolute-geocentric universe. This is a one-two punch. Geocentrism must address the experimental verification of both Newton and Einstein. Einstein famously said, “A thousand experiments cannot prove me right. A single experiment can prove me wrong” (rough translation). And his theories have been tested, and passed those tests, thousands of times. Thus, it is absolute geocentrism that lacks experimental validation, suffers from experimental contradictions, and supporters are forced to resort to more and more exotic ideas in order to explain away the many contradictions. But Einstein’s theories are based on those of James Clerk Maxwell (1831–1879) and his famous equations of electrodynamics, Hendrik Lorentz (1853–1928) and his equally famous Lorentz Transformations, and Jules Henri Poincaré (1854–1912), whose re-working of the Lorentz Transformation paved the way for Einstein. Thus, geocentrism runs into even more problems with experimental science. The universe is unintelligible under a system of absolute geocentrism and almost everything we think we know about the most profound astronomical discoveries of all time must be wrong.
Frames of Reference
We have often pointed out that when discussing astronomy the Bible is simply making a valid choice of reference frame. Someone sitting in a train does not seem to be moving with respect to the train but seems to be moving quickly compared to the world outside. Likewise, someone standing on the ground outside the train sees the person zipping by at the same speed as the train. The difference is that the two people have different frames of reference. Thus, for someone here on earth, the sun, moon, planets, and stars appear to be circling us, so why should the Bible not use earth as a frame of reference?
And we always talk about a ‘stopped’ car, meaning stopped relative to the ground. Speed limits and stop signs are likewise set relative to the ground, and the GPS in many of our cars uses a car-centered reference frame! Only a pedant would point out that in the geokinetic system a car stopped at the equator travels at about 1,670 km/h (about 1,000 mph) relative to the centre of mass of the earth due to the earth’s rotation on its axis,58 and is orbiting 108,000 km/h around the sun, and is traveling 800,000 km/h around the centre of the galaxy. Sir Fred Hoyle (1915–2001), no friend to Christianity, affirmed:
The relation of the two pictures [geocentricity and geokineticism] is reduced to a mere coordinate transformation and it is the main tenet of the Einstein theory that any two ways of looking at the world which are related to each other by a coordinate transformation are entirely equivalent from a physical point of view. Today we cannot say that the Copernican theory is ‘right’ and the Ptolemaic theory ‘wrong’ in any meaningful physical sense.59
Note that Hoyle is speaking about a coordinate transform between any two reference frames in a geokinetic universe, not a dynamical explanation of the physics involved in how things move in a geokinetic vs. absolute geocentric model. Once you have a set of equations of motions for a geocentric and heliocentric model, you can switch between them. Fine. But once you bring in physics (gravity), one model works with the physics and the other is just a set of equations of motion with no relation to physics. Also, one of Stephen Hawking’s collaborators, South African cosmologist and theistic evolutionist, George Ellis, was quoted as follows:
“People need to be aware that there is a range of models that could explain the observations,” Ellis argues. “For instance, I can construct you a spherically symmetrical universe with Earth at its center, and you cannot disprove it based on observations.” Ellis has published a paper on this. “You can only exclude it on philosophical grounds. In my view there is absolutely nothing wrong in that. What I want to bring into the open is the fact that we are using philosophical criteria in choosing our models. A lot of cosmology tries to hide that.”60
Ellis is speaking here about big bang vs. other cosmological models, not geocentrism vs. geokinetics. The point here is that philosophy often intrudes itself into arguments about how the universe works. Ellis could have said the same about a literally-earth-centred frame. Geocentrists often quote gleefully about supposed geocentric evidence in cosmology, but this is on a galactic scale – a scale far too large to differentiate heliocentrism from geocentrism. If choice of reference frame were the only issue, we would not have a problem with a geocentric reference frame in ordinary usage. However, this is not what modern geocentrists claim. Rather, they insist that the earth is the only valid reference frame, often combined with abusive ad hominem attacks on the faith of the Christian geokinetic pioneers.
Hoyle, Einstein, and Ellis (as well as Cardinal Nicholas of Cusa back in the 15th century) all said we could switch from one to the other just by transforming coordinates. But why would we want to, for any sort of study of motions in the solar system, galaxy, or cosmos? It is true that you can easily switch between Copernican, Tychonic, and Ptolemaic systems because they all relied on circular orbits. You could build a more complex geocentric model with elliptical orbits, but you are still going to fall short, because in order to make a comprehensive geocentric model, you would need dozens if not hundreds of ad hoc parameters added almost willy nilly to explain the many small perturbations that Newton’s model explains with the simple Law of Gravity. Geocentrism does not really have a “model” in a mathematical sense. Thus, the mathematics for converting from a geokinetic to a geocentric universe are almost unbelievably cumbersome. Many modern ‘geocentrists’ make another ad hoc adjustment that should doom their theory by definition: placing the earth off-center—a tacit admission that Kepler was right all along that the sun was at the focus, not the centre of elliptical orbits. Thus, they have a neo-Tychonic system in which the moon and sun orbit the earth but the planets orbit the sun, and all with elliptical orbits. This bait-and-switch is hardly solved by their preferred neologism ‘geocentricity’.61 It was the accumulation of these ad hoc parameters in geocentric models that made scientists seek for a better explanation in the first place. The transform only works in practice at the basest of levels.
The geokinetic argument starts with a very simple Newtonian law: all objects in the universe attract each other according to the inverse square law. Everything else follows naturally from there. Why does not everything in the solar system collapse into the sun? Orbital angular momentum balances the attractive force of gravity. This works until you get to the size of galaxies and galactic clusters, but this is an ongoing field of study among evolutionists and creationists, with multiple competing models. Also, because of Newton’s second law, acceleration = force/mass, the more massive objects accelerate less with the same applied force. So when dealing with objects of vastly different masses, it makes more sense as an approximation that the most massive object is treated as an unmoving centre. In reality, everything in the solar system revolves around the centre of mass (the barycenter). For the earth-sun system, this is450 km from the centre of the sun (0.065% of the radius of the sun),62 so treating the sun as the center is a very good approximation.63
The location of the barycenter of the solar system changes over time based on the position of the planets.
In many ways, the geocentism debate is akin to the “Did men really land on the moon conspiracy“. Why could they not have done so when everything we know about experimental science (from the force of gravity, the properties of accelerating objects, the workings of jet engines, geometry, trigonometry, calculus, etc., etc.) all argue that it is entirely possible? In fact, a motivated high school student could work out many of the necessary calculations. In the same way, the simplicity, elegance, and far-reaching predictive value of geokinetics puts a huge burden of proof on the geocentrist.
In science, there are many useful reference frames. For example, electrical engineers often find it most convenient to use a ‘bug on the rotor’ as the reference frame when studying induction motors, to understand the way the rotating magnetic field ‘slips’. But if you average out the motions of all the stars in our local cluster, we are moving about 70,000 km/h, in the direction of Lyra (geokinetic), and in reference to the galactic center we are moving about 800,000 km/h. To say that all frames of reference are valid, as some do, is the central point of Relativity. However, to then say that a geocentric frame is the only true or valid frame is breaking the very rule they try in invoke. And what is to prevent someone from claiming the center of the universe is at the tip of their nose (‘ idiocentrism’), since that is 100% in agreement with every personal observation any person has ever made?
Supporting Evidence (or, why the earth cannot be at the absolute center)
The rate of acceleration of objects in the universe
According to Newton’s first law, an object in motion will tend to go in a straight line. Thus, in order to orbit something, an object must turn. In other words, it must accelerate— to a physicist, this means any change of speed or direction. Newton’s second law states that the force required is proportional to the mass and the acceleration (F=ma). If the entire universe is rotating (accelerating) around the earth, how much force would be required to keep things from flying apart? And, the farther away the object, the greater the orbital radius, the more acceleration is required. Remember, there is overwhelming evidence against solid spheres holding the stars and planets in place, and since we can measure distance to many stars using parallax, there is no single “sphere” upon which they are stuck. Based on Newton’s laws, we can estimate the mass of many stellar objects and guess at the mass of many more. The force required to hold them in circular orbits around the earth at faster-than-light speeds (see below) would be astronomically huge.64
The speed of objects in the universe
If objects are rotating around the earth, we can calculate the speed at which they are moving, and the speed depends on their distance. They must travel the circumference of their orbit every day. In big bang theory at least, there is nothing preventing stars from moving faster than the speed of light. This is called ‘superluminal speed’ and big bang cosmologists assume that anything outside one Hubble radius (about 14 billion light years) is receding from us at greater than c. But in a geocentric universe any object beyond the orbit of Neptune would be moving faster than c, because it would take more than one day to travel a circle of that circumference at the speed of light. If geocentrism is true, there should be a ‘spatial Coriolis’ seen in the Pioneer probes and other objects we have sent into the heavens. Here on earth, the Coriolis force is seen when objects traverse an inertial reference frame other than the one in which they started. There should be a ‘spatial Coriolis’ as well, because objects leaving earth are starting with an inertial reference frame radically different from the one to which they are travelling. If we aimed them at a planet, they should miss—by millions of miles! Note that this argument is exactly the same as the one Copernicus quoted from Ptolemy above, only here instead of a curving falling object we have a curving rising object.65 In order to get to a planet, the ship would have to accelerate to unbelievable speeds. Where does this extra propulsive force come from? And if that acceleration did not happen, if one of our ships happened to run into one of the distant planets it would smack into it at such a high velocity as to completely obliterate the planet. This underscores the hopelessness of deriving any dynamical model for geocentrism once we leave the vicinity of the earth.
Here is another example of the speed problem: the moon orbits the earth at about 1 km/s, with an average distance from the center of the earth of 385,000 km (this is based on simple trigonometry). In a geocentric universe, instead of orbiting every 27.32 days, it orbits daily, meaning it must move about 27 km/s. This is much faster than the Apollo spacecraft sent to the Moon in the 1970s. In fact, it is faster than the 11.2 km/s required to reach escape velocity. The Moon should sail away into space, but it does not because it is not orbiting at that speed and is held nicely in place by the force of gravity.
And think about what would be required to bring a long-period comet in from the apex of its orbit (aphelion) to a close approach with the sun (perihelion). We can estimate the mass of many different comets (and after the Rosetta/Philae rendezvous described above, we know the mass of one comet to a high degree of precision), and thus we know how much force it would take to account for the necessary acceleration to bring them closer in within a geocentric universe. To go from a speed reater than c to a speed much less than c, and then back again, comets would have to come with warp-drive.
Yet another speed problem comes from our own humble satellites orbiting the earth. Under Newtonian physics and a rotating earth, a satellite will appear stationary in the sky if it has a circular orbit over the equator, and revolves in the same direction and speed of the earth’s rotation. That is, it has an orbital period of one sidereal day (23.934461223 hours). Such a satellite is called geostationary, and for this to work, the satellite’s altitude must be 35,786 km (22,236 mi) above sea level. Only at that height will the earth’s gravity provide the right centripetal acceleration to produce the orbit with the right period. (Note, geostationary orbits are a subset of geosynchronous orbits: the latter merely have a period of one day so keep up with the earth’s rotation, but if the orbit is elliptical or slanted, the satellite will not appear stationary.) But if the earth doesn’t move, then the satellite must also be unmoving. So much handwaving must be invoked to explain how a rotating universe manages to suspend a satellite motionless in space at just that altitude rather than succumb to the earth’s gravity.
Aberration of starlight
The velocity of the earth changes as it orbits the sun, therefore the expected position of the sun changes over time. In the same way that rain seems to fall at an angle while driving in a car on a rainy day, the perceived direction to various stars shifts as the earth revolves around the sun. This was first noticed in the 1500s, but it defied explanation and interfered with the search for stellar parallax. Aberration was first explained by James Bradley (1693–1762) in 1729. He also provided a decent approximation of the speed of light (183,000 miles per second, 98.4% of the true value). Aberration is a direct effect of the earth’s movement about the sun and is perfectly consistent with Newtonian physics. Under geocentrism, however, arbitrary explanations must be invoked to explain it.
Think about it. If the universe revolves around the earth, stars circle the earth 365 times a year. For a star exactly 10 light years away, the star would revolve 3,652.42 times before its light reached earth. In other words, the light beam should trace out a path that looks more like a very tight spiral, with arms 24 light-hours apart (assuming a finite and constant speed of light). This would be able to be measured easily. And, since we have sent multiple space probes (with cameras) far enough away from earth, this would have been discovered by now Thus, the stars do not rotate about a stationary earth.
The Discovery of Neptune
In 1781, Sir Frederick William Herschel (1738–1822) discovered the planet Uranus. Upon subsequent observations, its orbit was worked out by Anders Johan Lexell (1740–1784). However, slight disturbances in the measured orbit of Uranus led to the prediction of another, undiscovered planet by Le Verrier in 1846. Neptune was discovered by Johann Gottfried Galle (1812–1910) the same evening Le Verrier’s letter to him predicting the existence of an undiscovered planet arrived at the Berlin Observatory. This was perhaps the greatest achievement of the Newtonian system, and ranks as one of the greatest achievements of experimental science. The perturbations of Jupiter and Saturn on Uranus are greater than that of Neptune and it was only by applying Newtonian gravitational theory to the situation (by factoring out the effects of Jupiter and Saturn) that Neptune could be discovered. What is even more amazing is that Uranus, with an orbital period of 84 years, had not even completed one orbit of the sun before it was used to find Neptune! We were able to better estimate the mass of Uranus after the Pioneer flybys of Neptune. This, in turn, answered a riddle that was created by earlier, less exact estimates and the need for a hypothesized 10th planet to account for certain discrepancies simply vanished. Can you see how Newton’s methodology has led to further and further successful refinements of the geokinetic system?
Absolute geocentrism could never have predicted Uranus and Neptune from orbital mechanics. Remember, both the Ptolemaic and Tychonian models are kinematic: they merely describe how planets are observed to move. Any observed deviations are just tacked on to the model—what’s another epicycle here or there? Only under a dynamic model, with forces causing motions, can a deviation from predictions have any real meaning.
The Return of Halley’s Comet
Alexis-Claude Clairaut (1713–1765) successfully calculated the return of Halley’s comet to perihelion in 1759. In order to do so, he had to account for the gravitational effects of Jupiter and Saturn on the comet, and the effects of Jupiter on the sun. Using the most advanced mathematics of the day (calculus), his detailed calculations took years. In the end, he was off by about 1 month, within his margin of error. This was taken as a triumph of Newtonian gravity theory and helped tremendously to bring mathematics and physics together. Prior to this, many thought math was just pure, applied logic and that the physical world was nothing if not mysterious. Theory and fact were not always expected to mesh together. This changed after 1759.66
Delicate orbital mechanics
There are several places in any planetary system called Lagrange points where the gravitational attraction of the sun exactly balances that of the planet, meaning an object can orbit at the same rate as the planet even though it is a different distance from the sun. The first three Lagrange points were discovered by the great mathematician, and staunch Christian, Leonhard Euler (1707–1783). In 1772, his able student and successor Joseph-Louis Lagrange (1736–1813) described the remaining two. These discoveries (and their later confirmation) were squarely based on Newtonian theory. In a fine example of applied Newtonian physics, ESA’s Gaia space telescope is placed on a Lagrange Point (L2, specifically). It was already known that L2 is unstable (small deviations from equilibrium grow exponentially over time), so in order to keep the satellite in place while using the smallest possible amount fuel to fine-tune the position, it was placed in a looping, Lissajous orbit that also had the effect of keeping it out of earth’s shadow. This elegant dance was made possible by geokinetic theory.
The equatorial bulge
Newton noticed that Jupiter had an equatorial bulge and reasoned that this was due to the fact that it was rotating, causing a fictitious centrifugal force in Jupiter’s reference frame.67,68 He then reasoned that earth must have a bulge as well and set about to estimate its magnitude. It turns out that sea level at the equator is about 21 km ‘higher’ than at the poles. Other rotating bodies also have an equatorial bulge, including Mars, Saturn, Uranus, Neptune and the asteroid Ceres. At the equator, there is a reduction in apparent surface gravity of ½ of 1% compared to the poles. 70% of that is due to the ‘centrifugal force’ counteracting the attractive force of gravity. The remainder is due to the difference in distance from the center of the earth caused by the bulge. However, this is enough to make the furthest surface point from the earth’s center the summit of the equatorial volcano Chimborazo, not Everest. The equatorial bulges of objects in near space are due to rotation. Earth has a similar bulge. Geocentrism must claim the two phenomena are due to different causes, which is nonsensical.
To be fair, geocentrists could in theory solve the problem with relativity. Max Born (1882–1970), Nobel laureate and quantum mechanics pioneer, pointed out:
Thus we may return to Ptolemy’s point of view of a ‘motionless earth’ … One has to show that the transformed metric can be regarded as produced according to Einstein’s field equations, by distant rotating masses. This has been done by Thirring. He calculated a field due to a rotating, hollow, thick-walled sphere and proved that inside the cavity it behaved as though there were centrifugal and other inertial forces usually attributed to absolute space. Thus from Einstein’s point of view, Ptolemy and Copernicus are equally right.69
But here again, Born just said it was possible, not mandatory or even practical. For example, earthquakes can affect the earth’s rotation because they can redistribute mass, and this can be calculated relatively strightfowardly. But using the absolute-geocentric explanation would entail that an earthquake affects the entire universe. And ironically, many absolute geocentrists reject relativity, since they don’t want to concede that non-geocentrism is even as right as geocentrism.70
The oddly wiggling universe
If the earth is the center of everything, we must explain why events happening here on earth affect the rest of the universe. For example, Bradley discovered that the earth wobbles on its axis much like a spinning top wobbles as it revolves. ‘Nutations’ like this are explained by Newtonian theory to a high degree of accuracy, but would be nothing more than arbitrary changes in the rotation of the cosmos under geocentrism. And earthquakes, like the one that caused the massive tsunami that hit Japan in 2009, are known to affect the rotation of the earth. Scientists actually measured a change in the rate of rotation of the earth after that event. If geocentrism is true, nutations and earthquakes change the rotational speed of the universe instead. Yet, strangely, even though there is no reason to believe all objects in the universe are connected, they all change their rates of rotation at the same time. And these objects are at vastly different distances to the earth. Thus, there is a time delay that must be accounted for. Do objects further out change earlier than objects closer in, and are all these sequential changes timed to future events here on earth? No. We see everything in the universe changing at the same time because it is the earth itself that is changing its rotational speed.
This is named after the French engineer and mathematician Gaspard-Gustave Coriolis (1792–1843). Newton’s Laws of Motion say that an object will move in a straight line unless an outside force acts upon it. This applies to any motion across the earth or any rotating body—any outside observer would see straight line motion.
But from the viewpoint of a stationary observer on the rotating body itself, the motion would appear to be deflected. This is due to the fact that an object, decoupled from the moving and rotating earth, will travel in a straight line irrespective of what the earth itself does. So to apply Newton’s Laws, a fictitious force or pseudo-force must be postulated to cause this ‘deflection’. This is the ‘Coriolis Force’, acting perpendicular to both the rotation axis and the object’s motion.
This is important for cyclones, a large-scale weather pattern where air flows into a low-pressure region. Instead of flowing straight in, the air is deflected, so that cyclones flow counter-clockwise in the northern hemisphere, but clockwise in the southern hemisphere.
Because the earth is rotating so slowly—once per day—the Coriolis effect is negligible except over long distances.71,72 There is simply no good reason to attribute the observations to the universe spinning around a stationary earth.73
And when we look at the Great Red Spot on the southern hemisphere of Jupiter, we note that it behaves exactly like hurricanes do in the northern hemisphere here on earth—rotating anticlockwise (counterclockwise). That’s because hurricanes have wind rotating inwards towards a very low pressure area, while the Spot is an anticyclone (winds are spiraling outwards from a high pressure area). And, of course, the Spot is larger than any earth hurricanes—in fact, larger than the whole earth. From all appearances, its behavior is due to the Coriolis Force acting on an anticyclonic gyre moving across a spinning planet. We can observe Jupiter spinning. We see evidence of the physical effects of that spin. Now look at earth. We see evidence of the physical effects of spin in the Coriolis Force. Does this not mean that the earth also spins?
There are many other geokinetic examples we could have brought into this discussion. We decided to stick to these few examples only, and we ordered the examples starting with the most important. When all is said, it is clear that absolute geocentrism has extreme problems. We would encourage anyone dabbling with non-Newtonian ideas to let go and let the earth find its own place in the heavens.
The triumph of geokinetic theory is one of the greatest examples of the pursuit of science in the history of man. It was pioneered by scientists with a biblical worldview, affirmed by theologians with a biblical worldview, and is accepted today by people with a biblical worldview. It also fits all the relevant data. These are the reasons why we support it.
The greatest contribution of Western science, pioneered by Christians as it were, is the idea that the universe is rational. This is in line with the biblical presupposition that the universe behaves in an orderly manner because the Ultimate Lawgiver would not have created something that goes against his very nature. Our God is unchanging. There is no ‘shadow of turning’ with him (James 1:17). He is not fickle. He is not like pagan gods. He is not like Zeus, sitting on Mount Olympus waiting to throw down a lightning bolt whenever he wants to mess up a person’s life (or experiment). He is not ‘chaos’, which would prevent rational interpretations of events. He is not ‘nature’ – if nature were alive, it would have a volition of its own and science would not be possible. No, our God has created a universe for us to live in and that exults His name. He has also told us to use our minds and to understand the universe He made for us. This universe, therefore should be understandable, and geokinetic theory makes such an understanding possible.

The negative sign means attraction, because it’s in the opposite direction to the vector from one of the bodies travelling to the other.

- Newton actually denied arguments for the Trinity from dubiously attested biblical texts, such as the Johannine Comma in John 5:7. Most informed Trinitarians today would agree that the texts are dubious. A very detailed defense of Newton’s Trinitarianism is Van Alan Herd, The theology of Sir Isaac Newton, Doctoral Dissertation, University of Oklahoma, 2008; gradworks.umi.com/3304232.pdf. This documents much evidence, including Newton’s words refuting tritheism and affirming Trinitarian monotheism, e.g.: “That to say there is but one God, ye father of all things, excludes not the son & Holy ghost from the Godhead because they are virtually contained & implied in the father. … To apply ye name of God to ye Son or holy ghost as distinct persons from the father makes them not divers Gods from ye Father. … Soe there is divinity in ye father, divinity in ye Son, & divinity in ye holy ghost, & yet they are not the forces but one force.” The argument against Newton is like someone 300 years from now citing our page ‘Arguments we think creationists should NOT use’ and claiming that CMI is anti-creationist.

- Ptolemy was correct, by the way. Objects should curve as they fall, but he had no way to measure the effect because he could not get high enough to drop an object and see the curve. Indeed, when manned space ships are re-entering earth’s atmosphere, rocket scientists must account for both the horizontal motion of the ship as well as the rotational speed of the earth in order to land in the correct place. If a non-orbiting object (e.g., something orbiting the sun in the vicinity of earth) were to fall, say, from the altitude of a geostationary satellite, it would NOT fall in a straight line. In fact, it would appear to curve as the earth rotated beneath the falling object. Return to text.

- Under Newton’s First Law, any object with no force acting keeps moving in a straight line. So an object moving in a circle has a tendency to fly off in a literal tangent, just because of its inertia, with no force needed. But to observers on the rotating reference frame, it seems as if there is a force acting that pushes objects away from the center, i.e. centrifugal (‘center-fleeing’). This doesn’t exist in inertial reference frames. Return to text.

This is a myth—rather, an irregularity in the shape and latent water motion would almost always cause some turning in the flow towards the hole. As the water flow converges on the hole, the diameter shrinks, so the rotation rate increases. This is because of the Law of Conservation of Angular Momentum, which also explains why a spinning ice skater speeds up when she pulls her arms in. Return to text.
- In rotational-vibrational spectroscopy, if the molecule is rotating very fast, as the atoms vibrate they will experience Coriolis effects in the molecule’s rotational reference frame. So there is a need for correction terms known as Coriolis zeta coupling constants. Return to text.
You stated: “this passage [Isaiah 38:8] is entirely ambiguous. It does nothing to inform us of the workings of the universe.” You seem to think that saying something makes it so. There is not any ambiguity in the passage, and that passage speaks directly to the workings of the universe. The foundation of your biblical argument is a “phenomenological language” tradition that requires three assumptions: 1) someone other than God is viewing the phenomenon, 2) that someone is telling us what he saw, and 3) and what he saw did not actually happen as he described it. First of all, it is God speaking in Isaiah 38:8. Verse 4 states “then came the word of the Lord to Isaiah.” Isaiah was speaking the words of God Almighty. God stated what he would do: “Behold, I will bring again the shadow of the degrees, which is gone down in the sun dial of Ahaz, ten degrees backward.” God then stated exactly how he did it. “So the sun returned ten degrees, by which degrees it was gone down.” God says, without ambiguity, that the sun returned the very ten degrees that it had gone down. Yet, you state the passage is ambiguous. However, the alleged ambiguity, according to you, only cuts one way, and that is directly contrary to the express meaning of the words used. Under your “phenomenological language” tradition, you are saying that in fact the sun did not return the ten degrees it had gone down. Please explain to me how your “phenomenological language” tradition does not contradict what God clearly states? How is what you are saying any different than that for which Jesus rebuked the scribes and Pharisees? “Making the word of God of none effect through your tradition, which ye have delivered.” Mark 7:13.
Simple. And I have already done so. Both geocentrism and geokinetic theory can be satisfied by one of the stated mechanisms. If you or I were standing there looking at that shadow, measuring the angle to the sun, you and I would both say the shadow and the sun went back. It is "ambiguous" because the language cannot be used to separate the two theories. Yup, without ambiguity, the Bible says the shadow went back. You are putting words in my mouth by claiming I believe the 'sun did not return the ten degrees it had gone down'. The passage is not ambiguous as to what happened. If you wanted to use that as an experimental setup, however, the results would be ambiguous because you cannot use the results to make a decision between the competing hypotheses. A "Type C" experiment, as I explained in an earlier comment.
Caution: You are taking up a lot of space and time. This is not an open-ended forum. You've made your best case against phenomenological language and I have replied. If you want to stay on the same topic, we are not under any obligation to keep responding. FYI.
I agree with BOTH of you (smile), both Edward H and Robert Carter, about the sun dial, because any and all of the discussions about any and all motion of any physical objects in the universe is mathematically RELATIVE, just as Einstein et al said. And that it is only a matter of choosing one’s coordinate system that changes. Therefore Mars-centricity is just as valid mathematically. Grab the universe in any given point and hold it still and the motion of all the other objects in space will not change observationally.
“So which is real, the Ptolemaic or the Copernican system? Although it is not uncommon for people to say that Copernicus proved Ptolemy wrong, that is not true … one can use either picture as a model of the universe, for observation of the heavens can be explain by assuming either the earth or the sun to be at rest.” -- Stephen Hawking, Physicist
“Let it be understood at the outset that it makes no difference, from the point of view of the describing planetary motion, whether we take the Earth or the Sun as the center of the solar system. Since the issue is one of relative motion only, there are infinitely many exactly equivalent descriptions referring to different centers – in principle any point will do … So the passions loosed on the world by the publication of Copernicus’ book De revolutionibus orbium coelestium libre VI, were logically irrelevant …” – Fred Hoyle, Astronomer
What is needed is scientifically observable independent evidence of whether the earth moves or not. And the Michelson-Morley experiments provided that evidence. A serious IN DEPTH discussion about Michelson-Morley needs to take place in this forum.
Yup, from the point of view of describing planetary motion. We said as much in the article. Mathematical models of motion can go either way. However, explanations of the physics involved cannot. This was the main conclusion of the article and this is what our detractors are assiduously avoiding. You did read the article, right?
Sadly, this comment thread is not a suitable venue for an in-depth discussion of every aspect of M-M. But I have already answered the main contentions (in two places) above. There is not much more to say. And, as I have told two other people, we've given you enough space to make your case. Blessings to you.
You subtitled the article “Refuting absolute geocentrism,” but you did no such thing. A refutation is proof that something is wrong. You presented arguments against geocentricity, but your article can hardly be termed a refutation. To refute geocentricity would require proof. However, you have craftily dodged and avoided some strong scientific and biblical arguments that support geocentricity. For example, you made passing reference to Isaiah 38:1–7, but you did not cite or discuss the operative passage that proves geocentricity, which appears in verse 8. Why not? If you are refuting geocentricity, one would think that you would address Isaiah 38:8. “Behold, I will bring again the shadow of the degrees, which is gone down in the sun dial of Ahaz, ten degrees backward. So the sun returned ten degrees, by which degrees it was gone down.” Isaiah 38:8. That passage clearly states that “the sun returned ten degrees, by which degrees it was gone down.” God is stating clearly that he moved the shadow on the sun dial ten degrees by moving the sun back in its path by ten degrees. Your statement that God is using “phenomenological language” in the bible passages that support geocentricity is just a clever way of saying that God is telling us a fib, because we are too dense to understand what is really happening. God could have easily stated that he moved the earth back ten degrees in its rotation, if that is what he had done. I think we could understand that phenomenon. God did not say that, because he did not do that. God is not lying to us about what he did by using what you call “phenomenological language.” God explained exactly what happened, “the sun returned ten degrees, by which degrees it was gone down.” Isaiah 38:8.
We have not ‘craftily dodged’ anything, and your argument really amounts to nothing. The refutation is in the physics, and so far nobody has attempted to seriously grapple with it, which is telling.
Regarding Isaiah 38:8, the shadow went backwards in the reference frame of those doing the observing. If that happened today, the first-hand reports would use the exact same language even though later pundits would state the earth must have temporarily reversed its spin. I note that God did not say the universe reversed its spin around the earth, only that the sun/shadow went back, which could happen in a geocentric universe if God reversed the spin of the universe OR if He temporarily decoupled the sun (and planets!) from the rotation of the universe. In a geokinetic universe, God could reverse the spin of the earth OR move the sun and planets in their place to produce the same effect (thank you for making me think of this last bit). Therefore, this passage is entirely ambiguous. It does nothing to inform us of the workings of the universe.
Nobody is being duplicitous.
Thank you, Dr. Carter and Dr. Sarfati, for your willingness to engage in what is still a hot topic centuries after Galileo and Copernicus.
I consider myself not fully convinced of either side in this debate, and this article did little to help that unfortunately. A chief reason for that is the lack of any mention of the fairly recent work by Robert Sungenis on this topic. See especially his work with Robert Bennett called "Galileo Was Wrong, The Church Was Right". It's a 3-volume work detailing the problems with heliocentrism (or a geokinetic earth, as you say) and defending geocentrism. I believe the thrust of these volumes may be in direct contradiction to your statements in this article
Since I didn't see this work or its authors mentioned in either the article or the comments, I was wondering what your thoughts were on this work. If you disagree with the assertions and conclusions made by Sungenis and Bennett, I would be interested to hear why. If you haven't read it, I recommend it; I think it belongs in the conversation.
Like you, I want to follow the truth where it leads. It was following the truth that lead me to stop accepting the lie of evolution. CMI helped me tremendously in that capacity. Perhaps CMI can help me with this, as well.
Thanks for your hard work on this article and the many other articles you both have written!
Sungenis was the main driver behind the geocentrist movie The Principle (there is a link to a review of that movie in a reply to a comment from Gre T. above). As a Catholic, he has great trouble with several of the great Solas of the Reformation (Sola Scriptura -- the Bible alone, and Sola Fide -- by faith alone, specifically). He and Bennet co-wrote Galileo was Right, The Church was Wrong.
As I said in a comment above, our purpose was to put the best case forward for geokinetic theory and not to allow ourselves to get bogged down by addressing the claims of the geocentists. As you can see from the comments, however, we have now handled many of their claims. So in the end their book was brought into the conversation. Indirectly, but according to plan.
For those out there (like you) who might be sitting on the fence: Put on your thinking caps. Look at the evidence for both sides. Look at the way each side handles Scripture. Look at how each side understands the fundamental processes involved. It is our contention that they are mishandling Scripture and that they do not understand what they are talking about on fundamental levels. The train of recent comments should make that clear. There is a rational viewpoint that is also a faithful viewpoint and that takes into account all of the relevant scientific and Scriptural data and savages neither. It is geokinetics.
Thanks, Robert, for your correction!
My apologies. My analogy of the moving train should’ve only had one boy, catching a pitch from a stationary man. But now a simpler analogy might prove my point:
Picture instead a turntable with an LP record (the fabric of space) painted with white dots (stars) spinning once in 24 hours around a small stationary bug (a rocket ship) perched on a stationary spindle (earth) preparing to travel to a dot (Pluto) on the LPs outer edge. Admittedly the bug would have to exert a certain angular force in order to safely step on to and adjust to the rotational momentum of the spinning LP and point itself to Pluto.
BUT, once he adjusts to this spinning reference frame AFTER ONLY A FEW STEPS and aligns himself with Pluto, then he only has to travel in a STRAIGHT LINE to get there, requiring only LINEAR thrust from that point on. From the bug’s PERSPECTIVE the stationary spindle (earth) is now spinning behind him; while the stationary spindle perceives the bug as being on a curved trajectory towards Pluto. But, again, this is only a PERCEIVED curve, not a real curve (after alignment), because it is a different (a spinning) reference frame. From the bug’s perspective, he is now walking straight, with Pluto straight in front of him, exerting only a LINEAR speed, NOT and angular speed. The bug’s angular speed is only a PERCEIVED speed “seen” by the spindle. The point is that the bug only had to exert angular force BRIEFLY at the beginning near the earth to get aligned, NOT for the entire trip “to catch up to” a speed-of-light-traveling Pluto. To him Pluto is now stationary. Does that work? The math should work out the same in a geokinetic system. Corrections welcomed.
You are having difficulty coming up with working analogies because your basic premise is incorrect. In this case you are demonstrably wrong again. Space is not a 'hard' medium, the record is. There is essentially no friction in space (and many experiments have already shown this). As a ship moves outward in a geocentric universe, it will have to accelerate sideways or it will not travel in a 'straight' line. In fact, your analogy will break down as soon as the ship gets far enough out on the record that friction ceases to hold it in place. The ship, if traveling, is not anchored to the medium. And if it was, it could not move.
You are failing to account for inertia. If the interstellar medium is 'thick' and simply carries the ship along in the universal rotation field, there should be a lag (i.e. acceleration), unless it is infinitely thick (like if you were moving inside the vinyl record). But if it is infinitely thick, how does any object move through it? Or is it absolutely thin in the direction of travel and absolutely thick orthogonal to the direction of travel? I think any reasonable person would conclude you were just making things up if you tried to argue this.
NASA never takes into account any 'certain angular force' in order to 'step on to' any interstellar medium, yet their space ships fly straight and true. Why is this? It is because geocentrism is an incorrect physical model.
Thank you for trying. Thank you for explaining to the best of your ability. I am glad to have this exchange saved for posterity so that our readers can see which is the stronger of the two views. You have had four tries and, unless you have some really stellar new argument that no one has ever thought of before, this conversation will end here. Blessings.
All this invective language which has come about as a result of this solidly written article highlights the reason why it was needed in the first place. Onlookers here may think geocentrism is a religion in itself. I’ll quickly say, I admire the geocentrist’s commitment to upholding what he feels is biblical truth. However, I wish that their faith in God would be stronger than something which MUST be propped up by the precarious tenet of geocentrism.
God created man to dwell on, subdue, and have dominion over the earth, so it’s our reference point. From that point, it is perfectly valid to say the sun moves around the earth. Likewise, it’s okay for me to say I am cold when my temp drops to 97 degrees even though my body is still basking in heat hundreds of degrees above absolute zero. Since we use this type of language to help others understand our experiences, it is only logical that God would also use phenomenological language, in our reference point, using our terms, to help us understand His Word. Imagine if God would have chosen that the entire Bible were written on His omniscient terms from His over-arching perspective. We’d find it hard to understand a word of it.
Even if geocentrists postulate that the fabric of the universe itself (space-time) is turning once every 24 hours, dragging all stars with it, there would still be problems. The earth would be compelled to turn with the medium as well at the same rate and the stars and sun would not go across the sky at all. A fix to this problem would be to say the earth is turning opposite the rotating space-time but, alas, that would also violate their beliefs; the sun would not be moving but the earth would.
Kudos on the article! It’s been a pleasure to read Dr Carter's responses and to meet Dr Sarfati Sunday.
I sincerely appreciate your response and light-speed response. Further regarding the speed of objects measured in different reference frames, I think our disagreement boils down to the term “in relation to”. A simplified example for the point I’m advocating is the classic illustration of a man on the ground observing a ball being thrown by two boys in a passing train.
We may still disagree, but what I am saying is that the ball the man “observes” being thrown actually does NOT travel at a faster speed than it is thrown by one boy to the other. I’m saying that there is only be one TRUE speed of the ball, which can only be measured in one chosen reference frame, not across two; therefore, not “in relation to” another reference frame.
This means that the ball’s speed “in relation to” the man on the ground (the train’s speed + the thrown ball’s speed) is fictitious, and doesn’t exist in reality. Why? Because the instant the man begins to add the speed of the train he has changed his measuring reference frame to the train, thus eliminating the “in reference to himself” portion of his equation.
Likewise, if the man chooses to start measuring the ball’s speed the instant it’s thrown, for him to get the balls true speed he must stay in his reference frame (ignoring the train’s speed, which is irrelevant, because from the man’s reference point, at the INSTANT the boy throws the ball, the boy must be considered motionless – for an instant is not a span of time). The ball’s speed according to the man must be calculated as if the boys did not transverse further in the moving train.
I simply applied this principle to the stars rotational motion. But I’m open to correction.
Perfect analogy, but you are missing the critical part. We are not concerned about two boys in the same reference frame (throwing a ball to each other on a 'moving' object). We are concerned with you getting a ball to one of those boys on the speeding train. If you wait until the boy is almost even with you, you are going to have to throw the ball in the direction the train is traveling and at close to the speed of the train. If you simply lob the ball across, you are going to kill him with a 100 mph fastball to the head (because the ball is basically at rest with respect to the earth, not the speeding train). If you throw it faster then the train, the ball will slowly sail past him (take your throw speed and subtract the speed of the train to get the relative velocity as the boy sees it).
In the same way, I am on earth. The boy is on a planet circling the earth. In order to get the ball to the boy, I have to throw the ball at the apparent (to me!) speed of the planet. And that speed, to me!, is many millions of miles per hour. Because we can use simple trigonometry to determine the distance to objects in our solar system, and because those objects must circle us once per day in your model, the relative speed of any object to us at a distance beyond Neptune is >c.
How do we accelerate space craft to that velocity? And, since nobody at NASA takes into account the idea that the place we are trying to get to will spin around the earth many, many times before we get there, how on earth (pun intended) can we actually hit the target?
Based on your reaction to this, I will be forced to either conclude you are deliberately playing fast and loose with your terminology or you don't (or didn't) understand relative reference frames.
Regarding the Speed of Objects in the Universe you say that the rotational speed of an object depends on its distance from earth. This is a physical fallacy. An objects speed is only calculable within its own reference frame. The notion of calculating speed across reference frames is nothing more than an illusion, despite what Einstein said. From the earth’s perspective a star or galaxy 100 million lights years away, still travels at a rotational speed of 24,000 miles per day in relationship to the earth, but the star itself does not travel AT ALL in relation to its frame of reference and the other stars. Its frame of reference is the fabric of space. And even if space stretched it would not change the distance because measurements would stretch too.
To puts it another way, for all it cares, a star doesn’t travel at all (it only sees the earth “spinning”), whereas the earth sees any distant “stationary” object as simply traveling the circumference of the earth in one 24 hours. Any assumptions beyond that are only calculations of PERCEIVED speeds not, not of ACTUAL speeds. This is why we say that “to the observer” (in a given reference frame) an object in a different reference frame “appears” to be traveling at a different speed. But in reality it is precisely BECAUSE the two different reference frames are not the SAME referenced frame that one cannot legitimately claim that one frame CAUSES a speed change of an object in the other. Therefore it is incorrect to say that an object circling the earth travels at a different speed depending on its distance from the earth. Perceived speed is not real speed.
What a curious amalgamation of disparate notions. And no amount of fancy language is going to obscure the fact that you have entirely missed the point. You believe the earth is sitting still. Now, a space ship on earth is launched at a distant object (let's say Pluto). That space ship MUST accelerate to the speed of the object if it wants to get to that object without 1) missing entirely or 2) smashing into it at faster-than-light speed. You cannot bring up relativity for we do not care how the earth appears to that distant object. Our only concern is the fact that the ship must get to a significant radius away from the earth and that the horizontal speed relative to the earth (for the ship started at rest -- the reference frame of earth) must match the circumference of a circle with that radius every 24 hours. Physical fallacy? An object's speed can only be calculated within its own reference frame? Nonsense! We are talking about the speed of an object in reference to the earth.
I will ignore the fact that you claim the stars only have to travel 24,000 miles per day. Adding "in relation to the earth" is nonsensical. There's a lot about geometry, even in our article, you seem to have missed.
In a number of places in this comment section you say that writers make refutations but don’t provide evidence or documentation. But how can we provide adequate proof and documentation when we are only allowed 300 words to respond to a paper that is many, many pages long?
I have written very solid refutations on many of the key points I disagree with, but have no way of posting them for everyone to see. Therefore you have the advantage because you were able to post your whole paper, but we can’t sufficiently respond with only 300 words. Granted, you say that for long responses to use the contact page. But if we do will our responses be posted for all to see?
We are all doing our best with the technology available to us. Yes, the limit is 300 words and, no, we cannot post something longer. However, one can say a lot in 300 words. Instead of trying to write a full-on broadside against geokinetics, how about just firing your best shot? So far, several have put forth ambiguous experiments, claimed the Bible absolutely means X when it does not necessarily mean that, or claimed the evidence we presented was nothing but lies. No one has yet attempted to substantively answer our main scientific arguments, and there is space enough to do so. Indeed, I have managed to answer every comment so far in the same amount of space.
Thank you so much for your compliment. Joshua's Long Day occurs after Genesis 2:2, so miracles were still occurring and thus naturalism would have been an invalid interpretation of that phenomenon. The article you linked to me was actually the reason for my question: your view contradicts the view in that article slightly. That article rejects naturalism as a rule. It essentially argues that miracles are so infrequent that scientists can still do well enough by assuming God isn't interfering with their experiments. But to be sure, that article says that God could, if He wanted, interfere at any time and suspend naturalism. You say the universe behaves according to a set of rules, but this other article makes it clear that there are an infinite number of rules that God may chose to apply at any moment based on His literally infinite wisdom. For all we know, the rapture could start tomorrow. Lastly, has there been a study on the frequency of miracles? Could there be many miracles that no one knows about? Because, I actually like the argument that we can still do science if miracles are infrequent, but it would be cool to get a frequency estimate.
The two articles are not in conflict. God can do with His creation whatever He sees fit, and at whatever time He chooses. The fact that He chooses to generally operate according to a set of self-appointed rules means that science can work. This also means that the times He does not (the Virgin Birth, for example) can be identified as miracles.
I am not aware of the frequencies of miracles, nor indeed do I believe it is something that can be calculated. Miraculous events in the Bible, before Christ, were separated by decades, sometimes centuries, but this does not mean the Bible recorded every one. Etc.
To summarise your article and its intent: BECAUSE Man has gone to the moon and sent out Rosetta to a distant rock THEN Geokineticism (moving earth) must be TRUE because it is the only model that explains them.
These are lies and illusions generated through computer imagery. Why do the people imagine a vain thing? (Psalm 2).
Furthermore, you would have us believe that what we read in the Bible in relation to the movement of the stars, sun, and moon has to be understood in phenomenological language. This is a fancy way of saying that the Bible does not mean what it says and that God has not, or cannot, clearly articulate his creation. This casts doubt on God’s Word and echoes the first words of the serpent: “Yea, hath God said...? (Gen. 3)” – That old serpent called the Devil, and Satan which deceiveth the whole world (Rev. 12). In essence, your article gives more credence to the lies of Satan than the truth of God’s Word.
Your article dares to affirm that the burden of proof lies with Geocentricism (stationary earth). Geokinetic theory evolves to give an appearance of credibility to lie upon lie whereas Geocentricism is centred on the truth of God’s Word. There may be no turning back for you and your colleagues at CMI. God is gracious and full of mercy. He gives space to repent but His judgment is quick.
Let the interested reader note that this person believes the universe is a grand illusion and that the Christians involved in NASA are rotten, filthy liars in league with the Devil himself. We have one bonafide rocket scientist on staff, other speakers who work or worked with the aerospace industry, have interviewed more than one physicist in Creation magazine, and listed multiple people who called on the name of Christ for the salvation in our article. All of these men are deceived, at best.
As far as phenomenological language is concerned, we see it at various points in the Bible. God is not, actually, an "all consuming fire", etc. If we are to talk about the "truth" of God's word, we first have to decide what the language means. Taking a straightforward approach is not the same thing as taking a literalistic approach.
Let the reader also note that we wait patiently for the "quick" judgment of God. It is a humbling thing to know that we will one day be judged and can only plead the Blood of Christ in our defense. Maranatha!
In the Jan-Feb (1977) issue of Bible-Science Newsletter, an article was published challenging a Geocentric believer (Gerardus Bouw?) to refute his article. He stated that in order for a stable orbit to be maintained, the mutual gravitational force must be perfectly offset by the orbiting body’s centrifugal force. He set up the equation and found that the orbital period was equal to 2(pi) times the radius taken to the 3/2 power all divided by the square root of the Universal Gravitational Constant times the mass of the stationary object. If the earth was in the center, it would take thee sun 211226.9 days to complete one orbit. Sun centered, it would take the earth 365.8 days, just as we see today. I never saw an answer to the article. I have the math if anyone's interested.
Of course, at the given earth-sun distance and with a mutual gravitational attraction as calculated by Newtons Law of Gravity, the sun must be moving very slowly to prevent it from flying away from us. But this is assuming the Law of Gravity is applicable. Geocentrists reject it, so the argument dies on the vine. They do not appeal to known physics and do not accept the introduction of physics into the discussion unless it suits them.
Drs. Carter and Safarti: Some of the evidence you present in this article against absolute geocentrism will need to be reconciled with your YEC earth age. Your YEC earth age is approximately 6,000 years. However, given the distance from earth to distant stars, or the distance between stars and galaxies, as you state in the article, would it not take longer than 6,000 years for the light to travel those great distances?
You need to consult our Astronomy and Astrophysics Q&A page, specifically articles under the heading How can we see light from stars millions of light years away?
I feel you are being too charitable here.
Jesus cautioned us to "know them by their fruits." When Hugh Ross used outright lies and deceptions to make his points as CMI has caught him doing; benignly embracing of him as a Christian Brother in spite of all that is not even the best thing for him compared to calling out the apparent source for his self deception.
Jesus did indeed warn us to "judge not" lest we be judged, but the Bible also tells us that we have the sober responsibility TO judge! In that context, we are reminded that we will even be responsible for judging the angels!
When Jesus turned to Peter and said "Get thee behind me Satan" he wasn't consigning Peter to the pit of Hell forever. But He was telling him in no uncertain terms that he was being used as a tool of the Devil in at least that instance.
The forces of Hell are much more arrayed against you and CMi's ministry than they are against a ministry that has a message that undermines the Gospel. I sense that the current crop of geocentrists are on the same team as the outspoken old Earth Christians. Satan likely has little objection to their message receiving a lot of play.
We are getting called all sorts of names from that side; I am not of a mind to hurl the invective back at them. In light of 1 Pet 3:15, we are called to answer humbly. Let the reader judge the merits of our answers.
I will also take this opportunity to note once again: No detractor has attempted to seriously grapple with our list of evidences against geocentrism. "The Bible says..." and "These experiments prove..." have been the only answers, but we dealt with both of these areas in the article and preceding comments.
Genesis 1:16 - 19
If the Earth revolves around the sun, what did it revolve around for the first 3 days of creation? If it was still for the first 3 days and God set it in motion about the (presumably larger) sun after He created this on the 4th, would that not be an act worth noting? The bible is as clear that the Earth doesn’t move, as it is that God didn’t use evolution to create.
I understand that science also disproves a moving Earth, unless one can accept such contradictory (non-science) theories as Einstein’s General/Special Relativity, and Lorenz-contraction (experimental apparatus shrinking during the experiment). Such are excuses to explain away the logical conclusions of experimental results, similar to many evolutionary “theories”.
The most basic proof that the Earth does not move is that you cannot feel it. Were we really spinning about the sun due to gravity, we (the Earth) would be constantly accelerating toward the sun. Whenever one undergoes centripetal acceleration, one can feel it. This is different to a constant linear velocity (say, in a car), and is better likened to a car speeding about a circular track. The constant acceleration of the car toward the center point of its circular path would be experienced by any passenger or driver (despite a constant speed), unlike the case were the velocity constant (i.e. speed constant in a single linear direction).
The pathway to evolution (to make respectable the rejection of Christ) could not have occurred, had the Earth’s central position in God’s Creation not first been displaced in the eyes of men.
Thank you for the article. We disagree now, but many Christians are coming to realise we have been lied to, and are starting to return to the infallible words of the only wise God our Saviour. God bless you
If the earth were not spinning, why would there be 'day and night'? Was there an orbiting light source NOT called the sun prior to day 4? Or was the universe pulsing with light for those first couple of days? Either way, the language becomes strained if not a rotating earth. But, as we said in the article, once the earth rotates there is no reason to hold to a geocentric universe.
You understand the science disproves a moving earth? Then you did not read the list of evidences we provided at the end.
You cannot feel the earth rotating? One word: hurricanes. Also, did you not see that we directly answered this claim in the article? "At the equator, there is a reduction in apparent surface gravity of ½ of 1% compared to the poles. 70% of that is due to the ‘centrifugal force’ counteracting the attractive force of gravity. The remainder is due to the difference in distance from the center of the earth caused by the bulge." This reduction in the force of gravity is exactly what one would expect based on the difference in distance to the center of the earth between the poles and the equator + a 1000 mph tangential rotational speed a the equator.
Ah, but you are not talking about the earth rotating. You are talking about the earth orbiting the sun. Have you considered the degree of curvature of that orbit? On small scales (i.e. that which we could 'feel') it approximates a straight line. Also, the distance from the near side of the earth to the far side of the earth is negligible compared to the distance of the earth to the sun. Thus, there is no 'feel' here either.
As I said in other comments, it did not take geokinetics to displace God. Most ancient cultures were geocentrist and most rejected God. True, there is, in the Western world, a series of events that led from theism to atheism, but it was not science but scientism that caused this.
Yes, we disagree, but we are at least encouraged that more and more Christians are coming to realize the sensible nature of the universe comports to the divine attributes of God himself and that we do not have to reject simple, observational, operational science if we want to hold to the divine inspiration of Scripture.
Very informative! You marshall a lot of arguments to make your point.
I'm wondering whether Foucault's pendulum experiments apply here as well. I understand that these also can be readily explained by a geokinetic model but would involve a miracle in the geostationary view of the cosmos.
Presumably it's not a real miracle if we can produce it whenever we like.
There are always geocentrist counter arguments to the best geokinetic evidence, but most of them make no sense. One deals with the spinning universe producing an 'advanced signal', meaning the pendulum can sense what the universe will do in the future. It is not my intention of discussing the counter arguments at length, but let this serve as an example. The simple observation that all objects in the universe are attracting each other explains even Foucalt's pendulum. The geocentrist assumption that the earth is unmoving at the center of the universe requires a different explanation for each phenomenon, and many of these explanations are nothing if not mysterious.
Thanks for your answer re: revolving/orbiting (and rotating). I read the "morning-has-broken-but-when" article, and it doesn't actually touch nor resolve this issue: if the premise is that on days 1-3 the observable universe was not as we know it today, and the universe is finite, how (or, really, why?) from the text should we infer that one of those days God made the earth start revolving around the sun? Was it at the "separation of the waters?" Why is it less plausible that the whole thing looks like a giant whirling snow globe (or fish bowl) with the earth at it's centre? If it's not so hard to believe that all the stars were made on the same day, after the plants, then couldn't your proposal that, "God could easily have moved every atom in the earth at the same time" be just as easily applied the other way: God moved every atom around the earth? There's evidence for both, right? Both "scientifically" and mathematically, right? If one's faith is strong enough for a literal creation week, against the wisdom of this age, why would it not be for a God-sized mind-blowing geo-centric view? Just wondering. May you and all y'all at CMI be blessed in your vital ministry.
God 'moving every atom on earth at the same time' as part of creation week is not the same thing as God 'moving every atom in the universe around the earth' today. One deals with fiat creation. The other deals with ongoing processes. The first is not scientifically testable. The latter requires experimental science to be flat out wrong. Is there evidence for geocentrism? Yes, but you have to include ALL the evidence. Naked-eye astronomy appears to show that the universe revolves around the earth, but Newtonian physics says otherwise. The only way to combine these two is to conclude that naked-eye astronomy only gives us an appearance that is based on an earth-centric reference frame.
What a well reasoned and scholarly treatment this article is. I am blown away by you guys continually but this article is a fresh reminder of why I love CMI.
But when I got to the comments section, it was quite an eye opener. Although I was familiar with Hugh Ross and the valiant fight CMI wages against his sort of Christian Old-Earth silliness; now I see that the enemy is waging a similar war on other fronts as well. It seems that Satan's objectives are to oppose the Gospel by sowing confusion and depicting Christians as fools.
You just exposed that depiction as false; keep up your excellent work!
As I said in a comment just above, let us be careful not to insult our fellow brothers and sisters in Christ. Certainly, sowing discord among us in an effective tactic used by the opposition, but that does not mean geocentrists (or us!) are tools of Satan. Of course, you don't believe this, but someone from the other side might take your words in a different way.
Thank you for this fascinating article. Very enlightening.
Have you seen promotions of a new movie hitting theaters (albeit limited) called "The Principle." It looks interesting, in that it claims to thoroughly refute Copernican principle and that there is strong evidence that the earth is at or near the center. [URL removed as per site rules]
p.s. I see that Dr. Hartnett is interviewed for the movie, so I assume you are aware of it. Thoughts?
Oh yes, we are aware of it. In fact, it was one of the catalysts that led to this article. With full approval from Dr. Hartnett, we decided to nip this in the bud. The movie takes an absolute geocentric position. He does not. Neither do we. If you see it, watch for how they craft his words and see if what he says comports to what he believes. See also his review on his personal website: The Cosmological Principle and geocentrism.
Superstition and pseudoscience rule..always has and always will...PT Barnum knew it and used it to make millions. Bottom line IGNORANCE is a bigger business than the "first business."
Careful, David, these are our brothers and sisters in Christ and we do not want to insult them for any belief they hold close to their hearts. Non-Christian ideas should be pointed out and vigorously opposed, but geocentrism vs. geokinetics is something that begs for frank, give-and-take discussion, not insults.
There is no way around it Robert, The author of The Bible (God) was a Geocentrist and a Young Earth Creationist if Geocentricity is false and/or Young Earth Creation is false then The Bible is wrong and God was wrong and if God that cannot lie was wrong then neither can The Gospel be trusted.
Paul put that much forth in 1 Cor chapter 15 since our Faith is based on objective truths not subjective religious beliefs our faith is falsifiable.
17And if Christ be not raised, your faith is vain; ye are yet in your sins. 18Then they also which are fallen asleep in Christ are perished. 19If in this life only we have hope in Christ, we are of all men most miserable. 1 Corinthians 15:17-19
The thing is, if Airy's failure, Michelson-Morley Experiment Sagnac Experiment and Michelson Gale Experiment had been done (able to) back in 1620 or so The whole Copernican Principle would have been deemed falsified by those science experimeny results and then Everybody today would be a Geocentrist and Billions of Years/millions of years and Evolution would never had even become an issue and CMI probably would not have any need to exist.
I get ridicule for all 3 of views but I believe if any are proven wrong then Christianity is false.
King James Bible believer Pure Cambridge Edition PCE 1900. If that's not the inerrant infallible word of God preserved by God in 2015 then there is no inerrant infallible word of God preserved by God in any language to be the final authority. There is no The Greek text or "The Hebrew text" There are many of each that differ
If Young Earth Creation is false then The Bible is wrong and the Gospel in it cannot be trusted.
If Geocentricity is false, then The Bible is wrong and The Gospel ???
Brian, this is comment #4. Please understand that this is not a blog site. Neither is it a convenient place to hash out a difficult argument. Neither are we obliged to answer or post every comment made by every person. Therefore, I get the last word.
1) You have gone from empirical arguments for and against geocentrism to King James Onlyism. Thus, your argument has gotten convoluted. The discussion has almost nothing to do with Bible translations.
2) Yes, if those experiments had been done earlier, they would have affected the course of scientific discovery, but why would they run the experiments before the issue came up? And, even if delayed, science would eventually have caught up to what we know today because somebody would have eventually sent a rocket into outer space and noticed that it did not behave the way they expected.
3) You do not need Copernicus to have billions of years. Ask any Hindu.
4) This argument has nothing to do with the King James Bible, because every modern translation uses similar phraseology in the relevant passages, with the lone exception being "firmament" in Gen 1:6. If your only argument is "firmament", you do not have much an an argument. We discussed this, and the other passages, in the article.
5) I am very sorry that you believe that if geocentrism is proven false your Christianity is also false. I am not of that persuasion. Neither is anybody at CMI. This is an issue of 'where do we draw the line', and, as I said in a comment above, that line is between operational and historical science. Operational science works among the planets. Yet, it cannot if geocentrism is true.
6) Thank you for the candid discussion. Thank you also for educating us about your views. Frankly, we were surprised, yet you are probably not the only one out there, so this discussion is of some benefit.
7) We note that even after all these comments have been made, not one person has attempted to address our main arguments. Instead, they have fallen back on sweeping statements about the 'big' experiments that supposedly proved geokinetics wrong (but that are actually equivocal) or sweeping statements about biblical language ('the Bible says it, therefore I believe it') without addressing the phenomenological aspects of communication.
Good study. However, we could be the relative center of the universe, not the actual pinpoint. Hubble discovered evidence of our centrality in his studies of the expansion and the discovery of the red shift. However, he let atheism dictate his position simply to nullify the possibility that we were central, a fact he thought would prove God's existence. He decided on the assumption of uniformity: he said: “The assumption of uniformity has much to be said in its favour. If the distribution were not uniform, it would either increase with distance, or decrease. But we would not expect to find a distribution in which the density increases with distance, symmetrically in all directions. Such a condition would imply that we occupy a unique position in the universe, analogous, in a sense, to the ancient conception of a central earth. The hypothesis cannot be disproved but it is unwelcome and would be accepted only as a last resort in order to save the phenomena. Therefore, we disregard this possibility and consider the alternative, namely, a distribution which thins out with distance."
You are correct. See a comment above with links to articles that discuss the relationship of the earth to the universe in general.
This article did not need to be so long to answer the simple question: is the earth at the center of the universe?.
Here are the facts available to a non-scientific reader: (a) the observable universe (what we know about) is about 93 billion light years in diameter; (b) the Virgo Supercluster containing the Milky Way is in the center of the observable universe; (c) the Earth is part of the Milky Way galaxy and therefore is also in the center of the observable universe.
(Keep in mind that the dimensions of the observable universe are so large that when we say the earth, the Milky Way Galaxy or the Virgo Supercluster are at the center of the Universe we don't quite know where the Center really is, but we're close enough to satisfy the "naked eye"!)
There...wasn't that easy? But hey, you don't have to take my word for it. Check it our for yourself, and have an astronomically nice day: [link deleted, as per site rules]
Also, see Our galaxy is the centre of the universe, ‘quantized’ redshifts show and Our galaxy—at the center of the universe after all! and other articles on creation.com, at least one of which was mentioned in a comment above.
Good article. The second paragraph is interesting because you say (and I agree) that naturalism works today. That is, I can do an experiment and try to figure out the laws of physics, confident that these laws are consistent and reproducible. However, you also say that there were supernatural events in the past that created the universe, and other supernatural events such as Joshua's Long Day. Anyone witnessing these supernatural events would not be able to determine any laws of physics from them and would not be able to reproduce them. In fact, they would see these supposed "laws" broken and lose their faith in naturalism entirely. I wonder at what point in time naturalism became valid. When did supernatural causes cease?
Great question. The answer is after "God rested from his labors" (Gen 2:2). Please see Miracles and Science, and the DVD titled Are Miracles Scientific (same link).
Why doesn't CMI discuss Airy's failure, Michelson Morley Experiment Sagnac Experiment and Michelson Gale Experiment?
Why does CMI discuss Gallieo, and Copernicus Ptolemy but never present The Neo Tychonic Cosmos (Updated Tycho Brahe model)?
I think that CMI though willing to take the heat from Evolutionists are not willing to take the heat they would take from EVERYBODY if they took a Biblical stand on Geocentricity.
Considering Kids from age 5 up are indoctrinated into The Copernican Principle , Billions of years and Macro Evolution for CMI to skip over The Copernican Principle and then try to star the fight at the age of Earth an
d Evolution is missing the foundation of it all.
People are taught to believe it is "common sense" that the Earth is spinning 1,000+ MPH at equator and hurling through space at approx. 66,000+ mph. They have no clue why they are supposed to believe that but accept it just like they accept billions of years and evolution (macro).
Airy's failure, Michelson Morley Experiment Sagnac Experiment and Michelson Gale Experiment as demonstrated by Malcolm Bowden show that the denial of Geocentricity is the foundation of Satan's deception that directly led to billions of years and Macro Evolution.
.. that old serpent, called the Devil, and Satan, which deceiveth the whole world."
If people were to realize the Earth is stationary center mass of entire universe then they would have to acknowledge the One who put it there and acknowledge that He put it there approximately 6,000 years ago with no macro evolution in there anywhere at all.
I understand people can argue flat Earth from Bible as well as Sphere Earth though 281 Geocentric references are too many 2 ignore
Simply refer to our answers to the previous comments. All of this has already been discussed.
If Geocentricity and YEC is wrong then The Bible is wrong.
These two things are not the same. Note our comment about the "ministerial" use of science (here used to flesh out ambiguous passages) vs. the "magisterial" use of science (as old-age evolution does invariably when it trumps the biblical timeline). "It is the glory of God to conceal things, but the glory of kings is to search things out" (Pro 25:2, ESV). The relationship between the earth and the heavens was concealed for a very long time, but that is no longer the case. If the physical universe is knowable, rational, and consistent (all three of these tenets are derived from Christian theology, btw), geocentrism fails. But this does NOT mean that YEC fails, that the Bible is not inspired, etc. One does not have to let go of the doctrine of inspiration to let go of the earth. Far it, in fact. One must draw the line somewhere, but the line is between historical vs. operational science, not within operational science.
This topic is where CMI like [another creationist organization] fail to be biblical and actually CMI and [another creationist organization] treat Geocentrists
the way that the atheist Evolutionists treat CMI and [another creationist organization].

[note this comment was edited to remove URLs, as per site rules, and references to other creation organizations and speakers outside CMI] 1) We are accused of failing to be biblical, but the accusation is falling flat in reference to our Statement of Belief. 2) We are accused of treating geocentrists unfairly, but where is the evidence for this in this article? It is unfair to bring up personal history we cannot defend against in this format. 3) How can we stand for the authority of the Bible in light of the many uses of phenomenological language in the Bible? See our discussion. 4) Sermons are preached on all sorts of things, and you and we would consider the contents of many to be heretical. So what if some are preached on geocentrism? I just read a story about a Islamic scholar who teaches geocentrism. That also means nothing. 5) We discuss the neo-tychonic model in the article, and why it fails. The other experiments were discussed in a reply to a comment above. And let's not confuse absolute geocentrism with the the relative position of the earth in the universe. CMB, PLANK, and WMAP all indicate we are either near the center of a spherically symmetric universe, or the data are corrupt, as recent claims against the BICEP2 results would indicate. 6) How can a Bible believing Christian read the Bible and not be a geocentrist? Reading the Bible certainly does not automatically make one a geocentrist. The opposite is true, in fact, as attested by the fact that the majority of conservative Bible believers are not. How can a Bible believer read those books and not be a geocentrist? Read the article and the replies to these many comments.
Great article, clearly loads of good solid research. Wondering about all this and how it fits into the 6 day chronology of Genesis 1, I would like to ask: what was the Earth rotating around for days 1, 2, & 3 if the Sun wasn't created until Day 4? Asked another way, which model better fits a literal Genesis account?
I think you mean "revolving/orbiting" not "rotating". In the geokinetic model, the earth was simply spinning in space and gravitational motion relative to the sun would have begun when the sun was created. Would this have cause the earth to "jerk" forward? Not according to the physics involved in Joshua's long day (God knows the physics required and can account for all parameters), and God could easily have moved every atom in the earth at the same time, or the earth and sun could have been created with the correct relative motion to the other to avoid any jarring. Which model better fits a "literal" interpretation? The one that can account for both the text and the physics without forcing an interpretation on one or the other. See Light before the sun?.
I am greatly surprised that a very lengthy article on geocentrism NEVER mentions the four main SECULAR experiments that all point to a Geocentric universe.
(1) Michelson Morley - showed that we were NOT going round the Sun at 30km/s. This shook the scientific world and they rushed out the Fitzgerald-Lorentz Contraction to "explain it away".
(2) The Michelson-Gale experiment that showed an aether was passing across the surface of the earth within 2% of 1/day - either the earth was turning OR the aether was rotating around us.
(3) Airey's "Failure" showed that it was the aether rotating around US. The Earth was stationary.
(4) Sagnac's experiment demonstrated that the aether existed. To overcome the M-M Exp, Einstein produced Relativity which abolished the aether. Thus Sagnac disproved Relativity.
Barbour and Bertotti showed that the geocentric universe was perfectly viable, as did Popov.
This article cherry-picked all the evidence against Geocentrism and completely ignored the SCIENTIFIC evidence that supports it!
I have about 8 YouTube videos on Geocentricity.
Would you allow a reply article?
1) M-M was equivocal. Either the earth is not spinning or light speed is constant in every direction. 2) M-G is equivocal, as you said. 3) Airy's experiment is equivocal, and trivial as far as Relativity is concerned, as I discussed in an earlier comment. 4) Sagnac's experiment was equivocal, and is consistent with Relativity, as von Laue showed two years prior to Sagnac. You're right, we did not discuss these. Perhaps we need an addendum to explain why the main things used to support geocentrism are all equivocal. The careful reader will note that we sought to bring up unequivocal evidence in support of geokinetics.
I find a real double standard between taking a literal 6 days of creation and the geocentric debate. Who is creation.com to decide what the Holy Spirit meant?
What about Joshua's long day?
As others have mentioned, all the arguments provided against geocentrism can be refuted, why on this issue is science 'so-called' taken to over ride the plain reading of scripture?
Did you actually read the article? We discussed Joshua's long day and other things. "Who are we"? Nobody, actually. We are not some holy authority, lording it over others, and we are not deciding anything for anybody. How could you get that out of what we wrote? And, as many others did, you fail to bring up substantive arguments and instead resort to the catch-all "all the arguments against geocentrism can be refuted". So, your entire argument boils down to the "plain" reading of scripture. God said it, that settles it? You must address what God actually said and put that into common language conventions. Our outline should help.
To be succinct, you have missed every point entirely because of not doing your homework. I strongly suggest that you begin by reading
" GEOCENTRICITY : CHRISTIANITY IN THE WOODSHED " " SUN, STAND THOU STILL " by Henry Schuman Inc. also published as " THE WORLD OF COPERNICUS " Also, it is instructive to see the following video : Nova: Season 30, Episode 4 Galileo's Battle for the Heavens (29 Oct. 2002) and........ GALILEO'S DAUGHTER by PENGUIN BOOKS. Having 20 years working inside NASA Science, I can tell you that Romans 1:18-19 is truer than you can imagine. Many NASA scientist secretly agree, but would lose everything ( materially and family ) if they acknowledged it.
Your article is woefully incomplete.
[note: this comment was edited prior to publication to remove URLs, as per site rules, and to clean up some formatting issues] Clearly, we did not win over every reader. However, all this is is elephant hurling. You have provided nothing substantive to answer. You say "many" NASA scientists are, what, geocentrists? I seriously doubt that "many" are, but so what?
The detail in your article is appreciated however...
K-I-S-S....RELATIVITY. No wonder Galileo Galilei hedged his bets!
Due to the nature of the arguments, we had to do more than just discuss relativity. I hope you can see that.
The bible is not a book about science but where it touches on science it is always correct, if you accept that it is God's word then you would expect nothing less. The creation sequence as stated in Genesis in detailed in such a way that theories like evolution are automatically excluded. In a similar way the bible portrays a geocentric universe, if read in a plain straightforward way it excludes heliocentric ideas. The earth is at the heart and centre of the universe, the centre of God's attention. Helocentricity detracts from this and gives the evolutionist the excuse that the earth is just another planet, one of many.
The bible also describes the purpose or function of the universe, that is its supporting role, the stars are for signs and seasons and declare the glory of God, the sun to rule the day and the moon to rule the night etc. The earth also has foundations so that it can never be shaken or moved. There is no scientific reason to compel us to believe anything different.
Observations of the movements of stars, planets and questions of parallax can be explained by both models but experimental evidence carried out in the past would support a stationary non spinning earth with a rotating incredibly dense aether. The Michelson Morley is one such experiment the results of which indicated that the earth is not moving. There are problems with a spinning earth, the effect it would have on the atmosphere for instance.
Nothing in creation is simple, rather creation shows an incredible complexity, for example the so called simple cell. The more we find out about God's design the more we marvel at the sophistication and elegance of His solutions to design problems. The geocentric model fits the bible very well.
You have broached multiple topics and space is limited, but I must reply to some. 1) Your opening comments are spot on. 2) The Bible does NOT portray a geocentric universe. All descriptions are phenomenological or conventional, as we discuss in the article. 3) Yes, the earth is at the heart of creation, but this does not mean it is at the physical center of creation. You are extrapolating from the spiritual to the physical. 4) The evidence for extrasolar planets is mounting steadily. There is no reason for God to NOT create other planets around other stars (this does not mean life is out there, but that is yet another topic). Thus, geocentrism does not have the upper hand here, for those planets exist no matter the physical explanation of the universe. Or do we have to reject this data as well? 5) The stars etc. as signs for the seasons has nothing do do with our relative motion in respect to those things. 6) The earth can never be shaken -- now I am thinking you did not read the article! 7) We outlined a great deal of experimental evidence that supports geokinetic theory. M-M was equivocal and the purpose was to contrast two opposing theories of aether more than it was to decide geocentrism vs. geokineticism. 8) Nothing in creation is simple, so why hold to the 'simple' geocentric theory? As you just said, complexity is no reason to reject any aspect of creation.
I love your site, but I seem to be a lone objector on this one! I have researched geocentrism, and convinced of it scripturally, and pardon me by saying I have a 'gut feeling' that it is the truth. It has been said that the devil could not have gotten evolution rolling without first setting up Copernicus and the heliocentric idea.
I think that if you were to give geocentrism even a breath of consideration, the howls you now get from a large portion of the Christian community for your stand on a YE 6-day creation (which I firmly believe) will seem like whimpers!
'Gut' feelings are not good arguments. When emotions conflict with observation, one of them is generally wrong. And, evolutionary ideas were found among the Greek philosophers, most of whom were geocentrists, so Copernicus was not needed for evolution. Instead, Copernicus was a leading figure in the Scientific Revolution, which was an outgrowth of Christian appeals to the use of logic in theology. It was the detour to atheistic 'scientism' during the Enlightenment (at the hands of those who hated the then religious underpinnings of science) that is to blame. And, as our track record certainly shows, we are not afraid of reprobation from even the Christian community. We took this stand on this issue because we feel it was the correct stand to take. Thus, there is no reason to give geocentrism even a breath of consideration.
I'm surprised that you didn't mention the recent book by Dr Hartnett "Starlight Time and the New Physics". He shows that a development of the Cosmic Special Relativity of Moshe Carmeli fits/explains the observable astronomical data well and does away with the need for dark matter and dark energy. I've forgotten too much maths to fully follow his arguments, but his conclusions are persuasive. Sadly atheists will cling to the cosmological principle which requires there to be no centre to the universe despite contradictory data.
See footnote #52.
The difficulty for me, is why there are no scientific experiments showing the forward movement of our earth. Airey's experiment seems to prove our earth is stationary. Should we not reason from the general to the particular. I want to believe you are correct, because I mentioned my Geocentrism to a few people, and now am facing religious persecution. I am so tired of being a misfit.
But if the earth is not moving, Neptune is moving at nearly light speed. We have sent space probes past Neptune, but we do not have the ability to accelerate objects to faster-than-light speed. What other proof is needed? Earth and Neptune are both moving through space at orbital speeds predicted by Newtonian mechanics. Most experiments designed to test if the earth is moving were equivocal. "Type A" experiments can decide between two hypothesis, depending on the outcome. These are the ideal experiments. "Type B" experiments can decide between hypotheses if the outcome goes in one direction but cannot decide between them if the outcome goes in the other direction. These are very common in science. "Type C" experiments cannot decide between hypotheses no matter what happens. In a paper titled "Airy's Water Telescope" (The Observatory 60:103-107, 1937), the editors stated, "In Relativity theory, Airy's experiment is trivial, as the observer is at rest relative to the telescope." Thus, Airy's experiment was a Type C. It tells us nothing for both hypotheses predict no aberration. There is nothing wrong with being a misfit, with standing one's ground on biblical ideas, but let us pick the right battles.
I have often been impressed with the intellect God has given to Jonathon Sarfati and the others at CMI. Congratulations on a very thorough refutation. My first thought was why put so much effort into refuting something very few people actually believe? A quick internet search revealed that perhaps there are more absolute geocentrists out there than I realized. Unfortunately, it appears that many are basing their arguments on Biblical terminology, thus creating a possible point of contention among Bible believers. It seems as though the enemy of our souls will use anything he can to discredit God’s Word and get our focus off of the truth. Keep up the good work, and may God bless your efforts at disseminating truth with humility.
We did not write this article only to rebut a minority position. It was also a chance to extol the great men who went before us, teach about applied logic, discuss one of the greatest scientific mysteries of the ages, and marvel at the universe we have under our feet and above our heads. There are so many threads wrapped up in this story that it is nothing short of amazing. Thus, the joy of writing was also one of our motivators. Thanks for the kudos.
Almost every Biblical verse says the sun is moving or standing still. God could just as easily have said we are moving.
Of course, but the Bible is also not written to be a comprehensive science book. It is a book of history that focuses on the story of the Bride of Christ. God could have said a lot of things about all sorts of scientific issues that are not fleshed out in the text. And the sun IS moving in an earth-based reference frame, so there are no textual problems here. We dealt with this at length in the article.
I have never seen such a lengthy article on creation.com, which implies this much energy has never been spent on any other topic.
This is quite disappointing as, I believe with some extra research, one would’ve found that each and every point made in this article has been properly refuted already. Conveniently, they've also been packaged up neatly into a book, Geocentricity: Christianity in the Woodshed, published last year and authored by Gerardus D. Bouw, PhD (Astronomy).
The reason I feel this book is important, to this article in particular, is because in footnote 70 the article authors admit Bouw is “probably the best known geocentrist today”, however the only other footnote regarding his work is one where he coins the term ‘geocentricity’. All other arguments in the article are refuting arguments of someone less preeminent in this field, if at all. I find that odd, but it is the reason I feel Bouw’s book covering every aspect of this article is essential reading.
Note: this comment was modified prior to its publication. One hyperlink was deleted as per site rules and the several personal comments were removed. And, although this person made a generous offer to supply interested people with the book he mentioned, this is simply inappropriate for a place like this. Readers who are interested in the subject can find such information offsite. We trust that, after carefully reading this article, the arguments from the small geocentric community will not be convincing.
Concerning our rationale, it was not necessary to list and attempt to refute every argument made by modern geocentrists. Instead, we took a positive approach, built up our case carefully, and applied the best available scientific evidence to the problem. The burden of evidence is squarely on the shoulders of the other side, yet I note that not one example of how our points have already been ‘refuted’ was provided. Of course, a comment box like this is not a place where these things can be debated. While we appreciate your heart for the subject, it would have helped to have at least one point made instead of the ‘elephant hurling’ tactic of dismissing all points in one fell swoop without citing any actual evidence.
This is an interesting and informative article. One thing that I would like to point out, however, is that nothing therein constitutes an argument against the thesis that the earth is, approximately, at the center of the universe. That thesis and the thesis that ‘everything revolves around the earth’ need to be kept clearly separate in discussing these matters. Like isotropy and homogeneity (the so-called Cosmological Principle, the thesis that the earth is, approximately, at the center of the universe belongs to the realm of metaphysical assumptions or speculations rather than that of empirical science.
You are 100% correct, we did not discuss possible position of the earth in the universe. However, there are several articles on creation.com that discuss this matter. Start here: Where are we in the universe?
This is a really interesting article, and almost certainly the most thorough anti-geocentric treatment which has yet been penned by genuine Christians with a complete fidelity to God’s Word. Until now, the lengthiest which we had was Danny Faulkner's article from 1999, which—I think—unsuccessfully attempted to address the claims of Gerhardus Bouw. Having read both sides, it was firmly my opinion that Dr. Bouw had the better of that exchange. I never quite accepted geocentricity, because—even though I had not examined the issues in anywhere near such depth as they are presented here—it always struck me as requiring too much of what I call non-regular God-force, even though—as this article freely acknowledges, which I think is very important—it IS possible to construct models which fit the observations. After reading this piece, I can begin to appreciate just how much physics has to be rewritten in order for geocentricity to work.
I particularly like the emphasis on how, on many occasions, the Seventeenth-Century geocentrists were often more scientific than those who opposed them!
One thing which I might suggest as an addition—though I know this is already much lengthier than the vast majority of CMI articles—is a handful of diagrams to show the various models. I know what many of them look like because I've read quite a bit on this matter before, but for those who are entirely new to it, diagrams of Ptolemaic, original Copernican, original Tychonic, modern acentric (secular cosmology), modern geocentric, modern galactocentric (CMI’s favoured model), etc. models I think would greatly aid conception.
Whether you choose to add these or not though—a very fine overview indeed. My compliments to Dr. Sarfati and Dr. Carter.
You picked up the main point of the article: “I can begin to appreciate just how much physics has to be rewritten in order for geocentricity to work.” Thank you for the compliments and, as far as extra diagrams go, that is always a possibility …
