Our young solar system
Accepted theories of evolutionary science say our Earth and our solar system formed about 4.6 billion years ago. On the other hand, the Bible implies Earth is only several thousand years old. Further, Genesis 1 and other passages such as Exodus 20:11 imply that everything in the physical universe was created in the six-day Creation week. Thus, like Earth, the solar system also is only thousands of years in age. Is there scientific evidence that our solar system is not billions of years old? Yes! And this evidence is posing a mystery for scientists who believe in billions of years.
Evolutionary theories propose that our solar system formed from a large spinning nebula in space.1
The nebula is believed to have flattened to a spinning disk of gas, dust, and ice known as the accretion disk. Over millions of years, gravity caused the planets and other objects to form from this disk, and then excess gas and dust dissipated and cleared away, leaving the solar system as we see it.
An important concept in this origins model is that all objects in our solar system, which are bound by gravity to our Sun, were made from the material in this original nebula. So, this nebula becomes the common source from which everything in our solar system formed.
However, this long-age view of our solar system involves many scientific problems, which can be listed in three categories, namely chemical change problems, heat problems, and dynamics problems.
Methane not missing
One of the chemical-change problems for long-age thinking is the presence of methane on Titan, a moon of Saturn. Titan has an atmosphere thicker than that of Earth, made up of nitrogen and a long list of organic gases, such as methane, ethane, acetylene, and others. After much study of Titan’s atmosphere and the recent Cassini mission probe landing on its surface, an interesting mystery remains.
Scientists modelling Titan’s atmosphere have calculated that it should contain no methane but should have been used up in tens of millions of years.2 That’s because many chemical reactions use up methane in Titan’s atmosphere.3 Although there is some replenishment with methane evaporating off Titan’s surface this is not enough to solve the problem. In fact, there is probably also methane escaping Titan’s atmosphere into space,4,5 which would mean that Titan’s calculated upper limit ‘age’ could be even younger than 10 million years. Clearly this is contrary to the billions-of-years age for the solar system. On the other hand, such evidences of youth are expected for a solar system of biblical age.
Another chemical problem, one involving the Sun, is summarized in a recent headline, “Sun and planets constructed differently than thought, NASA mission suggests.”6 In particular, the Sun has a different composition from Earth: much more oxygen-16 and much less nitrogen-14. A writer in Science, commented, “The principal conclusion from the studies … is that the Earth was not constructed from average solar system materials.”7
The young Sun was too cool
An example of a heat problem for long-age thinking that affects Earth and the Sun is usually known as the faint young Sun paradox. Evolutionists believe the first living cell formed from chemicals on the early Earth about 3.8 billion years ago. At that time in the Sun’s life cycle it would have given off about 30% less light energy than today,8,9 and the Earth would have been much colder. Earth would likely have looked like a ball of ice instead of how it looks today. Thus life would not be likely to survive or evolve.
But this problem disappears when we interpret the evidence from a biblical perspective. In this view, the Sun was created essentially as it is today, and would not have changed much in 6,000 years. Thus God created the Sun with properties well suited to our needs, and it has been a very stable source of energy for us and for all life on Earth.
Io is too hot
A different type of heat problem occurs on a moon of Jupiter called Io. Jupiter is about five times as far from the Sun as Earth is, and has a mass of over 300 Earths. Io has various forms of sulfur across its surface and many volcanoes that are much more active than Earth’s volcanoes. The quantity of heat given off by the volcanoes on Io is much more than on Earth per unit of surface area.
Though scientists expected Io to be volcanic, the amount of heat coming from Io has been surprising. Consequently they have tried to explain the interior of Io and the amount of heat generated by all the volcanoes.
Jupiter is at least part of the cause of Io’s heat. Because Io has an elliptical orbit around Jupiter, and Jupiter is so large, massive tidal forces due to gravity squeeze Io and cause its shape to oscillate, generating heat inside Io—a process scientists call ‘tidal dissipation’. However, the amount of heat that Io gives off, that scientists have observed with infrared telescopes and spacecraft, is about 10 times the amount of heat generated by all known sources of heat, including tidal dissipation.10 The heat problem remains for the billion-year explanation.
However, the geology of Io is easy to explain when we assume there is heat left over from its creation and that Io is young. The processes proposed by scientists to explain Io are implausible over long time scales because they cannot continue the same way for billions of years. However the processes work well if the heat present after Io’s creation is simply used up and dissipates over several thousand years.
An example of a dynamics problem for long-age thinking concerns short-period comets, which orbit the Sun in elliptical paths. As they come near the Sun, comets lose material into space and give off a ‘tail’ called a coma that makes them beautiful to see. Short-period comets make an entire orbit in less than 200 years but long-period comets take more than 200 years.
Planetary scientists believe that long-period comets come from a hypothetical region far from the Sun called the Oort Cloud. Shaped like a spherical shell, the region supposedly contains many comets, which are occasionally pulled out of the Oort Cloud and sent toward the Sun. However, due to the distance there is no observational evidence that the Oort Cloud exists, and it cannot be the source of short period comets.
It has long been known that comets can survive only a limited number of passes near the Sun because they lose some of their material every orbit. Short-period comets would eventually become invisible because they would eventually stop producing a coma—they would have no more material to lose.11
Estimates of the visible ‘lifetime’ of short-period comets are uncertain but are generally of the order of thousands of years. They could not last millions or billions of years. Thus, scientists who believe the solar system is billions of years old have proposed various means of supplying new short-period comets as the old ones ‘burn out’.
One popular view is that short-period comets come from the region beyond Neptune, known as the Kuiper Belt. A few hundred objects have been observed beyond the planet Neptune in roughly circular orbits. Though it is possible for Neptune or other planets to move these Kuiper Belt objects into short-period-comet orbits, this does not seem to occur frequently enough to resupply the short-period comets.12
Also, the Kuiper Belt objects we know of are actually much larger than comets.
Other models proposed to explain the presence of short-period comets in a billion-year solar system have difficulties also. For instance, scientists have looked into the possibility that short-period comets come from long-period comets.13 But there are a number of problems with this, including the low inclinations of the short-period comet orbits. Also, there should be more dust detected if so many comets ‘converted’ from long to short-period orbits.
It is simpler and more plausible that the solar system is young and that short-period comets are not being ‘resupplied’ at all. This avoids many difficulties with explaining where all the comets come from and what happened to them. Thus we can accept that the Earth and solar system are only several thousand years old.
Our solar system is young
These are a few examples of scientific evidence that pose problems for those who claim the solar system is billions of years old. This evidence suggests our solar system is young, and other evidences could be mentioned. There are always alternatives to the long-age naturalistic theories that are accepted by most of the scientific community. Biblically, the Earth and the universe are roughly 6,000 years old. As the exploration of our solar system continues, more and more evidence is discovered that points to a young solar system, consistent with the time scale recorded in the Bible. Our solar system is young.
