New view of gravity explains cosmic microwave background radiation

by D Russell Humphreys

Here I offer a new picture of how gravity works, depicting space as a membrane being greatly accelerated in a fourth spatial dimension. The Unruh effect, which connects acceleration with a blackbody temperature, could then explain the cosmic microwave background radiation. Later papers will apply this accelerating membrane model to galaxy redshifts and the Pioneer anomaly.

In my 1994 book, Starlight and Time,1 I interpreted scriptures mentioning a stretching-out of the heavens as supporting a large expansion of the universe. But in 2011 John Hartnett pointed out a scriptural reason why that interpretation is probably incorrect.2 He suggested that the red shifts of light from distant galaxies may have a different cause than expansion. My 2008 cosmology3 allows for a different cause: a slow increase of gravitational potential. What would cause the increase? I plan to show in a later paper how, according to the new view of gravity I present here, it would be caused by the stretching of the fabric of space, without much expansion.

In 1905, when Albert Einstein introduced his special theory of relativity, he sought to dispense with the æther.

Section 1 below gives scriptures explaining what the fabric of space is, and several of its important features. My 1994 book discussed those ideas. It pointed out how they help to resolve the paradoxes of relativity and quantum mechanics, allowing us to visualize them in a simple way.4 Section 2 gives scriptural reasons to think the stretching was a sudden increase of tension in the fabric of space. Section 3 gives scriptures implying that the fabric of space is thin in a fourth, unperceived, spatial dimension.

Section 4 shows how these qualities of space contribute to a new picture of how gravity works, explaining what seems to underlie Einstein’s gravitational field equations. I depict the fabric of space as being greatly accelerated in the fourth direction. Section 5 shows how the acceleration explains the cosmic microwave background. Section 6 suggests that the acceleration may be centripetal, as on the rim of a rotating wheel.

In the next three sections, I take literally a number of scriptures which many people have regarded as figures of speech devoid of physical meaning. But as we go though those scriptures, note that most of the figures of speech occurring in them are similes. In the Bible as well as in everyday language, a simile usually explains a poorly known but real thing by comparing it to a well-known thing.5 For example, in ‘stretching out the heavens like a tent curtain’, the real but poorly known action is the main clause: ‘stretching out the heavens’. The well-known idea is in the adverbial phrase: ‘like a tent curtain’. So the similes below are evidence for the reality of the things they describe.

1. The heavens are a real material

The Israelis of Bible times, to whom, and by whom, God wrote the Old Testament, had no way to distinguish between the earth’s atmosphere and what we now know is the vacuum of space above it. That distinction did not become clear until after Torricelli invented the barometer in AD 1643. It would be quite reasonable that God, wanting to be understood accurately, would speak to the Hebrews using the word for ‘heavens’ just as they used it: as meaning all of the expanse above the earth’s surface, both atmosphere and vacuum. He apparently used the word that way when He said that what birds fly in, namely the atmosphere, is merely “the face of the expanse of the heavens”, Genesis 1:20 (literal reading of the Hebrew text).

fig-1
Figure 1. If space is truly a fabric, it must be woven exceedingly fine, with the threads very much closer together than the size of a proton, ≈ 10-15 m.

Furthermore, Scripture often makes a distinction between ‘the heavens’ and ‘the host of the heavens’ (Genesis 2:1, Nehemiah 9:6). The latter are the bodies in the heavens; the former is the space containing those bodies. Genesis 1:1 says that God made the heavens, a seemingly empty space, before He made the sun, moon, and stars four days later (Genesis 1:14–19). So the heavens are space itself.

Generally we think of space as a true vacuum, an empty volume which contains some material here and there, such as air or stars. But Scripture speaks of space as a real material. The heavens can be torn (Isaiah 64:1), worn out like a garment (Psalm 102:26), shaken (Hebrews 12:26, Haggai 2:6, Isaiah 13:13), burnt up (2 Peter 3:12), and split apart (Revelation 6:14). These verses make sense if space is indeed a real material. Many of these verses compare the material to a fabric, hence the phrase ‘the fabric of space’ (figure 1).

Nineteenth-century physicists, such as the creationist James Clerk Maxwell,6 regarded space as pervaded with, or equal to, an intangible material called the æther (or ‘ether’, but not the anesthetic gas). Maxwell had noticed that electromagnetic experiments would make sense if the vacuum could be electrically polarized (indicating bound electric charges hidden in it) when one applied an electric field to it.7 This involved the idea of ‘displacement’ electric current in a vacuum,8 which in turn led him to the discovery that light is an electromagnetic wave propagating through the æther. The properties of this ‘luminiferous medium’, as he called it, determine the speed of light, just as the properties of water in a pond determine the speed of waves moving over it.9

But most theorists avoid thinking of the extra dimension as anything more than a mathematical convenience.

In 1905, when Albert Einstein introduced his special theory of relativity, he sought to dispense with the æther.10 However, in 1920, in a little-known address,11 he came back to the concept of an æther: “According to the general theory of relativity, space without ether is unthinkable.” He had found that his 1916 theory, general relativity, insists on space having physical properties, in particular being bendable in the same way that a solid material is bendable. He hastened to explain that we cannot measure our speed with respect to the æther, but he did not back down from saying it is real.

Academics ignored the 1920 address, and while not recanting it, Einstein did not publicize it or repeat its ideas. Hence the idea of an æther remained in the state of disrepute into which Einstein had put it in 1905. However, modern physicists began to find it was essential. Quantum field theory is built on the assumption that all space is filled with ‘fields’ which have mass and oscillate like particles.12 This ‘quantum vacuum’, a modern code name for the æther, makes forces between metal plates in a vacuum (Casimir effect), affects the orbits of electrons in atoms (Lamb shift, vacuum polarization), explains the appearance of electron-positron pairs from a vacuum (Dirac electron ‘sea’),13 and determines the speed of light.14 Other modern code names for the æther are ‘spacetime’, ‘continuum’, ‘manifold’, ‘substratum’, and ‘plenum’, often in various combinations. Though most modern physicists are reluctant to admit it even to themselves, the bottom line is that they believe that space is a real material, an æther.15

This modern æther is pervasive. It moves through us as we move through it. The quantum physics of solids offers an explanation of how this could be, based on the Pauli Exclusion Principle. This principle could allow us to move through a material space as freely as an unbound electron moves through a perfect crystal.16 This medium, space, also offers a reason why there should be a relativistic speed limit, namely the speed of light, on particles moving through it. If space were a truly empty nothingness, why should there be a speed limit at all? Instead, motion through this medium affects our measurements in such a way that, regardless of our speed through the medium, we always get the same number for the speed of light.17 The existence of a real æther thus eliminates a number of paradoxes that boggle the minds, not only of students, but also experienced practitioners of physics.

2. God has stretched the material

Starlight and Time pointed out seventeen verses18 in Scripture which describe a stretching or spreading of the heavens. Here are two of them:

“Who stretches out the heavens like a tent curtain, And spreads them out like a tent to dwell in” (Isaiah 40:22; NAS),
“Stretching out the heavens like a tent curtain” (Psalm 104:2; literal Hebrew).
If the heavens are a flat sheet of fabric existing in a large empty ‘hyperspace’, then there exists the possibility that the sheet may be moving within the hyperspace.

Lately I’ve noticed that ‘spreading’ and ‘stretching’ may be two separate but related types of action, as they are in pitching a tent. But in 1994, I made no such distinction. Because of the phrase ‘stretches out’, I was taking these verses as supporting the idea of a very great expansion of space. In cosmologies of that sort, the redshift of light from distant galaxies turns out to be proportional to the factor by which space expands during a photon’s travel from a distant star to Earth.19 To explain the redshifts of light from the most distant galaxies we can observe would require that space has expanded by a factor of at least ten. Space would have to be exceedingly stretchable, more so than even some very elastic materials we have today, such as rubber. My second cosmology, in 2008, allowed for such a very great expansion, although it did not insist upon it.

But as I mentioned earlier, early in 2011 John Hartnett pointed out to me that Old Testament readers knew of no highly elastic fabrics. Speaking to such readers, as well as to us today, why would God compare the material being stretched to such materials as tent curtains, which can extend their dimensions by only a few percent before tearing? It is more likely, he said, that the expansion of space has been negligible, and that the cause of galaxy redshifts is something else. Late in 2011, he published that idea.2

I soon realized that he was right. Then I began to consider what the ‘stretching’ verses might actually mean, and how that might affect cosmology. When we want to stretch an ordinary (non-elastic) fabric, we put it between our hands and pull it from each side. That makes a tension in the fabric, a force at every point within it that tends to pull it apart. The fabric responds by extending its length a small amount. If we increase the pull, increasing the tension, it will extend a bit more. But we cannot extend the fabric’s length more than a few percent without tearing the fabric.

fig-2
Figure 2. The Tabernacle of Israel in the wilderness had its covering stretched taut by applying tension. This full-scale model is in Timna Park, Israel, about 15 miles north of Eilat.

This understanding of the Hebrew verb natah, translated ‘stretches out’ in the above verses, appears to fit within its range of meaning in lexicons20 and its usage in such verses as Isaiah 54:2,

“Enlarge the place of your tent; Stretch out the curtains of your dwellings, spare not; Lengthen your cords, And strengthen your pegs.”

It is likely that the outer coverings of the tabernacle in the wilderness were stretched taut, as figure 2 shows, to prevent them from flapping in the wind. This is an example from Old Testament times of applying tension to a fabric without having much extension of its length or width.

Let us consider when the stretching occurred, or whether it is still occurring. Of the seventeen verses I list in reference 18, nine are like Isaiah 40:22 and Psalm 104:2 above. They appear in English as if the verbs are in the present tense, but in the Hebrew text they are simple participles, which in that language carry no tense information in themselves.21 Two other verses, Job 37:18 and Psalm 144:5, do not speak of the original stretching or spreading by God. But the other six verses use the past tense. Two of them (2 Samuel 22:9–10 and Psalm 18:8–9) follow a qal perfect verb with a waw consecutive prefixing a qal imperfect verb, which implies past action. The remaining four (Isaiah 45:12, 48:13; Jeremiah 10:12, 51:15) are qal perfect, implying a past action. Many of the seventeen verses connect the stretching with events of the Creation Week. So we can conclude that the stretching (an increasing of tension) occurred during the first six days of creation, and was completed (stopping the increase of tension) during that period. In order to have Newton’s G of eq. (7), in section 4, be constant by the third day of creation, when Earth started functioning as a planet (and certainly before the orbiting heavenly bodies were made on the fourth day), it would be simplest to have the tension τ stop increasing by the end of the second day of creation. The results of the increase, such as a slow increasing of the gravitational potential of the cosmos, could still be continuing to this day.

3. The heavens have a fourth dimension

Think about the shape of this fabric, the space we live in. It appears to have only three dimensions (directions): length, width, and height. Lay a sheet of paper flat on a table. It is 8.5 inches (22 cm) wide by 11 inches (28 cm) long, but it is only 0.003 inches (0.008 cm) thick. It doesn’t occupy much of the height direction at all. Now roll up the paper like a scroll. You used the third dimension, height, in the air above the table, to roll it up, and the thinness of the paper in that dimension allowed you to do so. So if an object is thin in one of its dimensions, you can roll it up. But here is an amazing thing … Scripture says the same thing about the heavens:

“And the heavens shall be rolled up like a scroll” (Isaiah 34:4; NKJ),
“And like a mantle You will roll them [the heavens] up” (Hebrews 1:12; NAS).
fig-3
Figure 3. Rolling up the heavens like a scroll.

Here again God depicts the heavens as a real material that He can manipulate. In the three directions we can see, the heavens are very thick. Yet God says He will roll them up like a scroll (figure 3). That implies that the heavens are thin in a fourth direction that we can’t see. The biblical analogies with a curtain of fabric support that idea. Moreover, there must be more room in that fourth direction, which allows the rolling-up to occur. The future tense of these verses implies the heavens are not in a rolled-up condition at present. In the fourth dimension we can’t perceive, space is nearly flat, like an unrolled scroll or cloak. The three dimensions we can see would exist as a thin sheet within a larger four-dimensional space, for which I would like to borrow the theoretical term ‘hyperspace’.22 As I pointed out in Starlight and Time,23 the extra dimension makes sense of the equations of Einstein’s General Theory of Relativity by giving room and a direction in which the ‘spacetime continuum’ can be bent. Einstein’s first cosmology, in 1917, made explicit use of four spatial dimensions.24 Later cosmologies, such as the big bang theories, use four spatial dimensions implicitly. But most theorists avoid thinking of the extra dimension as anything more than a mathematical convenience.25

This simple picture of an accelerating membrane, which I hesitate to call a ‘theory’, explains several puzzles about gravity and one about quantum field theory.

The interpretive principle in the last paragraph of my introduction takes the verses above as meaning the heavens will be rolled up physically—not figuratively. For if either ‘the heavens’ or ‘rolled up’ were figurative, the similes would be almost meaningless. They would be saying, ‘something figurative will have something else figurative done to it like a scroll or a mantle’. But what the figures would be depicting would be a total mystery. It makes much more sense to think that the words mean what they say, that the physical heavens will be rolled up physically like we roll up a scroll or mantle.26 Such a rolling-up apparently requires an extra dimension, an extra direction.

This fourth direction is not time. Relativity theory treats time as a real dimension, in our case, a fifth dimension. That is, the fabric is really spacetime. Its time dimension, or direction, differs from the space directions in several ways. First, we only observe a narrow slice of time, the present. Second, the slice seems to be moving through time, from the past into the future. Third, physical phenomena can only develop in one direction of time, toward the future. For example, if we toss a stone into a pond, we only see waves coming from the impact, forward in time, even though all the equations we know would allow waves to travel backward in time also. If that were the case, we would first see waves in the pond converging on the future point of impact, then the stone hitting the water, and finally waves radiating outward from the impact. In real life, something seems to compel the waves to travel only futureward. But in spite of the special nature of time, the equations of relativity seem to say that the past and the future physically exist, and that the timeward direction is just as real physically as the space directions. This, of course, is an interpretation of time that is open to question, discussion, and further research. I will apply this interpretation in section 6.

The fabric of space is exceedingly transparent, because we can see through it for billions of light-years, over a wide range of wavelengths.

Why can’t we see the fourth spatial direction? We are creatures confined within a fabric which is very thin in the fourth direction (so we also are very thin in the fourth direction). It appears that we usually see light coming at us only from within the fabric, not from outside it.27

But why can’t we imagine it, visualizing it as a direction perpendicular to the three directions we can see? I don’t know. Speaking for myself, my imagination is limited to the kinds of things I can see in three dimensions. I have a similar problem with time as a dimension. I can’t see either my past or my future, or point to a direction for them. But I do perceive myself moving through time, out of the past and toward the future. Perhaps we can imagine the fourth space direction similarly.

In practice, the way to imagine the fourth dimension is by an analogy: eliminate one of the three space directions you can see, and replace it with the fourth direction. For example, call the east-west direction x, the north-south direction y, and the up-down direction z. Now, imagine everything as being compressed in the z-direction down to a flat sheet, the x-y plane. Now tack a vertical axis onto the x-y plane and call it w.

That’s the extra direction, the fourth dimension. The plane is very thin in the w-direction. You and I are embedded in that plane, so we also are very thin in the w-direction. The total number of space coordinates describing the real world would be four (w, x, y, z), but to visualize things we only show three (w, x, y), making the world into a ‘flatland’ as a model. If you noticed, that is what I depicted in figure 3. Edwin A. Abbot’s entertaining nineteenth-century novel, Flatland, shows the usefulness of this method for imagining the fourth dimension.28

4. Adding acceleration gets gravity

If the heavens are a flat sheet of fabric existing in a large empty ‘hyperspace’, then there exists the possibility that the sheet may be moving within the hyperspace. Imagine a force pushing the sheet ‘upward’ in the w-direction. If the force is spread uniformly throughout the sheet, then the whole sheet will remain flat and accelerate perpendicular to the sheet, ‘upward’ in the w-direction, at a rate determined by the ratio of force to the inertial mass of the sheet.

Inertial mass is an object’s property of resisting acceleration. That makes room for a possible distinction with the object’s gravitational mass, its property of attracting other objects or being attracted by them.29 I will discuss this possible distinction later.

fig-4
Figure 4. A trampoline far out in space needs to be accelerated in order for an object to make a dent in it.

Now imagine yourself riding along with the sheet in its accelerating frame of reference. Assuming the sheet is like most fabrics, somewhat stretchable, let us call it a membrane. Put an object on the membrane. It has its own inertial mass (in addition to the mass of the sheet), and the additional mass resists being accelerated. As the membrane accelerates upward, the object sinks into the sheet. At and beyond the perimeter of the object, the membrane tilts down, and the tension in the membrane around the object now has a small component in the upward direction. That applies an additional upward force to the object which slows its sinking into the membrane. Eventually (rather rapidly for all but very large objects) the depth of the object reaches a point where the tensional force makes the object accelerate upward at the same rate as the membrane.

You can visualize all this by imagining a trampoline with a massive object, say a large iron ring, on it … but put them far out in space where there is little or no gravity; then the ring will make no dent in the trampoline, because it has no weight in zero gravity. But if you now accelerate the trampoline perpendicular to its plane, the ring will now make a dent, as in figure 4. There will be a sloped region around the ring. A smaller object in the sloped region will slide toward the ring. It will slide faster as it approaches the ring, because the slope gets steeper. This suggests that we can get an explanation for gravity from this simple picture of an accelerating membrane.

That turns out to be true. One can derive Einstein’s General Relativity equations for gravity from it. But here I will be more approximate and show how it results in Newton’s gravity. Many textbooks show how a distribution of force f will deform a stretched string or membrane having a tensionτ. For a membrane the deformation w, the deviation from flatness, fits the two-dimensional Poisson equation:30

equ-1

To derive that, the author (Richard Feynman) took the force f to be in the positive direction, upward. In our case, we want the force to be downward, and produced by the inertia of a mass distribution p accelerated upward by the membrane with the acceleration g:

equ-2

Let us call g the cosmic acceleration.31 As we will see later, it is a very large number, not the 9.8 m/s2 acceleration of gravity at Earth’s surface often denoted by the same symbol. Putting (2) into (1) and generalizing to a membrane with three dimensions (x, y, z) being deformed in a fourth dimension w, we get

equ-3

As textbooks show, the potential Φ (energy per unit mass) associated with the deformation w in this situation is

equ-4

Multiplying eq. (3) by g and substituting eq. (4) gives us an equation for potential,

equ-5

Compare this with Poisson’s equation as applied to gravitational potential,32

equ-6

where G is the Newtonian gravitational constant, 6.673 x 10-11 m3/kg-s. Eqs. (5) and (6) become the same when we let

equ-7

Poisson’s equation (6) leads directly to Newton’s law of gravity, which we can now visualize. The slope of the depression around a large mass causes a small mass on the slope to slide toward the large mass. Its acceleration will be the component of the cosmic acceleration g which is lined up with the slope; only a very small fraction of g. Being very thin in the fourth direction, we don’t feel g at all when space is flat. But two masses will feel an attractive force toward each other which increases as they get closer together.

This simple picture of an accelerating membrane, which I hesitate to call a ‘theory’, explains several puzzles about gravity and one about quantum field theory:

  1. It explains Einstein’s equivalence principle, the initial assumption on which he based general relativity.33 The principle says that in a small locality one can replace a gravitational field with an equivalent accelerating reference frame. The principle requires that gravitational mass, the mass that produces and responds to gravitational field, be equal to inertial mass. Newton, on the basis of Galileo’s experiments, also assumed equivalence of the two sorts of mass. Experiments have so far shown it to be true for all sorts of matter and even for energy.34 But it has never been clear why it should be so. In the accelerating membrane model, inertial mass produces and responds to gravity, so it is equal to gravitational mass.
  2. It explains why mass should deform the fabric of spacetime.
  3. It explains why deformed spacetime should affect particles with mass, producing gravitational force, and compelling objects to follow geodesic (shortest or longest possible) paths in spacetime. The latter is usually assumed in general relativity, and derivations of it from first principles have never found wide acceptance.
  4. It provides the action (energy-time) principle from which one can derive the Einstein gravitational field equations.35 The derivation of Newtonian gravity, above, stems from the same kind of considerations.
  5. It resolves the cosmological constant problem, the contradiction between (1) the requirement by quantum field theory that the vacuum have a very high mass density, and (2) the requirement from gravity observations that the vacuum have a mass density (proportional to the famous cosmological constant) that is either very small or without significant gravitational effect. The discrepancy is huge, nearly 120 orders of magnitude!36 I am proposing that the force accelerating the membrane of spacetime is the same everywhere. This makes the membrane flat wherever there is no additional mass from objects, so the mass of the membrane does not contribute to gravity. Only additional mass from objects produces deformations which cause gravity. Thus the accelerating membrane idea allows the mass density of the vacuum to be quite large, resolving the problem.

Last, textbooks show37 that allowing time variations in the membrane expands eq. (6) into a wave equation:

equ-8

where c is the speed of the waves, given by the ratio of tension to the mass density ρm of the membrane38

equ-9

As I mentioned in point (5) above, the invisible mass density of the vacuum, i.e. the membrane, is very large; much larger than any visible mass density:

equ-10

Eq. (8) will fit relativity (be Lorentz-invariant) if the speed c of waves in the membrane is also the speed of light. Then eq. (8) will be the moderate-gravity approximation of the most important component of Einstein’s gravitational field equations.39

5. Acceleration gives the cosmic microwave background

Is there any evidence that the fabric of space is accelerating in the fourth direction? I think so. In 1976, William Unruh40 showed that an accelerating particle would experience blackbody radiation with a temperature T given by41

equ-11
fig-5
Figure 5. Spectrum of cosmic microwave background observed by WMAP satellite. The curve is the theoretical black-body spectrum for the listed temperature. Data points and error bars all fall within the thickness of the curved line in both absolute intensity and wavelength. (Graphic after WMAP/NASA).

Here ħ is the reduced Planck constant (h/2π), 1.0545 x 10-34 J s, g is the acceleration in m/s2, c is the speed of light, 2.9979 x 108 m/s, and k is the Boltzmann constant, 1.3807 x 10-23 J/K. In this case, bound and unbound particles in the fabric of our space would be accelerating through the quantum vacuum of hyperspace, and the particles would experience blackbody radiation having temperature T.42 They would oscillate and emit, within the fabric of our space, blackbody microwaves of the same temperature, which we could then detect. A few theorists disagree that the particles would radiate,43 but a very detailed review article cites many authors who disagree with that.44

The fabric of space is exceedingly transparent, because we can see through it for billions of light-years, over a wide range of wavelengths. So the invisible bound particles of the medium must have very low cross-sections for absorption and scattering, which would be expected if the binding forces are very high. However, in a real medium the emission cross-section would not be zero, so we would receive radiation from bound sources in the vacuum, from a wide range of distances. If the cosmic acceleration is large enough, we should be able to detect such radiation, and it should have the spectrum of a black body. It happens that we observe such radiation, namely the famous cosmic microwave background (CMB). It fits a blackbody spectrum very precisely (figure 5), giving a temperature of 2.72548 (± 0.00057) Kelvin.45 This would be the temperature of the fabric of space, which would be heated by the Unruh effect. The small Doppler-like shift we observe in the CMB46 thus appears to be caused by our velocity with respect to the fabric of space.

If indeed the CMB is caused by cosmic acceleration, then we can calculate the amount of acceleration by solving eq. (11) for g:

equ-12

Using the CMB temperature for T gives us the cosmic acceleration:

equ-13

This, of course, is an exceedingly great acceleration. It needs to be great in order for general relativity derived from this picture to be accurate for the largest gravity we might observe. For example, the gravitational acceleration near the event horizon of a black hole with the mass of the sun would be 1.5 x 1013 m/s2 (times a relativistic factor greater than one).47 In such regions the high value of g would make general relativity accurate to better than one part in ten million. Also, g represents a maximum possible gravitational acceleration, which might help resolve some of the paradoxes associated with black holes.

Last, let us calculate the mass density ρm of the membrane from the value of g above. Putting eqs. (7) and (9) together gives:

equ-14

This gives the mass density of the membrane:

equ-15

From eq. (9), the tension, which is the same as the energy density, of the membrane is

equ-16

The above values are well within some (very broad) limits given by theorists for the mass and energy density of the quantum vacuum.48 Converting the units of eq. (16) to units more familiar to me, the tension is 5.386 x 1045 Bars (1 Bar is about 14.7 pounds per square inch). The membrane, the fabric of space, must be exceedingly strong in order not to tear under such an enormous tension. That could be why Psalm 150:1 (NAS) says the expanse of the heavens (Genesis 1:8 NAS) is ‘mighty’.49

fig-6
Figure 6. Fabric of spacetime as a rotating wheel in hyperspace.

6. The acceleration may be centripetal

If the cosmic acceleration were linear, in a straight line perpendicular to the plane of the membrane, we would have travelled a very large distance in 6,000 years of our time. Hyperspace would have to be very large to accommodate the motion. That may be possible, but I suspect that the acceleration may be centripetal, such as one would experience on a rotating wheel. That would mean that we, and the fabric of space, have a very high velocity v in hyperspace, in a direction perpendicular to the cosmic acceleration. This velocity could be in the fifth direction, timeward, in the direction of our future (figure 6). See my remarks on time in section 3. Spacetime would have a principal radius of curvature R in the timeward direction. The accelerating force would then be the tension τ that holds the fabric rim of the wheel together. That would make the accelerating force uniform throughout space. The cosmic acceleration g in the rotating frame of reference would be simply

This picture leads straightforwardly to Einstein’s gravitational field equations. There are some interesting scriptures that hint at a rotation through time, but I don’t have the space in this article to discuss the idea further. It is sufficient for now that a cosmic acceleration exist, whether linear or centripetal.

7. Conclusion

It is difficult for most people to imagine space as a physical material with a tension and a fourth spatial dimension. It may help to remember that those ideas come directly from taking Scripture straightforwardly. Adding a cosmic acceleration yields a simple picture that underlies the equations of gravity and solves five long-standing mysteries about it. One of them is the well-known conflict of the cosmological constant with quantum field theory. Last, the acceleration leads directly to an explanation for the cosmic blackbody radiation, which should help creation cosmology. In one or two future papers I plan to apply this new view of gravity to (1) galaxy redshifts,3 and (2) the Pioneer anomaly50 and recent developments about it. I hope this new view of the heavens will help us better see the glory of God in them.

  27. One reason for the confinement of light to within the fabric of our space could be that the speed of light in hyperspace is very much greater than in the fabric of our space. Thus, almost all light emitted from within our space would suffer total internal reflection, as in an optical fibre. Or, the two boundaries of the fabric in the w direction could reflect photons for some other reason. The same kind of constraint might be what prevents matter in the membrane from leaving it. In either case, light would effectively propagate only in the x, y, and z directions, not in the w direction. The blocking of light would also apply to light coming from hyperspace toward us. It may be that occasionally God enables light and matter from hyperspace to enter the fabric of our space, which could explain the instances of the heavens being ‘opened’ in Scripture.

Joe B., United States, 29 September 2016

Thank you CMI for another refreshing article that tries to make sense of what we observe as opposed to what we postulate but cannot prove (or test). I realize that the deeper aspects of physics are more difficult to deal with because we can see only the effects but not the forces.

For me the most important note in the article is the declaration that space is a thing and the vacuum is not void as we are taught, something I never believed. For only in the context of an aether or whatever we want to call the medium, does the idea of the intrinsic impedance of free space, along with permittivity and permeability of the vacuum make any sense or have context, particularly considering their relation to the refractive indices of other materials.

Dr. Humphreys, in this light, have you given any thought to the similarities between fluid dynamics, electrodynamics, and magneto-hydrodynamics with any relationship to gravitation? We know that they all have the standard wave equation in common (and much more), but to me the really interesting part is that in EM:

c = sqrt[1/(permeability * permittivity)]

and the velocity of sound waves in a fluid has been described as:

v = sqrt[1/(compressibility * fluid density)].

I will leave it there to let our imagination wander and there is not enough space to flesh any of this out here… I would love to hear your thoughts.

-Joe

Russ Humphreys responds

Thanks for your thoughtful question, Joe. Yes, I’ve given it a little consideration, but I remain a mass of confusion about it. Your second equation, which some readers may be familiar with, is a close parallel to eq. (9) of my article, with tension relating to compressibility and mass density being the same in both equations. I’m sure that’s no surprise to you. It’s harder for me to understand why your first equation, the one Maxwell found giving the speed of electromagnetic waves, should be involved. Why should the speeds of light waves and and mechanical waves in the fabric of space be the same? As I commented, they have to be equal in order to have my eq. (8) be what physicists call “Lorentz-invariant”, i.e., to fit in with relativity. But that touches on something I’ve never understood anyhow: in relativity, why should the speed of electromagnetic waves affect how things that are seemingly non-electromagnetic behave? In your first equation, why should permeability (the magnetizability of the fabric of space) and permittivity (the electric polarizability of the fabric of space) be related to mechanical properties of the fabric of space, namely the tension and mass density? There is some deep connection here, but so far it has escaped me.

Having to write “fabric of space” three times above makes me wish I had a less awkward name for it. “Aether” or “ether” doesn’t satisfy me, because those terms call up the impression of a very tenuous gas that doesn’t penetrate into solids. “Quantum vacuum” sounds even more tenuous and, worse, invokes the mysteries of quantum theory. The other code terms, like “space-time continuum” have enough syllables to make them awkward to use. Here’s a new term for the fabric of space I just thought of a few days ago: pleroma. It’s from a Greek word (πλήρωμα) meaning “that which fills.” In the New Testament it is often translated “fullness.” Some ancient Greek writers used it, a bit mystically, to mean “that which fills the cosmos and permeates everything in it.” I like that meaning, though I’m applying it non-mystically here. Besides, it sounds cool! I’m wondering how readers would like it in future articles I may write.

Glen J., United States, 24 September 2016

I don't pretend to understand all the math and theory in the article but I was stunned by it. Amazing insight!

I wonder if the force is centripetal would there be some type of torque component to it?

Russ Humphreys responds

Not necessarily. The inertia of such a wheel could just keep it spinning freely in a total vacuum without slowing down. However, if there is some slight amount of friction on the wheel’s turning, there would be a torque, and the wheel would slow down by a tiny percentage per unit time. But even a tiny percentage decrease of the very high speed of the wheel would strongly impel particles along the rim of the wheel, in the direction of time elapsing on the rim. That could explain why time goes in only one direction, something physicists and philosophers have puzzled about for years. It’s fun to speculate about, but there are so many things we don’t understand about time that I wouldn’t hang my hat on it.

Stephen L., United States, 24 September 2016

Thanks for this fantastic article! I think it is such a shame that so many people just blindly accept the secularist lie that redshifts and CMB can only be explained in a big bang created universe. You explained both of these phenomena from a biblical view of science, without any adherence to the bogus, pseudoscientific big bang myth.

Praise the Lord for scientists like you!

Kenneth I., United States, 24 September 2016

This is a bit mind-bending. It also brings to mind the vision of Ezekiel chapter 1. It makes me wonder if Ezekiel was trying to describe the Creation as viewed from outside of our time-space continuum. Does this image of a wheel in the middle of a wheel, the color of beryl, the four likenesses, and the spirit in the wheel resonate with anybody but me?

Russ Humphreys responds

Well, I find it mind-bending too, even though I’ve had this on my mind since September 1969, just a few months after I accepted Christ as my saviour. On Ezekiel’s wheels, if you take a look at the comment above by David S., you’ll see he had a similar thought. I also was hoping to find Biblical support for my “wheel of time” there, but Zeke’s wheels seem to be much too small, not universe-sized. So they wouldn’t be much more illustrative than the Biblical mentions of chariot wheels. However, I did find several Scripture passages that were more direct. One of them is in the Greek of James 3:6, which says “And the tongue is a fire … which sets on fire the course of life … ” The Greek for the last four words says, very literally, “the wheel of the Genesis.” The passage is an extended metaphor comparing, among other things, the tongue, fire, and this “wheel.” Most metaphors compare visualizable things with other visualizable things, but for two millennia Greek scholars have been puzzled about what a visualizable “wheel of Genesis” might be. They had to reach into extra-Biblical literature to come up with phrases like “the course of life.” But that is not very satisfactory because it is an abstract phrase, not something more concrete. I’m proposing that the “wheel of Genesis” refers to my physical wheel of time. However, if this proposal doesn’t help you, just forget about it.

Pastor Doug J., United States, 24 September 2016

This article both thrilled, inspired, enthused, perplexed, and amazed me. I read a portion of it aloud to our Christian school students today (as much as time allowed) and then finished reading it aloud to my wife tonight. I also recently showed your recent "Light-Years? No Problem!" DVD to our church's Adult Class, College & Career Class, and Christian school students. Thank you for all you do. Wonderful stuff!

Thaddeus L., United States, 24 September 2016

I am no physicist, and don't really understand the equations, but I do understand the pictures the equations present and as I read this I couldn't help but think this is really ground breaking! Especially if it solves all those puzzles about gravity and quantum field theory. I just had the impression: "This is true."

Maybe I am over estimating the importance of this research, but I couldn't stop thinking that this needs to somehow get published in mainstream scientific journals. Obviously, the references to Scripture would make that challenging, but those can be removed and the impact wouldn't be lost.

Very excited to read the future papers!

Robert P., Australia, 24 September 2016

Thank you Dr Humphrey,

For your adventurous and bold hypothesis.

Intuitively it is easier for me to imagine a fourth spatial dimension, than a fourth 'time' dimension.

I would be interested in how your model affects massive bodies moving along this 'fabric of space'.

In my mind for many years now, I have what I euphemistically called my “carpet bowls ‘theory’ of space-time”.

What I mean by this, is if you imagine a carpet laid with generously padded underlay and carpet bowls made of 50kg lead balls. Then if you briskly roll the ball across this carpet, it will produce a standing bow wave in the carpet, ahead of the rolling ball, that would tend to retard its motion. This is analogous to the increasing apparent mass of a body as its velocity approaches the speed of light.

If you think of a local 2D vector set at the contact point of the ball on the carpet, or possibly slightly ahead of this point, with the requirement that one axis is locally normal to the carpet and the other is tangential, then eventually the standing wave (standing or stationary relative to an observer moving with the ball) will be vertical. That is the local tangential vector will be normal w.r.t. undisturbed free space. That is time stops when the object become infinitely massive at the speed of light. Or the projection of the time vector onto the undisturbed free space drops to zero.

Your allowance of an additional 4th spatial dimension interwoven with the time dimension makes this more plausible.

By the way I think there is a typographical error in the statement of the Harmonic function in equation (3). I think you meant the third term to be a second partial derivative wrt z, not y again.

I look forward to your future articles, don’t stop stretching forward!

God Bless

Robert P.

Russ Humphreys responds

Very thoughtful and good comments, Robert. You may well be on to something in having your “carpet wave” be the specific mechanism for mass increase with velocity. I’m also glad you noticed the typo in eq. (3), because it shows you understand the math well (which makes me feel good about your commendations, thanks). [CMI editors: this error (and a few others) has since been fixed.]

Colin N., United Kingdom, 23 September 2016

Sorry this is a question rather than a comment, but it doesn't "require" an answer as I'll survive if you choose not to respond. Just wondering whether the Carmeli/Hartnett version of relativity, assuming spacevelocity as a fifth dimension, still holds under Humphreys' alternate fifth dimension? My maths isn't good enough but I can't see why the nature of the fifth dimension should matter to the maths. Particularly as Humphreys' extra dimension is presumably orthogonal to the others, whereas I would imagine spacevelocity isn't. Sorry if I'm jumping the gun on research in progress.

Russ Humphreys responds

Well, first, I think John Hartnett is no longer enthused about the Carmeli/Hartnett cosmology. That’s because John and I, because of Scripture he first pointed out, no longer are convinced that very much expansion (Carmeli’s idea must have a large expansion) has actually taken place. Red shifts can have a different explanation. Second, the mathematics in Carmeli’s cosmology do not seem to allow his 5th dimension (speed in our 3 dimensional space) to be converted into a space dimension. I’m convinced of that because I tried hard to make such a conversion. Sorry to be a wet blanket about that.

Jeannette P., United Kingdom, 23 September 2016

Thank you very much for a fascinating article. The maths was way beyond me, but it was amazing, as well as mind-boggling, all the same.

I was especially intrigued by # 6 because of having wondered previously if Ezekiel's vision of the cherubim and their wheels "Full of eyes" could possibly relate to the structure of the cosmos itself (Galaxies look rather like eyes).

Mitch C., United States, 23 September 2016

Thank you, Dr. Humphreys, for such a clear and concise presentation of your analysis, and for tying together the relevant scientific evidences with the corresponding biblical data into a model that so neatly explains various mysteries that have eluded previous secular and creationist models. This is an excellent example of creation science shining the light of scripture on the workings of God's creation. When the scriptural is testimony is rejected or obscured, men will be "always learning and never able to come to the knowledge of the truth" (2 Tim 3:7).

David S., United States, 23 September 2016

A comment that may have nothing to do with the fabric of space but Paul in Eph 3:18 describes the love of God in 4 dimensions, something I don't understand.

Second a bone head question: from red shift we know the speed of an object when the light left it. For distant objects do we somehow know distance when the light left or is this somehow inferred?

Then this article suggests Ezekiel's image of wheels in wheels. It's a good thing God knows how this works and upholds it.

Russ Humpreys responds

Yes, astronomers have a number of good methods for estimating the distance of even very far-away objects. It really is a big universe. The wheel of time I’m imagining would have to be similarly big. The wheels beside the cherubim that Ezekiel described seem to be much smaller, roughly people-sized.

M. K., United Kingdom, 23 September 2016

Extremely interesting! Now, I wonder, is this somehow compatible with Moshe Carmeli´s theory of cosmological relativity? Can it also explain the galaxy rotation curves without dark matter? How does it relate to the distant starlight issue? Does it allow for time dilation or ASC in that context? Thank you and God bless!

Shaun Doyle responds

This model is indeed different from the Hartnett-Carmeli model and the ASC model, so we would expect there to be differences. As to what this model could explain in the future, be on the look out for future articles!

Joseph M., United Kingdom, 23 September 2016

I am not mathematically minded, so I found the analogy or similes made the article easy to understand. I was wondering what type of similes would make "But Scripture speaks of space as a real material." easy to understand? The analogy of a trampoline doesn't fit. The closest I could get to a simile is the word 'experience', because I have always regarded something as material if we can hear, see, touch, smell, and taste that something. But regarding space as a real material thing fits outside the scope of these five sense. So does this mean there is a sixth sense that we can call 'experience' because we experience space by living in space in the present?

Shaun Doyle responds

The simile is implicit in the statement. If we get a piece of cloth and ‘experience it’ with our senses, then we have an experiential analogy for what space is.

But do we have a sixth sense to experience 4D physics? No. Rather, it means that we can’t rely on our experience of materiality to judge Dr Humphreys’ argument for space as a 4D material. Since our senses are ‘calibrated’ to 3D perception, we cannot feel what he is suggesting is real. But just because we can’t feel it doesn’t mean it isn’t real. Dr Humphreys calls it a material because (1) Scripture seems to and (2) the physics seems to work. As a side note, we actually have many more senses that just the ‘canonical 5’, such as our experience of hunger, thirst, and time.

Mark B., Australia, 22 September 2016

Wow! The fabric of my mind has certainly been stretched and I'm hoping it won't tear...

This is wonderfully exciting stuff and I am so appreciative of the work of Drs Humphries and Hartnett in trying to make sense of the immense and seemingly incomprehensible universe that God has created for us. How wonderful that it is "just" a physical entity and that it "just works" in ways that we may be just beginning to glimpse...

Also, how delicious that the simple metaphors and similes of Scripture might really be accurate *physical* descriptions of a universe that cosmologists themselves struggle to find language for! This is analogous to Genesis being a "simple" but accurate and TRUE historical narrative, not a complex (and wildly inaccurate) figurative description of History which in "reality" we are told is so vastly huge (in the time dimension).

Finally, it is so refreshing to see two scientists (who have several areas of [respectful] disagreement in their respective ideas of the universe) share ideas, give credit where some is due, agree that the other is right in some areas (and therefore adjust their own ideas), and generally co-operate such that the path to understanding God's Creation in it's most mind-spinning parameters can be made shorter. If only all scientists today could work this way (was it like this in the days of Newton, Kepler, Faraday, etc?) - we would find ourselves in a world where scientific knowledge would grow so much faster and I'm sure that such increased understanding could not fail to show who the Ultimate Designer is (that we already know through His revelation to us in Scripture)!

CMI is certainly blessed with so many extraordinary minds contributing to the work of the Ministry, and I, as a speaker, can't be too grateful for them!

Jim R., Australia, 22 September 2016

Hi CMI,

A fascinating article! The reconciliation of quantum and standard physics with an accelerating aether model is compelling.

I wonder if God might have patterned the universe on a sphere in the extra dimension(s) and we (part or whole of the universe) are on a section which experiences properties (centripetal acceleration) based on where it lies in the sphere. Is it possible that the spinning strip of fabric in Russell's illustration is like an equatorial strip on a spinning globe or do the properties of the universe point to it being absolutely uniform (i.e. a flat strip like in the illustration)?

Keep up the research!

Russ Humphreys responds

Thanks for the thought, Jim. I considered what I think you mean, but there’s a problem with it. With a spinning sphere, if you’re far from the equator (where the centripetal acceleration is greatest), then the fabric of the sphere will have a significant slope toward the equator. Because the centripetal acceleration is so great, everyone far from the equator would experience an enormous gravitational acceleration toward the equator. Sorry to be a wet blanket, especially because I would have liked a spherical form also.
