New time dilation helps creation cosmology
by Russ Humphreys
A new solution of Einstein’s gravitational field equations I published in
20071 clarifies a new type
of relativistic time dilation that I call achronicity, or ‘timelessness’.
Here I explain achronicity and show how it helps creation cosmology, offering new
ways to solve the starlight transit time problem.
Figure 1. The waters above the heavens, mentioned in Psalm 148:4.
In November of 1915 Albert Einstein published the crowning conclusion of his General
Theory of Relativity: a set of sixteen differential equations describing the gravitational
field.2 Solutions to these
equations are called metrics, because they show how distance-measuring
and time-measuring devices (such as rulers and clocks) behave. The equations are
so difficult to solve that new metrics, giving solutions under specific conditions,
now appear only once every decade or so. Metrics are foundational; they open up
new ways to understand space and time. For example, the first metric after Einstein’s
work, found by Karl Schwarzschild in 1916,3
not only explained the detailed orbits of planets, but also pointed to the possibility
that ‘black holes’ might exist.
Figure 2. A moving clock measures the spacetime interval ds
between two events.
In the fall of 2007 I published a new metric as part of an explanation of the ‘Pioneer
anomaly’, a decades-old mystery about the slowing-down of distant spacecraft.4 Compared to many modern metrics,5 the new one is rather
simple. It describes space and time inside an expanding spherical shell of mass.
I was interested in that problem because of the ‘waters that are above the
heavens’ that Psalm 148:4 mentions as still existing today above the highest
stars (see figure 1). The waters would be moving outward along with the expansion
of space mentioned in 17 Scripture passages.6
According to data in my previous paper, the total mass of the shell of waters is
greater than 8.8 × 1052 kg, more than 20 times the total mass of
all the stars in all the galaxies the Hubble Space Telescope can observe.7 However, because the area
of the shell is so great, more than 2 × 1053 m2, the
average areal density of the shell is less than 0.5 kg/m2. By now the
shell must have thinned out to a tenuous veil of ice particles, or perhaps broken
up into planet-sized spheres of water with thick outer shells of ice. It is only
the waters’ great total mass that has an effect on us, small but now measurable.
Figure 3. Gravitational potential F inside a spherical shell of
mass increases as radius R of the shell increases between two events.
Because of the great mass of the ‘waters above’, I could neglect the
smaller mass of all the galaxies in deriving the metric. Although other distributions
of mass could also solve the Pioneer mystery, this one seems more applicable to
biblical cosmology.
Being relatively simple, the new metric clarifies a new type of time dilation that
was implicit in previous metrics but obscured by the effects of motion. This new
type, which I call achronicity, or ‘timelessness’, affects
not only the narrow volume of space at or just around an ‘event horizon’
(the critical radius around a black hole at which time stops), but all the volume
within the horizon. Within an achronous region, we will see, time is completely
stopped. I pointed out a related effect, ‘signature change,’ in an earlier
paper,8 but all I had to
go on then was an older metric, the Klein metric, which was quite complicated. The
complexity obscured what that metric suggested could happen to time. The cosmology
this paper outlines is a new one that does not stem from the Klein metric.
The new metric
A metric specifies the spacetime interval ds between two events in time
and space. When ds is ‘timelike’ (i.e. a real number according
to the sign convention I’m using), it is simply c multiplied by the
time interval a physical clock would read when moving with the correct speed to
cross two events close to each other in space and time:
where dτ is the time interval read out by the clock. The time τ
registered by a physical clock (in its rest frame, of course) is called proper time.
Figure 2 shows the two events, 1 and 2, a time dt and distance dw
apart. As all metrics do, my metric shows how to calculate the spacetime interval
ds in a specific situation:9
Here dt2 and dw2 ≡ dx2
dy2 dz2 are the squares of coordinate
time and distance intervals, that is, time and length as measured by very distant
clocks and rulers where Φ is zero. Notice that dw is not a radial distance
interval, but rather a total distance interval with components dx,
dy, and dz. So this metric differs from the similar Schwarzschild
metric I show later in eq. (16).10
In this metric, eq. (2), Φ is the gravitational potential11 at any point inside an empty spherical shell of
mass M and radius R:
Figure 4. Heavy ring on trampoline illustrates gravitational potential
‘well’.
The radius R can depend on time, making Φ depend on time, and yet metric
(2) will still be an exact solution of Einstein’s gravitational field equations.
Notice that the potential is a negative number. As applied in this paper, R
is the radius (many billions of light-years) of the spherical shell of ‘waters
that are above the heavens’ I mentioned in the introduction. As I said in
the introduction, R increases with the expansion of space. Eq. (3) shows
that as R increases, the potential will get less negative. Figure 3 illustrates
that increase.
Figure 4 shows an analogy from everyday life, a heavy ring on a backyard trampoline.
The two-dimensional ring corresponds to the three-dimensional mass shell of radius
R in figures 1 and 3. The dent the ring makes in the fabric of the trampoline
has a similar cross-sectional shape as the potential ‘well’ in figure
3. Notice that inside the ring, the trampoline fabric is flat, just as the potential
inside R is flat. If we make the ring have a larger diameter, while keeping
its weight the same, the dent in the trampoline will get shallower, just as the
potential well in figure 3 gets shallower as the radius R gets larger.
Time dilation with the new metric
The metric of eqs. (2) and (3) is exact even for R (hence Φ) changing
with time, and for large potentials, even deeper than –c2.
This exactness allows us to deduce how time dilation depends on gravitational potential
and velocity. In terms of coordinate distance and coordinate time, the velocity
of the moving clock in figure 2 is:
Insert (1) into (2), divide by c2, factor out dt2,
and use (4) to replace dw/dt:
Take the square root of (5) to get the proper time an object moving with velocity
v experiences during an interval of coordinate time dt. That gives
us the time dilation:
Notice that for Φ = 0, this equation becomes the velocity time dilation of special
relativity:
Eq. (6) is a more general expression, combining the effect of velocity with the
effect of gravitational potential.
Time dilation for objects at rest
Consider what happens to a motionless particle. Insert
v = 0 into (6). Then the equation gives a purely gravitational time dilation:
Keep in mind that the potential Φ is a negative number. For shallow potentials,
that is, for –c2 << Φ ≤ 0, eq. (8) reduces
to a simple approximation found in many textbooks:12,13
Figure 5. Time dilation depends on depth of gravitational potential
F.
Notice that the factor 2 disappears along with the square root. Eq. (8) is more
useful than eq. (9), because the former is exact even for deep potentials. When
the potential is above the critical potential (that is, Φ > Fc,
where Φc ≡ −½ c2),
the expression under the radical (the radicand) in eq. (8) is a positive number.
Then proper time τ elapses normally for the particle, but τ
becomes slower (with respect to coordinate time t) as Φ approaches
the critical potential from above (figure 5). When Φ is exactly at the critical
potential, the proper time interval becomes zero. At that point, clocks that are
at rest (with respect to the centre) stop.
But what happens as Φ drops below the critical potential, so that Φ
< Φc? Then the radicand is negative, and we have the
proper time interval being the square root of a negative number. That means dτ
is a mathematically imaginary number. This suggests that in this region, physical
clocks would stop completely. Time would no longer exist. Regions of space below
the critical gravitational potential would be achronous.
Achronicity is more extensive than the more familiar kind of time dilation, because
the former stops time not in a very narrow region (say just around the event horizon
of a black hole) where Φ is close to the critical potential, but throughout
possibly vast regions of space, wherever Φ is less than the critical potential.
This makes achronicity a much more useful effect for creation cosmology.
The speed of light controls time
This section shows how achronicity is related to the coordinate speed of
light, which gives the coordinate distance dw a photon travels during a
proper time interval dτ measured by a physical clock at rest in the
coordinate frame. (The usual speed of light we measure is different; it gives the
physical ruler distance a photon travels during a proper time interval.) In my previous
paper,14 I showed that
the coordinate speed of light uc with my metric is:
The coordinate speed of light is not constant. It can vary from place to place and
time to time. That is the underlying cause of the ‘Pioneer anomaly’,
according to my previous paper.15
Most important here: if Φ drops below the critical potential, uc
will become imaginary.
Figure 6. Light-and-mirror clock. Pulsed laser at left makes very
short pulse of light. Light enters hole in mirror A and bounces off 99% silvered
mirror B, then off mirror A, and so forth many times. Each bounce from mirror B
passes 1% of the light pulse through mirror B to photoelectric detector behind it.
Output of detector is a series of electrical pulses. Time between output pulses
depends on the distance between mirrors and on the speed of light.
Thus in regions of space that are below the critical potential, light cannot propagate.
This (as well as many other relativistic effects) suggests a deep connection between
the coordinate speed of light and the flow of time. Here are a few reasons for such
a connection:
Figure 6 is a diagram of one of the simplest clocks I can imagine, a light pulse
bouncing between two mirrors.16
In a timeless region with no motion of photons, this clock would stop. Simple mechanical
clocks depend on c the same way.17
The speed of light appears to affect all physical processes we understand in the
same way. For example, in the relativistic generalization of classical electrodynamics,
electric and magnetic forces are proportional to the coordinate speed of light,18 thus becoming zero or imaginary
when the speed becomes zero or imaginary. Or, if you prefer the quantum-mechanical
description of electromagnetic forces, particles in an achronous region could not
exchange ‘virtual’ photons (the photons being unable to propagate),
so they could not interact. No interaction and no forces mean no physical processes
and no activity—no time. Thus the coordinate speed of light controls time.
The fabric of space controls the speed of light
Let’s examine what would cause the coordinate speed of light in eq. (10) to
become imaginary. Regarding space itself as a real but intangible material,19 which for biblical reasons20 I call ‘the fabric
of space’, Einstein’s famous equation E = mc2
suggests a way we can understand. Solve the equation for c and change c
to uc :
where I am regarding E as the energy of a small volume of the fabric of
space and m as the inertial mass of the same volume element. Dividing both
quantities by the volume gives
where ε is the energy density and ρ is the mass density
of the fabric of space at the location. Because Einstein’s equation appears
to apply to all forms of energy, I take ε as the total
energy density of the volume element. If we are motionless with respect to the fabric
of space, the fabric has no kinetic energy in our reference frame. That leaves only
the rest mass energy density and the gravitational energy density V of
the volume element as the remaining parts of the energy density ε:
Write the gravitational energy density V in terms of the mass density ρ
of the volume element and the gravitational potential Φ:
The factor of two is common in relativistic expressions involving potential. For
example, it is necessary to get eq. (9) from eq. (8). John A. Wheeler and his colleagues
have some interesting comments on this and a relativistic generalization of the
concept of gravitational potential.21
Use (14) in (13) and insert the result into (12):
This result is the same as eq. (10). The derivation suggests that the coordinate
speed of light in a region depends on the total energy per unit mass of the fabric
of space in that location. When the gravitational energy of the fabric is negative
enough to overcome all other contributions to its energy, light waves can no longer
propagate in the fabric, and low-speed physical processes stop. We could regard
this effect as a phase change in the fabric of space, analogous to the
thermodynamic phase change that occurs when water freezes. The Appendix explains
an analogy to this stopping of waves from everyday experience, making a connection
between energy density and tension.
Achronicity in previous metrics
The Schwarzschild metric (called his ‘exterior’ metric) I mentioned
in the introduction is:
where m is the mass of a non-spinning spherical object at rest, t
is the coordinate time, r is a radial coordinate from the centre of the
object to a field point in empty space outside the object, and the angles (θ,
φ) are colatitude and azimuth. (Outside such an object, the potential
and fields are static, and so cannot be applied to the problem of an expanding cosmos
with moving masses.) For a clock at rest with respect to the centre of mass, dr,
dθ, and dφ are all zero. Using those values and eq.
(1) in eq. (16), and then taking the square root gives the time dilation of the
motionless clock:
which is the same as eq. (8) with Φ =−Gm/r. For r
inside the Schwarzschild radius, rs ≡ 2Gm/c2,
i.e. inside the ‘event horizon’ of a black hole but outside the mass,
the radicand is negative. So if a particle inside rs (but outside
the mass) could be motionless, it would experience achronicity. However, most relativists
think it is impossible for an object to have zero velocity inside the event horizon,
partly because they want to avoid the possibility of the spacetime interval ds
being imaginary, (i.e. achronicity).22
Certainly it is quite plausible that the radial velocity of an object would not
be zero in the vicinity of the event horizon, because for small and medium-size
black holes the acceleration of gravity just outside the Schwarzschild radius would
be high (that is, the slope of space is high).23
In other words, the slope of space in the region is steep. So any object falling
into the black hole would have a high speed in the vicinity of rs.
In that case, v in eq. (6) would be high, allowing dτ to be
real even below the critical potential. In other words, the steep slope of space
near rs prevents us from using black holes to detect achronicity,
allowing relativists to avoid thinking about that possibility. But the new metric,
eq. (2), and its associated time dilation, eq. (6), apply to flat space.
That allows objects to be motionless, and thus it confronts us with the question:
what happens to motionless objects below the critical potential? The answer I am
offering is that time stops.
From 1994 to 2006,24 I
was using another metric derived by Oskar Klein in 1961.25 That metric is quite complicated, because in it
the fabric of space is usually moving quite rapidly. That means the kinetic energy
of the ‘fabric’ is not negligible compared to its rest mass energy and
its gravitational potential energy. Even so, under some conditions, all four terms
in the metric would turn negative, in which case clocks would be completely stopped
regardless of their velocity. The technical term for that phenomenon is signature
change. In 1998 I pointed out the possibility of signature change in the
Klein metric and the possibility of timelessness.8 But this new metric,
being simpler, makes the implication of achronicity much clearer. The next few sections
outline one scenario showing how timelessness could explain many cosmological observations.
Other forms of the new metric and cosmic redshifts
For cosmology calculations, it is helpful to transform my new metric, eq. (2), into
a form similar to the flat or closed-space versions of the Robertson–Walker
(RW) metric, the basis of the big bang family of cosmologies.26 First write the distance interval dw
in eq. (2) in terms of dimensionless spherical coordinates (χ, θ,
φ) that move along with the expansion, as if they were painted onto
a rubber sheet that is being stretched out along with the shell of waters of radius
R:
These (χ, θ, φ) are co-moving
coordinates just like the ones the RW metric uses. Now use eq. (18b) to replace
dw2 in eq. (2). Then make the transformations
and substitute them into the modified eq. (2). That gives us an RW-like form:
This differs from the RW metric in a very important way: below the critical potential,
and S2 change sign. However, eq. (20) has the same
outward form as the RW metric, so we can, with care, use results derived from the
RW metric. For photon trajectories that remain in regions entirely above the critical
potential, we can use the textbook derivation27
to get the cosmological redshift implied by eq. (20). That results in a wavelength
ratio of:
where l is the wavelength, Φ is the gravitational potential, S is the
overall scale factor, R is the radius of the mass shell, and the subscripts
1 and 2 refer to the times of photon emission and reception, respectively. If the
potentials at the time and place of emission and reception happen to be the same,
eq. (21) reduces to the big bang result. If there is a difference of potential between
emission and reception, the redshifts for a constant expansion rate would appear
the same as if there had been either an acceleration of deceleration of the expansion.
Thus it is easy to have scenarios giving the same redshift-distance relation as
the current ‘accelerating’ big bang models. That could do away with
not only the need for acceleration of expansion, but also the need for ‘dark
matter’ and ‘dark energy’.
Last, insert the following transformation,
into eq. (20), giving the metric in a simple form:
This form implies that if, in regions that are above the critical potential, we
plot photon trajectories on a graph with coordinates and, the photon paths will
be straight lines inclined at ± 45° angles to the horizontal axis. In
the next two sections I will take advantage of that convenient feature to make a
spacetime graph explaining how light from distant galaxies could have arrived on
Earth quickly, as measured by earth’s clocks.
A fourth-day light transit-time scenario
In this section I outline a speculative light transit-time scenario during Day 4.
Other scenarios are possible, so you should take this as only an example
of the possibilities that achronicity opens up.
Figure 7. Rising critical potential level makes achronous region
expand with velocity vt.
Imagine that events prior to Day 4 have expanded space and moved the shell of ‘waters
above the heavens’ out to a radius of, say, one billion light-years.28 Say that this has left
the earth and the nearly-flat fabric of space within the waters just above the critical
potential.
Now imagine that during the fourth day, God creates star masses in a way that would
create a linearly-dented perturbation29
in the otherwise flat potential of the fabric of space, as shown in figure 7. There
appear to be several ways to make such a shape.30
But the linear shape is not essential. It only makes illustrating the processes
simpler.
As in figure 5, the horizontal dashed line in figure 7 represents the critical potential,
Φc. As soon as God creates the galaxy masses, the fabric
of space begins sinking slowly, and the central part—containing the earth—will
drop below the critical potential. An observer in ordinary space a bit farther from
the centre would see a black sphere appear around the centre and begin growing in
size. According to eq. (8), the entire interior of the sphere is an achronous region.
For slow-moving objects in that region, time would be stopped.
The critical potential Φc depends on the speed of light, which in
turn depends on the tension in the fabric of space (see Appendix). If, as God stretches
out the fabric of space (e.g. Isaiah 40:22), He changes the tension simultaneously everywhere,
then c will change, and the position of the critical potential with respect
to the fabric will also change. (The potential difference ½ c2
is anchored to the Φ = 0 axis.) Thus the critical potential line in figure 7
could move up or down quite rapidly.
Let’s suppose the tension in the fabric of space suddenly decreases enough
to make the critical potential move upward rapidly. Then sphere of timelessness
will expand faster than otherwise. The speed vt of
its expansion (or later, contraction) will depend on three factors: the (inverse
of the) radial slope of the potential of the fabric of space (∂Φ/∂r),
the rate of the potential’s descent or rise (∂Φ/∂t),
and the rate of rise or descent (∂Φc/∂t)
of the critical potential level:
these factors being evaluated at the location of the surface. For general potential
shapes, let’s say that God designs or adjusts these three factors so that
the expansion speed vt of the timeless zone surface is exactly
c continuously. (Because the surface of the achronous zone is not a material
object, its speed is not limited.) For ∂Φ/∂r constant with
radius r, the other two factors can be constant in time to get a constant
vt. For vt = c, the timeless zone
will follow closely behind the wave of galaxy creation, also proceeding outward
at the speed of light. As the zone reaches and engulfs each new galaxy, time stops
for it.
When the sphere reaches zero radius and disappears, the Earth emerges, and immediately
the light that has been following the sphere will reach earth, even light that started
billions of light-years away
When the wave of creation stops, say at the location of the waters above, suppose
that God now increases the tension, and the critical potential line moves downward.
As it does so, the radius of the sphere of timelessness will decrease. Again, let’s
imagine that God sets the values of the three factors in eq. (24) to give a contraction
speed of –c. As each galaxy emerges from the receding timeless zone,
it resumes emitting light. Some of the emitted light will be going inward toward
the centre. Because the timeless sphere is moving inward at the speed of light,
the inbound light will follow right behind the sphere as it shrinks. When the sphere
reaches zero radius and disappears, the Earth emerges, and immediately the light
that has been following the sphere will reach earth, even light that started billions
of light years away. The stretching of the fabric of space has been occurring continuously
all along the light trajectory, thus red-shifting the light wavelengths according
to eq. (21).
On Earth, it is still only the fourth day. An observer on the night side of the
earth would see a black sky one instant, and a sky filled with stars the next instant.
With a telescope he would be able to see distant galaxies having suitably red-shifted
spectra.
A second time dilation episode during the Genesis Flood
Figure 8. Timeless zones enable galaxy light to arrive on Earth
quickly. Distance and cosmic time are the and of eq. (23). Units of light-years
for distance account for the factor c. Scale of the upper, light-coloured
timeless zone is exaggerated. Outward-curved trajectories of galaxies are due to
expansion of space.
As I have mentioned in several publications,31,32 two Bible verses lead me
to believe that there was a second space-stretching and time dilation episode sometime
during the year of the Genesis Flood. One of the verses is Psalm 18:9,
‘He bowed the heavens also and came down with thick darkness under
His feet [emphasis added].’
The other verse is 2 Samuel 22:10. It is identical, as the whole chapter is
nearly identical to all of Psalm 18. The repetition suggests that the psalm is quite
important. In it David reminisces about how the Lord has rescued him from dangers.
In this section of the psalm, he speaks in terms of a cataclysmic event that appears
to be the Genesis Flood. Everywhere else in Scripture, the phrase here translated
‘bowed the heavens’ is translated as ‘stretched out the heavens.’
The primary meaning of the Hebrew verb, natah, is ‘stretched.’
The translation ‘bowed’ is far down the list of possible secondary meanings.33 So I prefer the primary
meaning, which suggests that God stretched out space out at a higher-than-usual
speed (as measured on Earth) during the Genesis Flood.
Scientific considerations applying to the Flood suggest to me that time dilation
occurred during this event of space stretching, and it helps explain why the stretching
would appear to be very rapid as seen from Earth.34
Figure 8 is a spacetime diagram showing both time dilation events, one of large
spatial extent (gray region) occurring during Day 4, and the other of lesser extent
(upper, lighter-coloured triangular region) occurring 1656 years later during the
year of the Genesis Flood. The expansion and contraction of the lighter-coloured
region is slower than the speed of light, and it only extends out to, say, a few
hundred thousand light-years. At one instant during the flood year, if Noah could
have seen the night sky, its appearance would have changed suddenly. With a suitable
telescope, he would have seen the galaxies suddenly look roughly 500 Ma older (i.e.
spiral galaxies would be more wound up, etc.). The second dilation event, combined
with the speed-of-light recession speed of the achronous zone, explains why distant
galaxies, especially spiral galaxies, look no younger than nearby ones. This scenario
illustrates the usefulness of achronicity.
Conclusion
The new metric I derived in 2007 has yielded several interesting results. One is
a straightforward explanation of the Pioneer anomaly. In this paper, it has revealed
a new type of time dilation, achronicity. The fundamental cause of achronicity appears
to be that gravitational potential becomes so negative that the total energy density
of the fabric of space becomes negative. That stops the propagation of light, all
physical processes, and all physical clocks, thus stopping time itself.
I have examined the effect only for essentially motionless bodies (having velocities
very much less than that of light). In a later paper, I hope to explore some of
the interesting and possibly useful effects of achronicity for non-negligible particle
velocities. The speculative scenario in the previous two sections shows how useful
achronicity could be in creation cosmology. Other scenarios are easily possible,
and I hope that other creationists making alternative cosmologies will find timelessness
a good tool.
APPENDIX: An analogy from everyday experience
A stretched string35 (or
an elastic sheet36) propagates
transverse waves with a speed
where ρ is the mass per unit length (or area), and T is the
tension, the force (or the force per unit length) tending to pull the string (or
sheet) apart. I like to demonstrate this with a heavy cable (which has a high mass
per unit length) tied to a tree. Stand many metres away from the tree with the cable
lined up horizontally with your line of sight and pull the cable horizontally toward
you to give it some tension. Now give it a sharp jerk up and down, just once. You
will see a vertical pulse travel along the cable to the tree, bounce off it, and
return toward you.
The harder you pull the cable toward you, increasing the tension, the faster the
pulse will travel. If you decrease the tension, the wave travels slower. If you
did the experiment in space, in zero gravity, you could decrease the tension to
zero and the cable would not droop. But with zero tension, the wave speed would
be zero.
If, still in space with no gravity, you then pushed on the end of the cable
a little, you would be applying negative tension, i.e. pressure, upon it.
The cable might bend a little, but there would be no force trying to restore it
to straightness. That means transverse motions would not move along the cable, resulting
in no wave propagation. The transverse wave velocity us
in eq. (A1) would be mathematically imaginary. Just as negative tension in the cable
(or sheet) stops waves from propagating along it, so also negative total energy
in the fabric of space stops light from propagating through it.
Table 1. Analogy between transverse mechanical waves and electromagnetic
waves.
Thus there is a close correspondence between eqs. (12) and (A1), and the meaning
of a negative radicand in the two equations is the same—no wave motion. Table
A1 summarizes the analogy between the two equations.
Notice that the energy density ε at the top of the right-hand column
is analogous to the tension T in the previous two columns. For the 3D fabric
of space, dimensional analysis shows that the units of tension (Newtons per square
metre) are the same as the units of energy density (Joules per cubic metre). So
this analogy makes a connection between the tension in a fabric and the total energy
density of space.
The analogy extends even further. As figures 3 and 4 showed, there is a close correlation
between the depression caused by a weight on a two-dimensional stretched membrane
and the potential in Newtonian (three-dimensional) or Einsteinian (four-dimensional)
gravity. I have found this analogy to be very fruitful in understanding the physical
meaning behind the mathematics of general relativity.

- Gravitational potential Φ at a point is the energy needed
to lift a unit test mass from the point up to a reference location where Φ is
defined as zero. In this paper the reference location is far outside the shell of
waters (the potential approaches zero inversely with distance in that region) and
thus far above all other mass in the cosmos. Return to text.

- Landau and Lifshitz, ref. 12, pp 257–258. Note that
h ≡ g00 = coordinate speed of light squared,
and note the last sentence on p. 258, saying that in this case both the electric
permittivity ε0 and magnetic permeability µ0
of space are both equal to 1/√ h. That means, for example, that the
factor 1/4p ε0 in the SI form of the Coulomb force equation
is proportional to the coordinate speed of light. Return to text.

- It is not hard to show that a small perturbation added to
the flat potential of eq. (3) and then used in metric (2) is at least an approximate
solution of the Einstein field equations, as it would be for the Newtonian equations.
Thus the perturbed-potential metric would have the same general features as the
flat metric, particularly having the possibility of achronous regions.

- Humphreys, ref. 1, p. 69, end note 25. One way to make a
linear dent in the potential, according to rough calculations of mine, is to create
the galaxies in a wave proceeding outward from the centre at the speed of light.
Another way is to create all the galaxies simultaneously with a number density decreasing
inversely with distance away from the centre. As I mentioned in the text, the linearity
of the dent is not necessary; it only makes the illustration simpler.
