Distant starlight: It's been called the best
argument against biblical creation and a young universe.[1]
Why is
that? Because Big Bang Theorists, secularists and anyone who believes in
an ancient universe believe they have an iron clad case against a young
universe with regard to distant starlight. The argument goes like this.
The Problem
We can see stars hundreds of thousands,
millions even billions of light years away. Take the
Andromeda
galaxy - 2.5 million light years away. A
supernova was observed in that
galaxy. That implies the light took 2.5 million years to get to
earth. But if the earth (and indeed the entire universe) is only 6,000
years old. How can we see Andromeda or the supernova? Using standard
understandings and formulas, there hasn't been enough time for the light
to get here from Andromeda. Yet we can see it. On the face of it that
suggests that the earth is at least 2.5 million years old - much older
than the 6,000 years that Biblical creationists claim for the universe.
And the problem only gets worse for more distant stars. This is indeed an acknowledged problem.
Before we go on to look at some
suggested solutions, let's make sure we clearly understand the problem
by defining a key term: light year. A light year is the distance light
travels in one year. It's a measure of distance, not time. Scientists
use this notation to avoid dealing with the extremely large numbers that
would be necessary if distance units of miles or kilometers were
used instead. A light year, being a huge distance (5.88 trillion
miles) helps keep the numbers manageable. It's use is a convention used
for convenience. Keep that concept (of convention) in mind - we'll
come back to it.
So that's the problem. But it's not an
unsolvable problem. Following are some of the solutions offered by
creation scientists to allow distant starlight to be seen in a young
universe. You'll note there are a few. Can we identify the best
candidate? I think so. So in Part 1 of this article, we'll look at
popular suggested solutions. In Part 2, we'll use Occam's razor to see
if we can come up with the best solution.
Popular Suggested Solutions
Before we can evaluate the solutions we
must first know and understand what they are. Following are the most popular
solutions suggested. Some of them are complex and technical. In the interest of clarity and
brevity I will endeavor to present the salient points of the individual
solutions from a high level view with only enough detail to make the
theory clear enough to gauge viability.
Sources of Solutions:
For a moving object, the amount of distance covered in a given amount of
time is described by the equation:
Distance=(velocity) times (amount of
time travelling at the velocity)
or D=vt
Where:
D is the distance traveled - in this case from the stars to earth
v= velocity - in this case of light, commonly denoted as c, and
t= time elapsed - in this case amount of time the light has been
traveling
No physicist I'm aware of - secular,
creation or otherwise disputes the distances involved.[2] They all agree
the distances - as measured by the techniques available to scientists
today - are real and accurate. And as noted above they are huge - truly
astronomical. Thus no solution suggests a significantly smaller universe
that allows starlight to easily arrive on the fourth day. No, rather
distances are apparently the one constant in this problem that all agree
on - the distances as measured are real. Thus solutions tend to come
from one of the variables on the other side the equation: variations of
velocity and time - though there are exceptions.
Solutions suggested:
1)
A Variation in the starting point of light (Light created in transit)
This is based on the idea that the creation had to be functionally
mature for Adam and Eve. They needed fruit on their first day, not
months later after a harvest. To achieve this functional maturity Henry
Morris proposed that God created the light in transit. Thus since it did
not have to traverse the entire distance from the stars to earth, it was able to arrive on the
fourth day.
2) A (natural) variation in the
speed of light (CDK)
This theory suggests that the speed of light c was much greater
in the past, allowing for the light to arrive in the needed time frame
(the 4th day).
This has been suggested by physicists supporting both biblical (Barry
Setterfield) and secular (Joah Magueijo) theories, though they support
it for different reasons. (Setterfield to resolve the creation distant
light problem, Magueijo to resolve the Big Bang's
horizon problem.) This theory often
goes by the word play of CDK (c=speed of light; DK - sounds like decay
thus "speed of light decaying or slowing").
3)
A (supernatural) variation in the speed of light (Dasha)
Answers In Genesis staff astronomer and physicist Danny Faulkner puts
forth an elegantly simply proposal. The Bible depicts things
growing supernaturally fast during creation week as God prepares the earth for the crowning
glory of his creation: humans. (The Creation Today/Sevenfold Films
documentary Genesis Paradise Lost does
a good job of depicting this.)Just as the trees and plants must have
grown supernaturally fast on day 3, Faulkner suggests the light must
have arrived in a supernaturally fast manner on day 4. He offers no
explanation for how God does it, but he calls the
theory the "Dasha" theory based on how the Hebrew verb דשא "Dasha"
("bring forth" (KJV) or "produce" (NIV) is applied to its cognant
noun "Deshe" (vegetation) in Gen 1.11. And also probably
for the same reason the word play on the Tower of "Babel" became popular.
(Dasha sounds like "dash"=fast; babel sounds like "babble"=confusion.[3])
4)
Variations in the flow of time - (how fast clocks tick) (Time Dilation)
These solutions are based on Einstein's theories of Relativity.
Einstein predicted, and scientists have subsequently confirmed, that for
an observer in one frame of reference, time can move differently from an
observer in another frame of reference based on gravity, acceleration or
velocity. Two creation scientists have applied these principles in
different situations, but the concept and the result is the same: due to
relativistic time differences, clocks in the universe run multiple
millions[4] of time faster than clocks on earth. Key to these solutions
is the shape of the universe and the distribution of matter in it.
Whereas the Big bang requires a homogenous (evenly distributed) and
isotropic (the same in all directions) initial condition, Hartnett and
Humphreys describe a universe that is
isotropic, but spherically symmetric - not homogenous. This allows
time dilation as predicted by Einstein to work in Humphreys' and
Hartnett's models. The effect of the time dilation is to allow billions
of years to pass in the universe where the stars are, while only 24
hours pass on earth.
4a) Time Dilation: Russell Humphreys' Timeless Gravity
Well
Some call this a "white hole cosmology" but I prefer the gravity
well moniker because that concept is more familiar due to pictures like
this from NASA, and the fact that a gravity well is on the
cover of his DVD - a deep well with the stars added at the bottom -
a feature that is part of his theory. Humphreys pays close attention to the details of the creation
account, taking into account key clues such as the "deep" (Gen
1.2) and the "expanse" (Gen 1.6) Due to the extreme mass of the deep,
prior to the creation of the stars on day four, the earth sits just
above a critical point where more mass would push it into a timeless
zone. A timeless zone sounds feasible on the face of it since we know extreme masses like black holes can cause time to stop as
secular physicists also acknowledge.[5] To visualize what happens, picture a ring hanging by a string
held at both ends
just above a body of water. The ring represents the earth, the string
the flexible fabric of space, the water - the bottom of a gravity well - the point at where time stops. Before
God creates the stars on day 4, due to the mass of the deep the earth sits just above the timeless
zone represented by the water in the well. With the addition of the mass of the stars
added to
the string, the earth dips into the water - that is to say into the
timeless zone. At that point time stops on earth (yes you read correctly
- time stops on earth) - but continues in the
universe. Then God stretches the heavens (as declared in places like Is
40.22 and 42.5). Just as stretching a string with a ring on it would
make the ring rise, the stretching of space simultaneously pulls earth out of the timeless
zone and causes time dilation in the heavens - allowing billions of
years to pass in the realm of stars while one, 24 hour day passes on
earth.
4b) Time Dilation: John Hartnett's Carmelian physics identified Massive Expansion Event
Hartnett bases his theory on an addition to Einstein's physics made by
Moshe Carmeli. Carmeli provided a solution to the problem of the arms of distant Galaxies
rotating too fast (for Newtonian physics) - a problem currently solved
by the addition of theoretical dark matter. He solved it not by adding
unseen matter, but by adding an
additional degree of freedom through which our universe can move. Thus
instead of 4 dimensions, there are 5 in Carmelian physics. So where
Einstein speaks of the 4 dimensions of space and time as "space-time",
Carmeli speaks of the 5 dimensions of space, time and velocity as
"space-velocity". And as noted above, earth sits in the center of
a spherically symmetric isotropic universe. A special place with
regard to time and relativity.[6] In order for the universe to currently
be moving fast enough to make up the difference between the observed
speed of the galaxy arms and the predicted Newtonian speeds, Hartnett concluded,
"At some point in the past, the universe was rapidly expanded. By
rapidly expanded I mean accelerated. The fabric of space was rapidly
expanded. Now I can't tell you when that happened but when I read the
bible it seems like day 4 of the creation week seems like the perfect
opportunity for this time happen."[7]
This expansion would have been
accompanied by time dilation in the universe - brought
about by the expansion (or acceleration) of the fabric of space.
As in Humphrey's model the clocks on earth ticked much slower
(trillions of time slower) than clocks in space.
5)
A Variation in how we view the narrative and the one way speed of
light
Astrophysicist Jason Lisle takes a unique approach to the problem. His
solution has two unique components: 1) The descriptions in the Bible of
what happened during the creation week are based on the perspective of
what a person would see from earth. It does not account for what's
happening in the heavens (the universe). 2) The speed of light is not
the same in all directions. It is thus "anisotropic"
(directionally dependent). Specifically the speed of light when coming
towards an observer (on earth in this case) is infinite. Away from
observers it has the value of 1/2 the speed of light. Given
these two conditions, the light from distance stars would arrive
literally in no time - since light would be moving at an infinitely fast
velocity. Thus when God says "'...let them be lights in the
expanse of the sky to give light on the earth.' And it was so." (Gen
1.15) - the light was instantly visible once God created the stars. He
calls this approach the anisotropic or alternate synchrony
convention (ASC). (Here is the convention I told you to be mindful
of above. That this is a convention will be an important factor in its
evaluation.) This is opposed to the Einstein synchrony
convention (ESC) which is typically used. This ASC convention is one Einstein
indicated was valid; as do physicists today though it is rarely used.
6)
Star movement combined with a variation in the speed of light
Well known creationist Kent Hovind is not a physicist or scientist, but
his teachings on creation have been seen (and critiqued) by many. So it
seems they would fit the criteria of "popular" solutions. Hovind's
approach is to question what we think we know. (Are the distances to the
stars really that far, is the speed of light really constant?) He winds
up by saying the distances are probably real, but we don't know that the
speed of light is constant. Thus he posits that the speed of light
may have been faster in the past (like Setterfield), but his main thrust
is on the location of the stars upon initial creation. As does
Humphreys, he points to God stretching the heavens (Is 42.5), and says
the real question is "...not how did the light get from the star to
here, but how did the star get from here to there. That's the question
we need to be asking."[8] Thus the solution
appears to be a combination of a faster value for the speed of light (CDK)
combined with stars that started nearby (so light didn't have as far to
go) and then the fabric of space was stretched to get the stars where
they are now - allowing the stars to leave a trace of light during the
stretching.
Next up: Evaluation
This is admittedly a simplified version
of all theories involved, but I trust there's enough there to evaluate
strengths and weaknesses. Enough to allow us to use the current
understanding of physics combined with Occam's razor to choose the one
that most closely approximates what actually happened. We'll do
that critique and select the best candidate in Part 2 of this article.

2. In his discussion of the matter Kent Hovind questions scientists
ability to measure distance that involve billions of light years. But he
winds up stating the "stars probably are billions of light years away,
we just can't measure them." He's not a scientist but I mention it
because his (a combination of two solutions given by physicists) is one
of the solutions presented.

3. Note the English words in these word plays brings to mind meaning for
English speakers that is not present in the original Hebrew. The Hebrew
word Dasha (vegetation) - does not sound like "fast", but as noted Dasha
- sounds like Dash to an English speaker. The Hebrew word "Babel"
(Babylon) does not sound like "babble" (as one would experience if the
languages were multiplied leading to confusion) - but it does to an

Back 6. This is important because the center of a
spherically symmetrical universe is a special frame of reference where
clocks would tick slowly during an expansion event as Wikipedia notes:
"...gravitational time dilation is copresent with the existence of an
accelerated reference frame. An exception is the center of a concentric
distribution of matter, where there is no accelerated reference frame,
yet clocks are still supposed to tick slowly. " Wikipedia, Gravitational Time Dilation, accessed 5/21/19,
