Until the early twentieth century cosmology was not even considered
a science. Most of cosmology deals with events so far in distant time
and space that it was generally accepted that everything had to be simple
conjecture or hypothesis, that nothing could be proven by such a scrupulous
test as the scientific method.
But around 1929, when Edwin Hubble published his
correlations of red-shift in starlight against distance of those stars
from earth, cosmologists almost immediately began to celebrate that
this not only proved the predicted expanding universe but elevated cosmology
from conjecture into true science. As you might expect, since that time
cosmologists will do and say almost anything to maintain that status
in the scientific community.
And since that time cosmologists have constructed
a magnificent array of speculation, observations and hypotheses, called
Big Bang theory, to describe the origin of the universe. But is that
array true science? What can we say we “know”?
The Scientific Method is defined as a process: (1)
ask a question; (2) do some background research; (3) construct an hypothesis;
(4) test with experiments; and (5) analyze results and draw conclusions.
Regarding the question (step 1) of the origin of the universe, cosmologists
studied (step 2) what they could see and properly interpret of the surrounding
stars and galaxies; and formed the hypothesis (step 3) called the Big
Bang. But it was and still is quite clear that nobody was ever “back
there” 14 billion years ago to observe and take data and no one
has ever created those conditions to experimentally prove the hypothesis
(step 4). Red shift alone does not prove an expanding universe. As a
result, the hypothesis known as the Big Bang has never been proven.
If cosmology is a true science it seems clear cosmologists cannot say
they actually know anything about the origin of the universe. They must
admit that Big Bang theory is still little more than hypothesis, and
that your guess might well be as good as theirs.
Nevertheless, it seems worthwhile to look into and
describe Big Bang theory and to point out the large number of unsupported
assumptions that had to be made along the way to make the theory fit
together at all. The assumptions are numbered as we go along. Some will
be discussed more than others:
| |
Assumption (1): An initial point source of all the energy of the
universe (no mass) originated from “nothingness” (was
not “created”). What is a “nothingness”,
does it / can it have scientific meaning? Has “nothingness”
ever been tested?
(2): That initial point source apparently was
not contained within anything, it was space curved in upon itself,
so there was never a boundary between that space and the surrounding
“nothingness”. “Something” not really embedded
in “nothing”? Impossible even to conjure a picture of
that, and there certainly is no “proof”.
(3) For a very short period (one 10-34th of a
second) that energy concentration expanded (faster than the speed
of light) into a very large volume -- then settled down into slower
(than the speed of light) expansion. This assumption was developed
to “explain” a strong inconsistency in Big Bang theory
-- the un-curved “flatness” problem.
(4) The relatively uniform concentration of energy
in that newly expanded, massive universe “condensed”
out into recognizable masses like hydrogen and helium atoms, and
then into stars and galaxies. Recognizable -- why?
(5) In all of (4) there is no explanation for
how those billions and quadrillions of identical atoms formed --
even at totally unconnected, opposite ends of that massively expanded
universe.
(6) In addition, in (4), there seems to be no
explanation for how the highly complex, distinctive order of these
masses was created from the initial total disorder of the energy
concentration. One simple form of the Second Law of Thermodynamics
indicates that order always goes to less order, to greater disorder,
never the other way around. More on this below.
(7) The galaxy-filled universe began the slow,
steady (Einsteinian) expansion said to be described by the observed
red-shift in starlight. This is really what is thought of as Big
Bang theory, all the previous is necessary simply to set up the
“proper” initial conditions -- an extremely large universe
full of recognizable atoms, molecules, stars and galaxies, expanding
at some rate slower than the speed of light.
(8) To use red-shift to describe universal expansion
it had to be assumed that the light would radiate from the atoms
and molecules at frequencies identical to those recognizable here
on earth today.
(9) That initial universe was so large that the
masses, stars and galaxies were represented (mathematically) as
nothing more than point sources of gravitation, with no specific
physical dimensions. But assumption (8) seems to mean that those
masses actually had to be the same physical size at the beginning
of time, when first formed, as they are at the end, here on earth
today. If they had been formed at very small sizes and expanded
along with the surrounding space one would expect at first to see
much higher radiation frequencies (shorter wavelengths). What we
see is the opposite. So in order for the degree of red-shift in
starlight to give us a measure of the expansion of space at that
time it was necessary to assume that in our universe it is space
that is expanding and physical dimension are not. Well, of course,
there is no supporting evidence or reasoning to suggest this. Aren’t
masses mostly space? What is it within a galaxy that could make
it maintain a fixed physical size while the space it occupies gradually
expands out from under it.
(10) With assumption (9) it can now be assumed
that the speed of light is exactly constant, compared to these (assumed)
constant physical dimensions (like the earth) and is therefore independent
of time, for all time. More on this below. |
In addition, as Big Bang research and development progressed several
new observations suggested that the whole theory might not be valid.
Rather than accept that conclusion, cosmologists seem to have struggled
(almost frantically?) to explain away these anomalies. But in each case,
to sustain Big Bang theory, they seem to have had to come up with even
more totally unsupported, conjectural assumptions. Most scientists seem
to agree that Einsteinian General Relativity best describes the physics
of the expanding universe, but those equations suggest that within that
ball space is curved. Well that should be relatively easy to experimentally
“check out”, even here on earth today. However, after massive
efforts by many scientists over the years, using various techniques
and the most powerful telescopes available, space always turns out to
be flat, not curved.
There is still the possibility that space has been
and will be curved but that our universe today is perched right on the
razor edge between one that will stop expanding and fall back on itself
and one that will continue to expand forever. A way outside possibility?
So, what is that as yet unobserved phenomenon that
is causing the universe to appear flat? In 1981 Alan Guth proposed that
in an extremely short time (10-34 seconds) after the very beginning
of the universe (just after time zero) that hot little ball of a universe
exploded, at many times the speed of light (compared to what?), until
it became so large that the curvature could not be detected here on
earth today. Of course, all this was said to have occurred before any
light could ever reach us here on earth so there is not and cannot be
any way to verify or support such an hypothesis. There seems no way
that Guth’s universal expansion could ever be considered a legitimate
part of science. All of this is assumption (3)
Then as time went on and cosmologists continued to study the expanding
universe another inconsistency popped up. It soon became apparent that,
based on phenomena such as the speeds of rotation and evolution of galaxies
and “gravitational lensing”, there was simply not enough
distinguishable matter in the universe. It is said that only some 4
percent of the total energy density of the universe can actually be
seen. So what is that as yet unobserved mass that is controlling the
activity and evolution of the expanding universe? That question becomes
[assumption (11)], “What / where is that additional, unobservable
Dark Mass?
But hardly had cosmology accepted the “dark”
word than there arose a conflict between those continuing to study and
refine Hubble’s linear relation between red-shift and distance
and those studying the formation and age of stars. The more scientists
refined the Hubble correlation the more they began to conclude that
the universe can only be some eight billion years old. At the same time
the star formation people were becoming more and more sure that the
oldest stars in the universe were more than fourteen billion years old.
After a few years, cosmologists began to conclude [assumption (12)]
that the universe had been expanding much more slowly in the early years
and was only now accelerating. That would increase the apparent age
of the universe.
But that now created the question of what has been
causing that expansion to speed up? It wasn’t long before someone
came up with the (again totally unsupported) idea [assumption (13)]
that the cause had to be some unseen, unknown anti-gravity energy out
there that becomes stronger as the universe gets larger. With a few
mathematical manipulations the Dark Energy concept was adjusted until
there was good agreement between the Hubble people and the “star-age”
people. Today it is said that some 74 percent of the energy density
of the universe is considered to be “dark”.
Of course, all of these numbers were developed using
the unsupported assumptions mentioned above. Is it possible that under
a different set of assumptions all “dark” stuff would go
away?
Note that, from the standpoint of science, the very
word “dark” means “unknown”. Such a term is
not “falsifiable”, it should immediately trigger the additional
scientific statement that whatever these “dark things” are
they simply cannot be considered a true part of science -- they are
little more than pure conjecture. Discussions of science and the scientific
method should never include the word “dark”.
All but two of these assumptions (6 and 10) seem
simple enough to understand, to recognize how each is almost totally
unsupported and are little more than hypotheses. Those two are discussed
further below.
Order
to Disorder (6)
The Second Law has a number of thermodynamic applications
but in one form it says, in effect, that within a closed system (like
the universe) order always proceeds to disorder, never the reverse.
There is a special term (“entropy”) that defines the level
of disorder in a closed system -- zero entropy is perfect order, infinite
entropy is complete disorder. A simple example is a two-story house
of cards (low entropy)-- you could stare at it all day but it will never,
by itself, create a third story (move to even lower entropy). On the
other hand, the slightest disturbance will send it tumbling down into
a totally disorganized pile of cards (very high entropy).
The Second Law is perhaps the most thoroughly proven
law of science -- it is demonstrated thousands of times a day in hundreds
of applications, and is never wrong -- order always goes to disorder.
But early Big Bang theory (origin) seems to indicate
just the opposite. Shortly after the Guth “super expansion”,
atoms, electrons, and molecules like hydrogen and helium began to form
and clump together, then forming trillions of stars and billions of
galaxies. That, of course, represents a dramatic increase in order throughout
the universe (adding a massive number of stories to the house of cards),
in direct violation of the Second Law. Furthermore, that increasing
order includes the formation of a wide range of molecules all neatly
arrayed in accord with what would later be called the Periodic Table.
Where were the blueprints for those complex structures,
what caused only hydrogen and helium to form? And how could these new
elements know enough to line themselves up in accordance with the Periodic
Table? And this spontaneous creation of complex order from total disorder
in the expanding universe is even said to have occurred simultaneously
throughout that nascent universe, identically so even in parts of that
universe no longer in contact with each other.
That’s the problem with violating the Second
Law, before you form anything truly more ordered you have to have assembly
instructions and/or blueprints. To accidentally form one kind of amazing
new order one moment and then form several entirely different kinds
of amazing order at later times -- is still creating disorder. On the
other hand, if order is proceeding to disorder (the house of cards is
falling down) you don’t need any kind of planning.
Some scientists delight in extrapolating that Second
Law into the very distant future to show, beyond doubt, that the universe
will eventually end in total meaningless disorder. However, another
very important aspect of the Second Law is that same extrapolation in
the opposite direction, into the deep, dark past. With the same lack
of doubt this extrapolation predicts a universe in the very distant
past in perfect order (zero entropy).
A universe in perfect order suggests one in which,
such like the Big Bang concept, all energy is concentrated at one point.
But, unlike the Big Bang, there is a “rest of the universe”,
and that space is totally without energy. In addition, to be in perfect
order, that energy-filled point must be in instantaneous contact with
all the rest of the universe, totally available to do work, to create
time, to “make things happen” -- everywhere. Does that sound
like the Big Bang hypothesis?
Speed
of Light (10)
When Einstein first postulated that the speed of
light is everywhere constant he did not specifically hypothesize that
it has been exactly that same speed for all time. One could argue that
it was the Russian Alexander Friedman, in 1922, who first came up with
that “truth”. Alex probably found himself (mathematically)
unable to solve Einstein’s tensor equations for the universe if
he had to carry either the speed of light or the dimensions of the physical
matter as a function of time. -- all had to be exactly as seen here
on earth today, back to the very beginning of time. The mathematics
was simply not otherwise solvable.
Introducing those simple mathematical gimmicks he
was able to solve Einstein’s equations for the universe. His solution,
then, showed that space had to be curved and that the spatial (but not
the physical) universe has been expanding with time.
For seven years Friedman’s expanding universe
was broadly discounted. Even Einstein ridiculed him, stating that everyone
knew that the universe was not expanding, it is static and has been
so forever. Einstein even threw another mathematical gimmick into his
equations to cancel out any universal expansion.
Friedman and his friends and supporters searched
diligently for experimental support -- anything! Then, in 1929, they
heard that Edwin Hubble had discovered that red-shift in starlight increases
linearly with distance from earth. It was no problem for Friedman and
company to make the further assumption that red-shift is the result
of a Doppler-like effect due to movement of the light sources away from
earth.
With that, cosmologists were convinced that they
now had their “irrefutable experimental proof” that the
universe is indeed expanding. And that means, of course, that the speed
of light is indeed independent of time. Even Einstein finally surrendered,
indicating that he may have made the worst mistake of his life. This
was considered a necessary, almost critical conclusion not just to confirm
the expanding universe concept but to raise cosmology from the world
of conjecture and hypothesis into the respectable, substantiated world
of science (experimental proof!).
And so it became critically important to solidly
establish that Hubble’s red-shift / distance correlation did in
fact prove that the universe is expanding. Ever since that date, and
even today, almost every paper on the Big Bang begins with the stock
sentence, “In 1929 the great Edwin Hubble discovered that the
universe is expanding.” The word “great”, of course,
provides stature and believability and the word “discover”
suggests that this expansion was not a scientific hypothesis or theory
but an actual fact simply “discovered” by the great Edwin.
What Edwin actually discovered, and experimentally
verified, was nothing more than the fact that the degree of red-shift
measured in starlight is linearly related to the distance of those stars
from earth. Hubble himself went to his grave loudly proclaiming that
his experimental results did not prove an expanding universe.
Ever since that time cosmologists seem to carefully
avoid the fact that their connection between Hubble’s red-shift
/ distance correlation and an expanding universe interpretation hangs
on those two critical unsupported assumptions, that the speed of light
is independent of time and that the red-shift can only be caused by
some sort of relative motion of the light source away from earth. And
it is certainly not science to now twist that around to suggest that
the expanding universe (a “fact” discovered by the great
Edwin Hubble) proves the validity of those two assumptions.
A
Variable Speed of Light
Throughout this Big Bang discussion the point has
been made that the crucial assumption that the speed of light has been
constant for all time, that it is independent of any passage of time,
is simply not supported by experimental evidence. So what if we simply
do not make that assumption? Amazingly enough, another whole scientific
scenario for the beginning of the universe seems to emerge.
Hubble, of course, did not “discover”
that the universe is expanding, he discovered only that linear red-shift
/ distance correlation. We can use that relation (mathematically) to
tell us how the speed of light could have varied in the past. That simple
solution (no other assumptions) shows that since the “beginning”
the speed of light has been exponentially decreasing with time. That
means that at some time in the distant past it was very fast, so fast
that it could well have almost instantly reached the limits of space
no matter how big the space.
And, of course, in this “unspecified variation
in the speed of light with time” approach, it is no longer necessary
to make 12 of the above 13 assumptions. Time, space and all physical
dimensions are left exactly as seen here on earth today. Both would
have had to originate at some times and places [assumption (1)] but
those answers are clearly unknown.
Such a ‘variable speed of light’ scenario
offers a simple explanation for Olber’s Paradox, “Why is
the sky dark at night?”. The initial flash of light, at some finite
time in the past, traveling essentially at infinite speeds, filled all
the universe. But then, in accordance with the Second Law, the speed
of light began to decrease (exponentially) and the most distant stars
began to fade from view.
In the 14th century Friar William of Ockham propounded
what became famously known as Ockham’s Razor: “Entities
should not be multiplied beyond necessity.” In today’s world
that would more likely be verbalized as “Keep it simple, stupid!”
Clearly the variable speed of light scenario for the origin of the universe
(one unsupported assumption) follows Ockham’s Razor far better
than does the Big Bang hypothesis (13 unsupported assumptions).
Well, it
does seem that the current scientific explanation of the beginning of
all things, the Big Bang / expanding universe hypothesis, is based on
so many totally unsupported and extremely doubtful assumptions and definitions
that it is hard to imagine that science even considers that scenario
to lie within science. There seems to be little question that the hypothesis
does not survive examination by the scientific method.
The whole Big Bang scenario for the very beginning
of the universe seems a classic example of “Group Think”.
The professors who teach the Big Bang in the universities are the same
professors who “peer review” papers for publication, and
are often those who are consulted regarding research grants. New, young
researchers are fully aware that dissenting opinion will receive neither
research grants nor publication And so there continues to be no dissenting
opinion (except herein).
So, in this case, it appears that the reigning scientific
explanation simply cannot be considered part of what we can say we “know”.
It would even seem likely here that the universe (gulp) may not be Einsteinian.
On the other hand, there does seem to be a physical
scenario which science has not considered. That is the universe that
we can derive when we free the speed of light from the “constant
for all time” assumption. This approach does not require a massive
chain of unsupported assumptions to make it fit available physical observations;
there is no need for such things as dark mass and energy; and it best
satisfies both Olbers Paradox and Ockham’s Razor.
In cosmology, the Big Bang hypothesis represents
“the box” -- this is what we “know” today to
be “fact”. If science is ever to significantly expand the
horizons in cosmology, researchers must bring themselves to recognize
the “softness” of the walls of that box, and begin to think
beyond them -- outside of that box. One way seems to be simply to neglect
the assumption that the speed of light has been constant for all of
time.
