Once
upon a time, people believed the sun, planets, and stars orbited a
stationary earth – an idea called, “geocentricism.” I'm sure
it seemed intuitive to everyone then because we certainly can't feel
the earth moving and the sun seems to move across the sky. In a real
sense, geocentricism seemed to explain the “evidence” well. Some
things, however, like the retrograde motion of planets, seemed to not
fit the theory well.
In
the second century, a Greek philosopher/astronomer named Ptolemy,
tried to smooth out the difficulties with geocentricism. He believed
the planets moved around the earth in an orbit called a deferent.
As the heavenly bodies moved in this large circle, they also moved
in a smaller circle called an epicycle around
an imaginary point called an equant. These ideas
seemed to address the observed problems with geocentricism well and
Ptolemy's theories endured until the time of Galileo.
Today,
we understand that the Sun is the center of our solar system and the
earth, as well as the other planets, orbit it. The apparent
retrograde motion of other planets is caused by a difference in the
relative speed of planets as they are observed from the earth.
Deferents, epicycles, and equants never existed at all! These
things were
the symptoms of a flawed theory. They seemed to answer some questions
about the theory but the real problems laid in the theory itself. So
as long as the underlying theory persisted, more and more fanciful
sub-theories had to be invented to keep the failed theory afloat. You
might call it them “fudge factors.”
So
where am I going with all this? Well, when it comes to secular
theories of cosmology, I've seen a lot of same behavior among
scientists. There are several crazy, er... I mean, “exotic”...
explanations that have been invoked in order to hammer down stubborn
difficulties with their theories. Actually, I'm only using the term
“exotic” to be nice. These theories are so insanely ridiculous
that I suspect that deep down even their most staunch proponents
don't sincerely believe them. They merely cling to them because
without them their entire worldview completely fails.
A
UNIVERSE WITHOUT EDGES
Imagine
for a moment a very large, flat meadow of grass with a crowd of
people standing in it. You are somewhere in the crowd. Through just
simple observation, it would not be hard to guess where you are in
the crowd. If all the people are on one side of you and no one on the
other, you would be on the very edge of the crowd. If there were more
people on one side than the other, you would be toward the edge. If
there were about the same number of people everywhere you looked, you
would be closer to the center. It's not hard, right?
As we
look around in the universe, we observe about the same number of
stars no matter which direction we look. Just as in my crowd analogy,
it would be very reasonable to conclude from this observation that we
are somewhere near the center of the universe. Of course, the
universe is very, very large and since we cannot see the edge of it
in any direction, it makes it hard to be sure that we're in the
center. It would be like being in the ocean with no land in sight;
you would really have no idea if you're in the middle of the ocean or
just outside sight of the shore. To really know we're in the center,
we'd have to have more information.
In
the mid-19th
century,
Dutch physicist, Christian Doppler noticed that sound waves changed
frequency relative to the observer when the source was in motion. He
dubbed this phenomenon, “the Doppler Effect” and believed it
would apply to all waves including light and radiometric waves. In
the beginning of the 20th
century,
we were able to observe this phenomenon in the light from distant
stars. The light from the stars was “redshifted” indicating that
the light wave was being stretched and that the star was moving away
from us. As we began to survey more and more stars, we realized that
the stars uniformly seemed to be moving away from us at a constant
speed.
The
implications of what was being observed was huge. Obviously it meant
the universe was expanding but more than that, the general movement
of the stars directly away from us further seemed to confirm our
position near the center of the universe. In this enormous universe,
the odds of us coincidentally being in the center are mind numbingly
small. If God had intended us to be in the center of the universe,
then the remote odds of it happening randomly don't matter. However,
scientists, because of their bias toward natural explanations will
not allow themselves to consider that we're here by design. So what
is the solution?
Scientists
have put forth a model of the universe where there really is no
center – or rather everywhere is the center. Space is a flat
surface that is being stretched like the surface of a balloon being
blown up. All points on the surface would be moving away from each
other yet there is no edge nor center to the universe. They say space
is curved, similar to the surface of the earth and if you started in
one direction and headed in a straight line, you would eventually end
up where you began. No matter where you are in the universe, we would
observe exactly the same things in every direction.
This
“Balloon Model” of the universe seems to be the epitomy of an
“exotic theory.” To me it seems way more far fetched than
Ptolemey's equants
and epicycles.
The mad genius of it is that really is no way to test it. There's no
way we could fly to edge of the universe to see if it's there. We
can't stand back from the universe and see if it resembles the
surface of a balloon. We can only picture the universe based upon we
can observe from the earth and that supports the Bible.
THE
OORT CLOUD
When
I was young, I used to think that comets hurtling through space were
similar to meteors entering earth's atmosphere; I pictured it as a
fiery ball with a long tail of flames. I know now that comets are
made of ice and the long tail we see is actually ice particles being
blasted away from the body of the comet as it passes near the sun.
The
fact that comets lose some of their mass each time they pass near the
sun has a bearing on the age-of-the-earth debate. Obviously, if a
comet becomes smaller with each orbit of the sun, eventually it must
disappear all together. Also, each time a comet comes near the sun,
it also risks collision with a planet or the sun itself which would
end its life immediately. Simple reason, then, forces us to
acknowledge that comets can only exist so long. Their long tails are
a visual testimony of their short livedness. Eventually, they will
either exhaust all of their matter or crash into a planet. If our
solar system were really billions of years old, they should all be
gone by now. End of story.
One
very famous comet is Halley's comet which passes by our sun once
every 75 years. It is consider a “short period,” one who's orbit
takes less than 200 years. Since Halley's orbit is only 75 years, in
just one million years it would have passed by the sun more than 13K
times! No one believes that is possible and I'm not suggesting that's
what secular scientists believe. Actually, secular scientists believe
the maximum life span of Halley is about 40,000 years. If the
universe is less than 10,000 years old, this isn't a problem at all.
However, it doesn't comport well with the idea that the solar system
is millions or billions of years old. If the solar system is really
billions of years old, why are there still so many short period
comets left? In order to rescue their theory, secular science must
find a source that can replenish comets as they are exhausted. After
all, since there still are comets, and we know that most of them
can't have been circling the sun for billions of years, these comets
had to come from somewhere more recently.
Secular
scientists are claiming a very exotic source of new short term comets
known as the Oort
Cloud.
According to Wikipedia,
the Oort cloud, “is
a theoretical
concept of
a cloud of predominantly icy planetesimals proposed
to surround the Sun at distances ranging from 2,000 to 200,000 AU
(0.03 to 3.2 light-years)”
[bold
added]. As
we read through the entire Wiki article, we see a lot of other
conditional descriptions; words like “conjecture,” “thought to
be,” and “hypothesized” abound. The Wiki article is brimming
with “facts” about the Oort cloud – things like it's
composition, size, origin, location, etc. It's amazing that we can
know so much about something that we've never seen and really aren't
sure even exists!
In
the same article, we can read the following:
“Over
the course of the Solar System's existence the orbits of comets are
unstable, and eventually dynamics dictate that a comet must either
collide with the Sun or a planet or be ejected from the Solar System
by planetary perturbations. Moreover, their volatile composition
means that as they repeatedly approach the Sun, radiation gradually
boils the volatiles off until the comet splits or develops an
insulating crust that prevents further outgassing. Thus, Oort
reasoned, a comet could not have formed while in its current orbit
and must have been held in an outer reservoir for almost all of
its existence.”
You
can read it for yourselves. The Oort cloud was hypothesized seemingly
for no reason other than the need for a source of comets! It about as
scientific as saying comets are made by unicorns. Most people agree
that science is founded upon observations. Here, we are talking about
a hypothetical source of comets that cannot be observed so their
belief is the Oort cloud is no more scientific than my belief in God.
The existence of the Oort cloud is simply necessitated by a belief in
an old universe. It's akin to a faith belief except they see it as
more plausible because it's a “natural” explanation rather than a
supernatural one.
INFLATION
COSMOLOGY
The
Big Bang model of the universe is a theory brimming with difficulties
– I mean difficulties beyond the obvious, “where
did all the matter come from.” The
problems I'm talking about are a little less obvious but still very
substantial. Please note too that these aren't my objections to the
theory. These are objections raised by secular scientists and
discussed in this
Wiki article.
The
Horizon Problem: If we looked toward the eastern sky, we could
see galaxies that are estimated to be 10 billion light years away. We
could see the same thing in the western sky. So if one galaxy is 10
billion light years away in one direction and another is 10 billion
light years in the other, then they would be 20 billion light years
apart from each other. Now, secular scientists date the universe to
be around 13.8 billion years old. Assuming that is true, the light
from the “eastern” most region of space has not had enough time
to reach the “western” region. Even though we can see both ends,
they should not be able to see each other because their light could
not have traveled the 20 billion light years of distance between them
in only 13.8 billion years. Are you still with me? OK. Here is the
problem: everywhere we look, the universe appears to be homogenous.
If
I dropped an ice cube into hot water, the cube would melt and the
water would cool a little. Eventually, it all becomes the same
temperature. That's homogeneity and it always happens eventually once
the two things begin to interact. It seems to have already happened
in the cosmos. The cosmic background microwave radiation, for example
is the nearly the same everywhere we look. But how could the entire
universe have evened out so uniformly if all the regions have not had
enough time to interact?
The
Flatness Problem: Matter produces gravity. Objects in motion have
kinetic energy. When the supposed Big Bang happened, matter began to
expand. Once the expansion began, kinetic energy would have carried
the matter forward while gravity would have been slowing the
expansion. Let me see if I can explain it in lay terms.
If
the rate of expansion were too slow, gravity would have quickly
pulled everything back into a Big Crunch. If the expansion were too
rapid, the matter would have accelerated too quickly for stars to
form. From the very beginning there must have been a perfect balance,
a “fine tuning,” between the expansion and the slowing or else
the universe could not exist as it is now. The precise balance of 1
is represented by the value Ω (omega). The margin is so narrow as to
be incredible.
These
Horizon problem and Flatness problem just two problems with a Big
Bang theory of the origin of the universe. While either one alone
could be fatal to the theory, scientists cling desparately to the
belief there had to be a solution. Enter now Inflation Cosmology!
It
was suggested in the 1980s that in the very early seconds after the
initial expansion, the universe when through short period of
hyper-expansion where it figuratively exploded from about the size of
a grape to trillions of miles across in just a fraction of a second.
They say such an event would solve a few difficulties.
First,
they suppose that the homogeneity we observe occurred prior to the
hyper-expansion, while all of space was still close together. When
inflation occurred, it carried the homogeneity out with it.
Concerning
the flatness problem, the inflation supposedly forced the value of Ω
to that fine-tuned balance of 1. Some have compared it to a how a
balloon smooths out as it inflates. I'm not sure how well the analogy
describes the solution but most cosmologists seemed satisfied with
it.
So
what is the evidence for all of this? We'll, it's pretty much like
the evidence for the Oort cloud – they simply need it for their
theory to be viable. It's a sort of fudge factor to get around some
of the serious difficulties they know exist with the Big Bang.
Actually, the idea of inflation is even less credible than the Oort
cloud. In the case of the Oort cloud, at least we know that icy
bodies exist in the universe. We've never seen an event like the
inflation epoch and there's nothing in physics that would otherwise
suggest such an event could or should occur.
CONCLUSION
When
we consider modern cosmology, the Big Bang doesn't sound unreasonable
at first hearing. We can see the stars moving away from us. If the
universe is continuously expanding, then we need only extrapolate
backward to conclude that at some point in the distant past, all
matter very close together. It's obvious. Yet no matter how
reasonable it sounds, some things just don't add up – things like
the flatness problem or the horizon problem. There's also the
unsettling coincidence that we appear to be at the very center of the
universe. Never mind there are still many other difficulties I don't
have time to discuss.
To
be certain, scientists have “explanations” for all these things.
They invent exotic theories to explain their failed predictions. It's
like epicycles all over again. However, unlike epicycles, we can't
test these fanciful cosmologies as easily. Scientists say that there
really is no center of the universe and it would look basically the
same from any vantage point. Really? How do we test that? We can't
even fly to the next star, let alone a star millions of light years
away, to see how the universe looks from there. We only know what the
universe looks like from our vantage point.
The
Big Bang theory is simply a modern version of Ptolemy. It might seem
reasonable at first but it is completely contrary to reality and can
only be kept afloat by continuously invoking very unreasonable
sub-theories. These sub-theories, though, lie outside scientific
inquiry. They can't really be observed or tested. They aren't as much
theories as they are stories. Secular scientists believe them not
because the scientific evidence for them is overwhelming but because
they refuse to consider the alternative.
