Big Bang Theory - The Premise
The
Big Bang theory is an effort to explain what happened at the very
beginning of our universe. Discoveries in astronomy and physics have
shown beyond a reasonable doubt that our universe did in fact have a
beginning. Prior to that moment there was nothing; during and after that
moment there was something: our universe. The big bang theory is an
effort to explain what happened during and after that moment.
According
to the standard theory, our universe sprang into existence as
"singularity" around 13.7 billion years ago. What is a "singularity" and
where does it come from? Well, to be honest, we don't know for sure.
Singularities are zones which defy our current understanding of physics.
They are thought to exist at the core of "black holes." Black holes are
areas of intense gravitational pressure. The pressure is thought to be
so intense that finite matter is actually squished into infinite density
(a mathematical concept which truly boggles the mind). These zones of
infinite density are called "singularities." Our universe is thought to
have begun as an infinitesimally small, infinitely hot, infinitely
dense, something - a singularity. Where did it come from? We don't know.
Why did it appear? We don't know.
After its initial appearance,
it apparently inflated (the "Big Bang"), expanded and cooled, going
from very, very small and very, very hot, to the size and temperature of
our current universe. It continues to expand and cool to this day and
we are inside of it: incredible creatures living on a unique planet,
circling a beautiful star clustered together with several hundred
billion other stars in a galaxy soaring through the cosmos, all of which
is inside of an expanding universe that began as an infinitesimal
singularity which appeared out of nowhere for reasons unknown. This is
the Big Bang theory.
Big Bang Theory - Common Misconceptions
There
are many misconceptions surrounding the Big Bang theory. For example,
we tend to imagine a giant explosion. Experts however say that there was
no explosion; there was (and continues to be) an expansion. Rather than
imagining a balloon popping and releasing its contents, imagine a
balloon expanding: an infinitesimally small balloon expanding to the
size of our current universe.
Another misconception is that we
tend to image the singularity as a little fireball appearing somewhere
in space. According to the many experts however, space didn't exist
prior to the Big Bang. Back in the late '60s and early '70s, when men
first walked upon the moon, "three British astrophysicists, Steven
Hawking, George Ellis, and Roger Penrose turned their attention to the
Theory of Relativity and its implications regarding our notions of time.
In 1968 and 1970, they published papers in which they extended
Einstein's Theory of General Relativity to include measurements of time
and space.1, 2 According to their calculations, time and space had a
finite beginning that corresponded to the origin of matter and energy."3
The singularity didn't appear in space; rather, space began inside of
the singularity. Prior to the singularity, nothing existed, not space,
time, matter, or energy - nothing. So where and in what did the
singularity appear if not in space? We don't know. We don't know where
it came from, why it's here, or even where it is. All we really know is
that we are inside of it and at one time it didn't exist and neither did
we.
Big Bang Theory - The Only Plausible Theory?
Is the standard
Big Bang theory the only model consistent with these evidences? No, it's
just the most popular one. Internationally renown Astrophysicist George
F. R. Ellis explains: "People need to be aware that there is a range of
models that could explain the observations….For instance, I can
construct you a spherically symmetrical universe with Earth at its
center, and you cannot disprove it based on observations….You can only
exclude it on philosophical grounds. In my view there is absolutely
nothing wrong in that. What I want to bring into the open is the fact
that we are using philosophical criteria in choosing our models. A lot
of cosmology tries to hide that."4
