Big Bang Theory
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.
