The Beginning?


Big Bang (Credit:scienceblogs.com)

The universe might have begun with a big bang. Big Bang theory states that our universe came into existence as a singularity and exploded, expanded and cooled off from very small to our current day universe.

What is a singularity? It is thought to be a matter which is squished into a infinitely dense matter by intense gravitational pressure. (Credit:www.big-bang-theory.com)
