The Big Bang Theory of the origin of the universe is pretty much set in stone - or so you would think. Turns out there are several problems with the Big Bang model, some of which are answered with Inflation Theory; the idea that in the first trillionth of a second the universe expanded from a singularity to something the size of a basketball, then slowed its expansion.

But there is another idea, one based on string theory and gives the possibility for the universe to renew itself over and over again in cycles. It's called the Ekpyrotic Universe Theory. And it's weird. Real weird.
