Well, I don't really expect people to watch this, as it's a 10 minute clip, but this is an *intro* to M-Theory, a controversial subject in quantum physics. It hasn't been proven yet, but that's what they're trying to do with the Large Hadron Collider -- they will be able to create a universe in a laboratory, essentially.

This video is a very rough intro, and doesn't explain everything clearly, because it is a complicated subject and I don't feel that I could condense into a short forum post, myself. The show, itself, is very interesting though and I highly recommend looking it up if you find the topics in the short video interesting.
M-Theory attempts to explain what happened before, during, and after the Big Bang.
I'm not trying to convince anybody. I just think it's interesting. I really don't think non-believers and believers can change one anothers minds.
