The Big Bounce

[andywood]

Last year I remember reading an article in Scientific American about a Big Bang alternative theory called the Big Bounce. It basically states that instead of a definite begining or end, the universe is actually eternally exploding then imploding back in on itself and then exploding outward again. I dont remember much else besides that from the article other than it worked because of some strange quantum physics that I was really confused by it. Does anyone know what I'm talking about and can expalin how it works for me?

The links on this site do a FINE job, and are rather accessible even if you haven't formally studied the topic:

Reviewing those for a little while would probably get you farther than any short answer I could offer.

I think that the OP means Loop Quantum Cosmology:

I believe that Martin is a real fan of this, so I will defer to his expertise.

Indeed. There are a couple of links on Cosmology and quantum gravity in the URL I shared (which, funny enough, I got from Martin )

Cool, that's a really interesting site. I think I kind of understand it, at least for a non-physicist-ish-type-person to get the main gist of the theory and how it works. Thanks!
