I had the pleasure of attending a lecture given by Paul Steinhardt, a Princeton professor, regarding the big bang and cyclic universe models at Fermilab this evening. Steinhardt, having written a book called The Endless Universe, is obviously a fan of the cyclic universe camp and the main focus of the talk was to introduce this as a legitimate alternative. Both theories were discussed in the framework of string theory, particularly brane theory, and it was interesting to see how these different approaches to looking at the universe relate to the theory. Now, not being very much in the cosmological community, I had not realized that this was such a viable alternative to traditional inflationary big bang models. So, I would like to open the discussion up as to which you believe to be correct, why, and any current evidence which points towards one or the other.
