Time and the big bang
Speaker(s): Neil Turok
Abstract: The evidence for the big bang is now overwhelming. However, the basic question of what caused the bang remains open. One possibility is that time somehow 'emerged,' placing the universe in an inflationary state. Another, perhaps more conservative possibility, is that the big bang was a violent event in a pre-existing universe. I will describe model calculations employing the AdS/CFT correspondence which show how this is possible, and which point to a new explanation for the origin of large scale structure in the universe.
