Gravitational Radiation from the Early Universe

Craig Hogan (University of Washington)

Sometime during the next ten years, gravitational waves will likely be detected for the first time. The dominant radiation will probably come from extremely energetic sources in the present day universe, but there may also be a detectable stochastic background left over from the very early universe that informs us of early events about which we have no other information. The talk will discuss the techniques of detecting stochastic backgrounds, and the physics of their production-- for example, the formation of our three-dimensional space out of a larger fundamental space of more dimensions.
