"Spacetime Foam, Black Holes, and Computation"

Jack Ng
University of North Carolina

Spacetime is composed of a fluctuating arrangement of bubbles or loops called spacetime foam. We show that vibrations produced by the foam are almost within range of detection with modern laser-based interferometers. Our spacetime foam picture is consistent with Hawking's estimate of black hole lifetime and the theoretical bound on the amount of information that can be stored in a spatial region. We also show that clock precision and bounds on computation are related to the inextricably-linked spacetime foam and black hole physics. (The talk will start with a short tutorial on quantum mechanics and general relativity, to make it understable to a mixed audience.)
