For anyone in the Windy City in November, there's a lecture at the Fermilab on Friday November 13 entitled "The Sounds of Spacetime: Black Holes, Early Universe, Cosmic Strings, and Holographic Noise" by Dr. Craig Hogan. He's one of the guys at the forefront of research into the possibility that the universe is a holographic projection of three dimensions onto the two dimensional membrane that is the boundary of space-time.

This falls out of Hawkins and Gerard 't Hooft's and others theories that a black hole encodes in its membrane all the information that it has swallowed because if it didn't it could break the 2nd law of thermodynamics by reducing entropy.

Sounds groovy to me.

Some of Hogan's previous talks are available here.
