Stephen Hawking is speaking tonight at Caltech and i can't go--im relegated to bed, trying to make a hasty recovery. Ugh.
Absent from this (undoubtedly) great talk where probably the most interesting questions are being answered, the most fascinating theories are being expounded, and the most yummee coffee in the world is being brewed in those tall silver coffee jugs at the Beckman Center (have i idealized the situation enough?), i speculate what Stephen might be saying about black holes:
Are they really black? I give in, Susskind is right....stuff might come out of them. Can black holes be pathways into other universes?
If i had been witness to this fun speculation, i would have asked, How does string theory explain or relate to black holes? (Hmph)
According to superstringtheory.com...
A special type of black hole that is very important in string theory is called a BPS black hole. A BPS black hole has both charge (electric and/or magnetic) and mass, and the mass and the charges satisfy an equality that leads to unbroken supersymmetry in the spacetime near the black hole. This supersymmetry is very important because it results in the disappearance of messy quantum corrections, so that precise answers about the physics near the black hole horizon can be found by simple calculations. Since a point can be thought of as a zero-brane, a natural generalization of a black hole is a black p-brane. And there are also BPS black p-branes.
This was the
basic answer as to how black holes relate to string theory--WHAT?!
Until i can get around to reading
Black Holes and Timewarps, i'll have to settle for picturing it like a Richard Deacon sculpture.

Casey, I Love Your Blog. Its well-written, thought provoking and beautiful to look at. Its inspiring me to be more consistent in the upkeep of mine (which currently has one sad little post).
