PHYSICS:
Strings Unknot Problems in Particle Theory, Black Holes
James Glanz
PHILADELPHIA--String theory is going to work. This mathematical structure, based on 10-dimensional "strings" with vibrations and interactions that may describe the structure of our universe at its most fundamental level, has seemed remote from the problems other physicists grapple with. But reports at a meeting here showed that string theory sometimes opens the way to solving seemingly intractable problems in other realms of theory, such as where information is stored inside a black hole.
