Quantum Black Holes Are Tied to D-Branes and Strings
Graham P. Collins · Physics Today · 1997
General relativity and quantum mechanics, two of the monumental achievements of 20th-century physics, verified by experiment to unprecedented levels of accuracy, have long resisted physicists' attempts to combine them in a single comprehensive theory. In recent years much research in this area has focused on one central conundrum: how to describe the quantum physics of black holes.
