Summary
The black hole is one of the most fascinating and mysterious objects in the universe. Due to its extremely strong gravitational force, nothing that has fallen into it can come back out again. Actually, however, this is the picture in classical theory and, when quantum effects are taken into account, more intriguing phenomena are believed to happen. First, things that have fallen into a black hole can very slowly escape as thermal radiation. Also, a black hole must be made of many underlying microstates and its classical picture is an approximate description obtained by coarse-graining them. To understand the quantum aspects of black holes, we need a quantum theory of gravity, namely string theory. In this talk, I will explain the studies in string theory to elucidate the quantum physics of black holes.
