## Holography and the Quantum Nature of Black Holes KU Leuven

Some of the most outstanding problems in modern theoretical high energy physics are related to the puzzles arising in the physics of black holes. More than 40 years ago Bekenstein and Hawking discovered that black holes have an entropy proportional to the area of their horizon. A major theoretical challenge is to account for the microstates responsible for this entropy. String theory is a leading theory of quantum gravity that has been used ...
