Lecture:- Replica Wormholes and the Black Hole Interior
In 1970s, Stephen Hawking raised a tension between general relativity and quantum mechanics in the black hole background: the famous black hole information paradox. During the past half-century, the black hole information paradox has been one of the biggest puzzles in theoretical physics and various efforts has been made to sharpen the information paradox. The most quantitative formulation of the information paradox concerns about the behavior of the entropy of the hawking radiation. From Hawking’s calculation, the entropy of hawking radiation keeps growing with time, while for a unitary system, the entropy should eventually vanish as argued by Don Page. In this talk, the speaker will argue that a key ingredient called the replica wormhole, which was missed in Hawking’s original calculation, solves the entropy puzzle and leads to a unitary evolution. Based on work with Geoff Penington, Stephen Shenker and Douglas Stanford.
