A Modern Take on the Information Paradox and Progress Towards Its Resolution - Lecture 3

Explore recent advancements in addressing Hawking's black hole information paradox in this 52-minute lecture by Ahmed Almheiri from the Institute for Advanced Study, Princeton. Delve into previous attempts to resolve the paradox, including concepts like firewalls at the horizon, state dependence of the interior, and ER = EPR. Discover how holography can be used to reproduce the Page curve of an evaporating black hole and examine the first model of unitary black hole evaporation that remains semi-classical throughout. Learn about ongoing research deriving these results more generally. Topics covered include quick recap, Bekenstein-Hawking entropy, holographic entropy, semi-classical geometry, quantum external surfaces, and the semi-classical approximation.
