A Modern Take on the Information Paradox - Lecture 4

Explore recent advancements in addressing Hawking's black hole information paradox in this lecture by Ahmed Almheiri from the Institute for Advanced Study, Princeton. Delve into previous resolution attempts, including concepts of firewalls at the horizon, state dependence of the interior, and ER = EPR. Discover how holography can reproduce the Page curve of an evaporating black hole and examine the first semi-classical model of unitary black hole evaporation. Gain insights into ongoing research deriving these results more generally. Topics covered include quantum states, gravity, HRT prescription, RT formula, bulk entropy, entanglement, semi-classical approximations, and entropy computation.
