A Modern Take on the Information Paradox - Lecture 2

Explore a comprehensive lecture on the modern approach to the black hole information paradox and recent progress towards its resolution. Delve into previous attempts to solve this 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 semi-classical model of unitary black hole evaporation. Cover topics such as the Page curve, Hayden-Preskill protocol, random tensors, cloning paradox, black hole complementarity, and the firewall paradox. Gain insights into the application of strong subadditivity of entropy and the ER=EPR conjecture in addressing this fundamental problem in theoretical physics.
