Type of Event (for grouping events):

The quest for understanding black holes has been a major driver of new insights inĀ theoretical physics. A major problem that as of yet eludes resolution is Stephen Hawking's information paradox, the claim that information thrown into a black hole is lost forever. This conflicts sharply with the principle of unitarity in quantum physics, and suggests that gravity and quantum mechanics are irreconcilable. However, non-perturbative effects in gravity are believed to be necessary for resolving this problem and for manifesting the quantum nature of black holes. I will discuss how this comes about when studying aspects of an evaporating black hole that gets entangled with its Hawking radiation, including recent results of how this entanglement provides access to the information behind itsĀ event horizon.
