Talk title: Gravity insights from replica wormholes

Abstract:

Black holes have long been a source of theoretical tension between general relativity and quantum mechanics. Recent light has been shed on these problems by a new gravitational formula for entropy, and its application to compute the information content of a black hole and its Hawking radiation. This formula is underpinned by “replica wormholes”, a non-perturbative effect in the low-energy effective theory of quantum general relativity. The insights from this and similar results suggest a new paradigm for interpreting the effective theory of quantum gravity.
