Title:
“Holography abhors visible trapped surfaces”
Abstract:
One of the main consequences of the weak cosmic censorship conjecture is that trapped surfaces are hidden by event horizons. We prove that the holographic dictionary implies this result. In particular, we show that the existence of a trapped surface implies the existence of an event horizon, and that this event horizon must be outside of the trapped surface. We make few assumptions beyond the absence of evaporating singularities in the strictly classical gravity limit: thus our result provides a holographic derivation of a hallmark consequence of the longstanding weak cosmic censorship conjecture. We discuss the possibility that a classical gravity theory that admits AdS solutions with trapped surfaces outside of a horizon is not holographic and possibly has no consistent UV completion. We comment on a connection to chaos and holographic complexity.
