Where Does General Relativity Break Down?

Abstract

It is widely accepted by physicists and philosophers of physics alike that there are certain contexts in which general relativity will break down. In such cases, one expects to need some as-yet-undiscovered successor theory. This article discusses certain pathologies of general relativity that might be taken to signal that the theory is breaking down and considers how one might expect a successor theory to do better. The upshot is an unconventional interpretation of the strong cosmic censorship hypothesis.
