Cosmic Censorship: the Role of Quantum Physics
Shahar Hod
Abstract
The cosmic censorship hypothesis introduced by Penrose thirty years ago is still one of the most important open questions in classical general relativity. The main goal of this paper is to put forward the idea that cosmic censorship is intrinsically a quantum phenomena. We construct a gedanken experiment which seems to violate the cosmic censorship principle within the purely classical framework of general relativity. We prove, however, that quantum physics restores the validity of the conjecture. It is therefore suggested that cosmic censorship might be enforced by a quantum theory of gravity.
