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