Determinism and General Relativity

We investigate the fate of determinism in general relativity (GR), comparing philosopher’s account with physicist’s well-posed initial value formulations. The is interwoven question what it for a spacetime to be ‘physically reasonable’. A central concern status global hyperbolicity, putatively necessary condition GR. While hyperbolicity may fail true all physically reasonable models, we analyze whether should (i) imposed by fiat; (ii) established from weaker assumptions, as cosmic censorship theorems; or (iii) justified beyond-GR physics.
