The Impact of the Chrono-geometrical Structure of Spacetime on Causality

Abstract

We discuss the usual account of causal structure that relies on the temporal precedence constraint between cause-effect pairs. In particular, we consider the subtle interplay between local and global characters of time and causality encoded in General Relativity. We find that the temporal precedence constraint must be relaxed. We argue that these results could lead to an enriched structure of the physical causality.Comment: 13 pages, accepted by the Revue des Questions Scientifique
