Horizons and Apocalypses
Abstract: After reviewing some simple facts in Kinematics of point particles in General Relativity, we present a recent theorem on light-like hypersurfaces in Lorentzian manifolds. It is a result which yields a simple way to determine boundaries of black holes (usually called ``event horizons'') and of regions with time confinements (we call them ``apocalypses''). The talk is designed for a geometry-oriented audience, with no need of a deep prior knowledge in General Relativity.
