Talk: Geodesic causality in Kerr spacetimes, Nov 20, 2024
Abstract
Kerr spacetimes are solutions of vacuum Einstein field equations and model the gravitational field around rotating black holes. The natural analytic extension of the Kerr spacetime over the horizons and in the negative radial region, called Kerr star, contains closed causal curves. Despite causality violations, I will sketch the proof of the nonexistence of closed null geodesics in the Kerr-star spacetime.
