This article is an introduction to causal properties of General Relativity. Topics include the Raychaudhuri equation, singularity theorems of Penrose and Hawking, the black hole area theorem, topological censorship, and the Gao-Wald theorem. The article is based on lectures at the 2018 summer program Prospects in Theoretical Physics that was held at the IAS as well as the New Zealand Mathematical Research Institute summer school held in Nelson in January, 2020.

  1. Geodesic completeness of anisotropic cosmologies and the null energy condition

    gr-qc 2026-08 conditional novelty 7.0 of 10

    A Bianchi-I spacetime obeying the null energy condition and expanding in all directions at one time must have past-incomplete null geodesics.

  2. Boundary imprint of bulk causality

    hep-th 2025-01 conditional novelty 6.0 of 10

    Boundary hyperboloids formed by bulk lightcones satisfy a quadratic tangency condition equivalent to the null geodesic equation of an emergent bulk conformal metric.

  3. Displacement memory and B-memory in generalised Ellis-Bronnikov wormholes

    gr-qc 2025-02 conditional novelty 5.0 of 10

    In a generalized Ellis-Bronnikov wormhole, a gravitational wave pulse leaves lasting changes in geodesic separation and congruence expansion, with the effect size set by the wormhole's throat radius and steepness.
