Hawking singularity theorem explained

WebJun 1, 2024 · A singularity is a point in space-time where density, gravity, and space-time curvature are infinite. A black hole singularity is formed when a massive star … WebHowever, Wall has shown that even without energy conditions, the generalized second law implies a quantum singularity theorem [63]. That is, if entropy remains relevant then the singularity theorem holds. If so, some form of cosmic censorship should also persist, and we could use it as a guiding principle to rule out models of Hawking evaporation.
