Black hole singularity theory

WebMar 18, 2024 · Physicists have cleverly dodged this issue by inventing their own singularity-free black holes, which they call “dark stars”. These imaginative creations … WebThe evolution of Kerr black holes under Hawking evaporation is straightforward – they spin down. It is true that if a Kerr black hole only emits scalar particles, it will evolve towards a/M ≈ 0.555, however once higher spin particles are added, the final state would be a/M → 0 [31, 32]; see also [33].
