Spin fluctuations and black hole singularities: the onset of quantum gravity is spacelike

Abstract: Due to quantum fluctuations, a black hole of mass M represents an average over an ensemble of black hole geometries with angular momentum. This observation is apparently at odds with the fact that the curvature singularity inside a rotating black hole is timelike, while the one inside a non-rotating black hole is spacelike. Is the average of timelike singularities really spacelike? We use the Bekenstein-Hawking entropy formula to introduce a microcanonical ensemble for spin fluctuations and show that the onset… Show more

“…which are in terms of the BH temperature and entropy scaled by the quantities T H, ≡ c 3 /2Gk B M and S H, ≡ 4GM 2 / c. With these thermodynamic relations, we can sample black holes from various underlying distributions. Bianchi et al [17] considered sampling from a microcanonical ensemble, though early-universe fluctuations would arguably draw (M, χ) from a canonical ensemble (i.e. at fixed Figure 8.…”

“…The quantum-mechanical and statistical properties of PBHs may leave imprints on astrophysical observations [16]. Conversely, observations could test whether PBHs were seeded by a quantum thermodynamic process, producing PBHs in a (micro)canonical ensemble [17].…”
