Abstract: Black hole entropy is a robust prediction of quantum gravity with no explored phenomenological consequences to date. In this talk, I discuss how the Bekenstein-Hawking entropy formula allows us to determine the probability distribution of the spin of black holes produced by the collapse of perturbations distributed according to a general relativistic microcanonical ensemble. I will also discuss why this ensemble is relevant for black holes formed in the early universe, resulting in a population of black holes with zero spin. In principle, the identification of such a population at LIGO, Virgo, and future gravitational wave observatories could provide the first observational evidence for the statistical nature of black hole entropy.
