Web(i) The spectrum of black holes states is discrete. The density of states for heavy black holes can be computed up to an (unknown but finite) overall constant. (ii) Baryon number … Web1 day ago · A black hole is one of the simplest objects in the Universe, at least at a macroscopic level, as it is characterized by only three parameters, i.e., its mass, angular momentum, and electric charge.This is guaranteed by the no-hair theorem in general relativity. On the other hand, it is believed that, at a microscopic level, black holes have …

WebProperties of classical black holes and both classical and quantum black hole thermodynamics are treated. The selection and focus is determined by my idiosyncracies, time limitations, and an efiort to illuminate some topics that have not traditionally been emphasized. Vast amounts of interesting and important work on the subject are not … WebJan 20, 2024 · We describe two different, but equivalent semiclassical views of black hole physics in which the equivalence principle and unitarity are both accommodated. In one, unitarity is built-in, while the black hole interior emerges only effectively as a collective phenomenon involving horizon (and possibly other) degrees of freedom.
