Dilaton gravity with a boundary: from unitarity to black hole ...

Webmade Hawking change his mind [9] about the question that information was lost inside a black hole. It is now considered to be a promising candidate for a theory of quantum gravity, where a solution for the black hole information paradox also may be … WebMay 15, 1997 · I discuss features required for preserving unitarity in black hole decay and concepts underlying such a perspective. Unitarity requires that correlations extend on the scale of the horizon. I show, in a toy model inspired by string theories, that such correlations can indeed arise. The model suggests that, after a time of order 4M ln M following the … heseva käpylä

Black hole information, unitarity, and nonlocality - osti.gov

WebDec 1, 2024 · The black hole is tiny, but exerts a colossal gravitational pull, and therefore both the laws of quantum mechanics and the laws of the theory of relativity are relevant to it. ... For a long time, there was an argument in the community on whether black holes violate unitarity, but today, it seems they do not lose information. So quantum ... Webbetween the laws of black hole dynamics, and the standard laws of thermodynamics (see Wald (1994) for a discussion). In particular, it led to the view that the surface gravity is in fact a measure of the black hole’s temperature T = κ 2π, and that the event horizon’s area A is a measure of the black hole’s entropy S = A/4. WebBlack hole complementarity seeks to reconcile three reasonable beliefs: (1) An evap-orating black hole scrambles quantum information without destroying it. (2) A freely falling … heseva koti
