WebOct 29, 2024 · The black hole was not a big black ball but a short line segment. Still, the researchers argued, gravity is gravity, and what goes for this impoverished Lineland should hold for the real universe.

WebJul 7, 2024 · Just saw a documentary about resolving Hawking's "information paradox". In my own lay terms the physicists appear to theorize resolving the paradox with with their proposed C = 12 J . C is the central charge (which I don't fully understand) and J is the total angular momentum of the black hole. 12 is an interesting and elegant coefficient (IMHO ... WebApr 11, 2024 · The Black Hole Formula for the Entropy. It is reasonable to suppose that the entropy of a black hole should depend only on one or more of the three observable quantities, M, Q and J. According to the area theorem, the area of the event horizon of a black hole cannot decrease. This reminds us of the behavior of the ordinary …
