The 4 laws of black hole mechanics
Web3 Aug 2012 · Quantum mechanics tells us, then, that the reverse reaction B* → A + B can also happen, with an equivalent amplitude. The reverse reaction, though, is one in which the heavier black hole B* spontaneously emits the body A, leaving behind a lighter black hole B. That reverse reaction is exactly what does not happen, according to classical ... Web18 May 2024 · The analogy was completed by extending all four laws of thermodynamics to black holes [3].
