Black hole thermodynamics - Wikipedia

The Penrose–Hawking singularity theorems (after Roger Penrose and Stephen Hawking) are a set of results in general relativity that attempt to answer the question of when gravitation produces singularities. The Penrose singularity theorem is a theorem in semi-Riemannian geometry and its general relativistic interpretation predicts a gravitational singularity in black hole formation. The Hawking singularity theorem is based on the Penrose theorem and it is interpreted as a gravitati… WebNo-hair theorems: a black hole is fully-described by just a few numbers (mass, spin etc) irrespective of the type or configuration of the matter/energy within the event horizon. Surface area measures entropy: you can't reduce the total entropy of the universe by throwing a box of hot gas into a black hole, its size/entropy will increase by the ... bjorn women\u0027s boots

WebHawking's area theorem is a fundamental result in black hole theory that is universally associated with the null energy condition. That this condition can be weakened is … WebApr 27, 2024 · The area theorem has been experimentally verified, and, we do know that Hawking radiation originates from outside the event horizon, taking energy from the black hole's gravitational field (which we know extends outside the EH), and this could make one think that the energy content "inside" the event horizon does not decrease, leading to the ...
