Hawking area theorem
WebHawking's area theorem applies with a positive energy condition. Hawking radiation creates a negative energy condition. Without the black hole absorbing additional mass the energy condition is negative due to the Hawking radiation, Hawking's area theorem doesn't apply, and the black hole evaporates. 459 level 2 Drachefly · 3m · edited 3m WebJul 7, 2024 · If Hawking’s area theorem holds, then the horizon area of the new black hole should not be smaller than the total horizon area of its parent black holes.

WebBlack holes in general relativity are commonly believed to evolve towards a Schwarzschild state as they gradually lose angular momentum and electrical charge under Hawking evaporation. However, when Kim and Wen applied quantum information theory to WebJul 14, 2024 · Given high enough densities, Einstein’s theory of general relativity predicts that matter can suffer a cataclysmic collapse to a point-like region where both the density of matter and the curvature of space-time diverge (tend towards infinite values). This is referred to as a singularity, and also describes the formation of a black hole.
Webare used in a study of the violation of the area entropy law for free fermions in [18]. This work also provides evidence towards a conjecture due to Harold Widom. 1. Introduction ... related to various versions of the strong Szego¨ limit theorem (SSLT) for dimension one [22] and also for the higher dimensional case [18], see Remark 2.4 below. ... The four laws of black hole mechanics are physical properties that black holes are believed to satisfy. The laws, analogous to the laws of thermodynamics, were discovered by Jacob Bekenstein, Brandon Carter, and James Bardeen. Further considerations were made by Stephen Hawking. The laws of black hole mechanics are expressed in geometrized units. The horizon has constant surface gravity for a stationary black hole.
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…
