Hawking's area theorem
WebJul 13, 2024 · Stephen Hawking’s 40-year-old theorem about the area of a black hole’s event horizon has been confirmed thanks to data from the first burst of gravitational waves detected by LIGO. Known as Hawking’s area theorem, it states that the entropy of a black hole should not decrease. Because a black hole’s entropy is proportional to the area ...

WebThe Hawking Area Theorem actually doesn't say anything at all about the black hole losing mass. It's all about the black hole gaining mass. The issue that the theorem was designed to solve, at least according to my own reading of the literature, is that some circumstances that cause a black hole to gain mass, like a collision of two black holes ... WebJul 1, 2024 · Abstract. We present observational confirmation of Hawking’s black-hole area theorem based on data from GW150914, finding agreement with the prediction with 97% (95%) probability when we model the ringdown including (excluding) overtones of the quadrupolar mode. We obtain this result from a new time-domain analysis of the pre- and …

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…
