Jun 18, 2021 · A study based on the first-ever detection of gravitational waves from two merging black holes shows that their surface area increased, as predicted by Hawking's theorem. The result implies a link between black hole entropy and the second law of thermodynamics, but also challenges Hawking's radiation theory.

Jul 1, 2021 · Physicists at MIT and elsewhere have used LIGO data to observe the area law of black holes for the first time. The study shows that the area of a black hole’s event horizon can never decrease, a result derived by Stephen Hawking in 1971.
Jul 7, 2021 · Physicists at Cornell, MIT and elsewhere have tested Hawking’s area theorem, which predicts that the total area of black hole event horizons should never decrease, using observations of gravitational waves from a binary black hole merger. They found that the final black hole had a larger area than the sum of its parents, supporting Einstein’s theory of relativity.
Physicists at Cornell, MIT and elsewhere have tested Hawking’s area theorem, which predicts that the total area of black hole event horizons should never shrink, using observations of GW150914, the first gravitational wave signal detected by LIGO. They found that the area law holds with 95 percent confidence and that black holes behave as thermal objects.
Mar 14, 2024 · How does quantum physics explain the radiation of black holes? Fifty years after Hawking's seminal paper, physicists are still puzzled by the fate of information swallowed by black holes.

Jun 3, 2024 · Stephen Hawking suggested black holes "leak " and evaporate away — scientists could use "morsels" launched from catastrophic black hole collisions to prove it.
Apr 5, 2024 · Physicists have found a way to explain how black holes have entropy, or disorder, based on quantum effects. This solves a long-standing problem that Stephen Hawking and Jacob Bekenstein faced in the 1970s.
