New research with GW230814 upholds Hawking black hole area law
Tokyo, Japan (SPX) Nov 15, 2025
Researchers from Purple Mountain Observatory have conducted an observational test of the black hole area law. Using the gravitational-wave event GW230814, which features a high signal-to-noise ratio, the team closely examined the event horizons of merging black holes. The black hole area law, first proposed by Stephen Hawking in 1971, predicts that the total event horizon area after a merger wil
