Astronomers announced on September 17, 2025, the detection of a black hole merger that provides strong evidence for Stephen Hawking's area theorem. Observed via gravitational waves, the event aligns with predictions that black hole surface areas cannot decrease. This bolsters fundamental physics theories amid ongoing cosmic explorations.

Astronomers detected the strongest black hole collision yet on September 11, 2025, resonating with Einstein's predictions. The event involved massive black holes merging, producing significant gravitational waves. This finding was published in a leading science journal, advancing astrophysics.
