Gravitational shockwave: LIGO catches a 225-solar-mass black-hole smash-up
2025-07-15
The LIGO-Virgo-KAGRA (LVK) Collaboration has detected the merger of the most massive black holes ever observed with gravitational waves using the US National Science Foundation (NSF)-funded LIGO observatories. The powerful merger produced a final black hole approximately 225 times the mass of our Sun. The signal, designated GW231123, was detectedContinue Reading
