Gravitational-wave detectors have captured their biggest spectacle yet: two gargantuan, rapidly spinning black holes likely forged by earlier smash-ups fused into a 225-solar-mass titan, GW231123. The ...

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-funded (NSF) LIGO ...

Fuzziness may rule the quantum realm, but it can be manipulated to our advantage. When two black holes spiral inward and collide, they shake the very fabric of space, producing ripples in space-time ...
