Physicists with the LIGO/Virgo/KAGRA collaboration have detected the gravitational wave signal (dubbed GW231123) of the most massive merger between two black holes yet observed, resulting in a new ...

Two colossal black holes among the most massive ever seen collided in deep space, creating gravitational waves that rippled across the cosmos and shook the foundations of astrophysical theory.

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 ...

Scientists detected the merger of two extremely massive black holes. This merger created the most massive black hole ever observed through gravitational waves. The black holes' size and rapid spin ...

Talk about epic. A collision of two black holes is so extreme that it’s challenging physics theories of how large black holes form and merge. The two black holes had masses bigger than any before ...

Sept. 14, 2015, was one of the most important days in science history. It marked the first-ever detection of gravitational waves, tiny ripples in space-time (the four-dimensional union of space and ...

LIGO Hanford detected record-setting black hole merger, challenging current knowledge. Merged black holes spun near general relativity’s limit, baffling scientists. Funding cuts threaten U.S.

Senate bill includes funding to keep both U.S. LIGO observatories operational. LIGO confirmed 300 gravitational wave events since Nobel-honored 2015 discovery. Sen. Murray worked to save LIGO by ...
