The merger wasn’t just the biggest ever, but also an event so rare that it challenges existing models for black hole genesis.

The LIGO-Virgo-KAGRA (LVK) collaboration has announced a groundbreaking discovery in the field of gravitational wave ...

The largest black hole collision ever recorded has scientists' jaws on the floor — and scratching their heads.

Physicists call such ripples gravitational waves. Gravitational waves were predicted by Albert Einstein in 1915 as part of his theory of relativity, but he thought they were too weak to ever ...

Gravitational-wave detectors have captured their biggest spectacle yet: two gargantuan, rapidly spinning black holes likely ...

Learn more about LIGO, the observatory that detected two massive black holes merging, the largest in recorded history.

Astronomers have detected the largest black hole merger ever, and it has challenged their understanding of such formations.

The massive black hole has been dubbed GW231123. Its unusual size and behavior is challenging scientists' understanding of ...

A U.S. gravitational wave detector spotted a collision between fast-spinning “forbidden” black holes that challenge physics ...

The LIGO Hanford Observatory near the Tri-Cities and its twin in Louisiana detected ripples of time and space passing through ...

The powerful merger, designated GW231123, produced an extremely large black hole about 225 times the mass of our Sun.
