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

A gravitational wave has revealed the biggest black-hole merger ever recorded—so massive and extreme, it defies current astrophysical models. The clash formed a 225-solar-mass monster, possibly made ...

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

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

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

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

A puzzling gravitational wave was detected, and astronomers have determined that it comes from a record-breaking black hole ...

The Trump administration has called for shutting down either a Tri-Cities, WA, or Louisiana observatory that work in tandem.

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

A collision observed between two black holes, each more massive than a hundred suns, is the largest merger of its kind ever ...

Gravitational wave detectors have "heard" the ripples in space caused by the most massive black hole merger yet. One ...

And LIGO’s second gravitational wave event, GW151226, is great for both! Essentially, on the pessimist’s side, GW151226 makes it all-but-certain that LIGO is picking up genuine gravitational ...
