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 ...

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

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.

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

An international team of physicists discovered the largest-ever merger of 2 black holes through a phenomenon known as gravitational waves.

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

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

“It’s the most massive [merger] so far,” says Mark Hannam, a physicist at Cardiff University, UK, and part of the LVK ...

The Laser Interferometer Gravitational-wave Observatory (LIGO) is no stranger to making history and breaking records. In 2015 ...
