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

At 225 solar masses, this gargantuan merger of two black holes challenges our thinking on these famously elusive objects.

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

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

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

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

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 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.

A short-lived ripple in space-time revealed that two black holes merged into a giant black hole with the mass of 225 suns ...

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