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

The Trump administration has proposed closing either the LIGO Hanford observatory in WA or its twin in Louisiana.

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.

A collaboration between humanity’s three gravitational wave detectors have identified a black hole merger event that created ...

Astronomers have detected the signal of a colossal black hole in deep space that likely formed when two already-large black ...

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

The biggest black hole merger yet observed could confirm a rare class of black holes long thought to be missing from the universe.

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