In 2023, the Laser Interferometer Gravitational-Wave Observatory (LIGO) in the US detected something strange happening in space - the collision of two massive black holes. One black hole was around ...

Scientists say the two black holes merged after colliding at speeds near the limit allowed by Albert Einstein’s theory of ...

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

Astrophysicists have analyzed two merging black holes; the team's best models suggest that at least one, if not both, of the ...

The future of at least one of the U.S. LIGO observatories is in jeopardy as deep cuts to science programs are proposed by the ...

This is the most massive black hole binary we’ve observed through gravitational waves, and it presents a real challenge to ...

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 ...

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

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 massive bill is guided by spending requests from the White House. It will extend the 2017 Trump tax cuts, while cutting ...

A collision observed between two black holes, each more massive than a hundred suns, is the largest merger of its kind ever recorded, according to new research. Gravitational waves were predicted by ...
