Scientists have used theloudest gravitational wave signal ever recorded to put Albert Einstein’s century-old theory of ...

A record-breaking gravitational wave signal let scientists "listen" to a distant black hole merger and put Einstein's gravity to its toughest test yet.

A new theoretical framework shows how subtle fluctuations in spacetime could be detected using existing interferometers.

Ripples in space-time from a pair of merging black holes have been recorded in unprecedented detail, enabling physicists to test predictions of general relativity ...

(via PBS Space Time) Physicists have long believed that detecting the particle of gravity—the graviton—was fundamentally impossible, with the universe itself seeming to block every direct attempt.

The sharpest black hole collision ever detected just gave Einstein another win—and raised hopes that the next one might rewrite gravity.

A newly detected gravitational wave, GW250114, is giving scientists their clearest look yet at a black hole collision—and a powerful way to test Einstein’s theory of gravity. Its clarity allowed ...

After facing possible steep budget cuts that could have shut down a Louisiana space observatory, scientists are breathing a sigh of relief after recently approved federal science funding exceeded ...

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers ...

A team of researchers led by the University of Warwick has developed the first unified framework for detecting “spacetime fluctuations” - tiny, random distortions in the fabric of spacetime that ...

The Universe is a very violent place, and one truly gets a sense of that when looking at short gamma-ray bursts (GRB). That would be intense and brief explosions in space that last just about two ...
