For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational ...

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

The team examined the remnant black hole’s “Kerr nature”, the mathematical description of a rotating black hole in general relativity. By analyzing the dominant quadrupolar mode and its overtone, they ...

EVANSTON, Ill. (CBS) -- A Northwestern University astrophysicist is part of an international team of scientists creating a gravitational wave detector system that will eventually be launched into ...

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 ...

University of Colorado Boulder astrophysicist Jeremy Darling is pursuing a new way of measuring the universe's gravitational wave background—the constant flow of waves that churn through the cosmos, ...

A team of physicists has developed a method to detect gravity waves with such low frequencies that they could unlock the secrets behind the early phases of mergers between supermassive black holes, ...

A radical new theory regarding the origin of the universe suggests that gravitational waves, tiny ripples in spacetime first predicted by Albert Einstein back in 1915, could have given rise to cosmic ...

Gravitational wave astronomy is starting to do more than confirm Einstein’s equations. It is turning into a precision tool for mapping the invisible, with theorists now arguing that ripples in ...

Scientists believe that in the very early universe, everything was incredibly tiny, chaotic, and full of random energy ripples, known as quantum foam. It was a state where spacetime was unstable, and ...

The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...
