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.

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 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 ...

The curious minds at What If examine overwriting Einstein’s theory of relativity with time travel, imagining paradoxes, causality, and cosmic consequences. Donald Trump approval rating shifts with low ...

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 ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged. This theory tries to ...

The big thinkers at Aperture explain relativity and how it warps the fabric of spacetime. Video shows attack on Ilhan Omar during town hall Trump triggers flight from US dollar Food pyramid faces ...

Time has an arrow: It only ever seems to move in one direction. The future is always unknown to us, while the past forever remains locked and inaccessible. And yet, the vast majority of the laws of ...

CAPE CANAVERAL SPACE FORCE STATION — Despite the number of struggles Relativity Space has faced trying to get the world’s first 3D-printed rocket off the ground, it finally succeeded Wednesday night, ...

Disney's Imagineers checked out "thousands of AI companies" before backing one that keeps animators in the driver's seat. Corinne Reichert (she/her) grew up in Sydney, Australia and moved to ...
