Illustration of two black holes orbiting each other. Initially, scientists expected LIGO might detect just a few of these collisions. But now, nearing the first detection’s 10th anniversary, we have ...

LISA Pathfinder has produced astonishingly accurate results, paving the way for revealing the secrets of the universe with all-new insight into gravity. Share on Facebook (opens in a new window) Share ...

Gravitational-wave detectors have captured their biggest spectacle yet: two gargantuan, rapidly spinning black holes likely forged by earlier smash-ups fused into a 225-solar-mass titan, GW231123. The ...

Long ago, in a galaxy far away, two black holes danced around each other, drawing ever closer until they ended in a cosmic collision that sent ripples through the fabric of spacetime. These ...

Using gravitational waves, tiny ripples in space-time first predicted by Albert Einstein back in 1915, astronomers have discovered that a "stellar graveyard" is packed with mergers between extreme ...

Researchers have designed a new type of gravitational wave detector that operates in the milli-Hertz range, a region untouched by current observatories. Built with optical resonators and atomic clocks ...

Sept. 14, 2015, was one of the most important days in science history. It marked the first-ever detection of gravitational waves, tiny ripples in space-time (the four-dimensional union of space and ...

A new effort to map the rumblings in spacetime caused by enormous black hole collisions paints a surprisingly loud and lopsided picture of the universe. When you purchase through links on our site, we ...

Einstein's theory of general relativity suggests that the "memory" of ancient events, such as black hole mergers, may be etched into the fabric of space-time by gravitational waves. New research shows ...
