A new theoretical study suggests that gravitational waves may leave subtle signatures not in giant detectors, but in the light emitted by atoms.

Gravitational waves are usually hunted by measuring distance—how space itself stretches and shrinks ever ...

A soaring cosmic symphony surrounds us; its notes emerge from massive celestial objects crashing together hundreds of millions or even billions of light-years away. Ever since astronomers announced ...

This week, among a lot of other important findings, we learned that emperor cichlid fish have gaze sensitivity and dislike it ...

A faint hum of gravitational waves rippling across the cosmos is now telling scientists what no telescope could show them: the dense, hidden structures buried at the centers of galaxies. A team of ...

After a three-year hiatus, scientists in the U.S. have just turned on detectors capable of measuring gravitational waves—tiny ripples in space itself that travel through the universe. Unlike light ...

You can't see or feel it, but everything around you — including your own body — is slowly shrinking and expanding. It's the weird, spacetime-warping effect of gravitational waves passing through our ...

One of the most spectacular achievements in physics so far this century has been the observation of gravitational waves, ripples in space-time that result from masses accelerating in space. So far, ...

There’s a monster lurking at the center of every galaxy, millions of miles wide and millions of times more massive than our Sun: a supermassive black hole. When two of these cosmic leviathans meet, ...

The newly detected gravitational wave background could be the result of supermassive black hole binaries that orbit each other for a few million years before merging. By now you’ll have seen the news ...

Until recently, gravitational waves could have been a figment of Einstein’s imagination. Before they were detected, these ripples in spacetime existed only in the physicist’s general theory of ...
