Ripples in spacetime now give astronomy a second sense. The network listens to collisions, maps a low-frequency background ...

Ten years ago, scientists heard the universe rumble for the first time. That first discovery of gravitational waves proved a ...

For the past decade, gravitational wave astronomy has opened our eyes to amazing cosmic phenomena thanks to LIGO, the Laser ...

A decade after the first discovery, scientists have used these waves to find a unique merger, a massive binary system and a ...

Gravity has shaped our cosmos. Its attractive influence turned tiny differences in the amount of matter present in the early universe into the sprawling strands of galaxies we see today. A new study ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

"GW250114 is the loudest gravitational wave event we have detected to date; it was like a whisper becoming a shout." ...

General relativity has passed one of its most precise tests ever thanks to observations of the past 11 billion years of cosmic evolution collected by the Dark Energy Spectroscopic Instrument, or DESI.

Earth and the Moon are forever locked in a gravitational embrace that has played a critical role in determining the fate of both worlds. Although they have grown more distant since their formative ...
