In a major scientific breakthrough, researchers have detected a persistent gravitational wave background — subtle ripples in ...

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. On September 14, ...

Could it be that the universe’s first structures were born not from enigmatic inflaton fields, but from the echoes of ancient ...

Gravitational wave detectors have "heard" the ripples in space caused by the most massive black hole merger yet. One ...

A collision observed between two black holes, each more massive than a hundred suns, is the largest merger of its kind ever ...

A new method to analyze gravitational-wave data could transform how we study some of the universe's most extreme events—black ...

Scientists have developed a more precise method for analyzing gravitational waves, offering a sharper view into the ...

Gravitational waves are ripples in the space-time continuum first predicted by Albert Einstein 100 years ago. They can be produced in many ways, ...

Gravitational waves, the result of two black holes merging, have been detected by a sophisticated observatory. Scientists say that proves Einstein was right.

The waves in Wednesday's announcement traveled for 1.4 billion years before they reached Earth late last year and set off detectors at the Laser Interferometer Gravitational-wave Observatory (LIGO ...

When scientists at the Laser Interferometer Gravitational-Wave Observatory first realized they had finally detected gravitational waves in September, they kept the discovery largely hidden from ...

The merger resulted in a combined black hole 225 times our sun’s mass, and challenges current astrophysical models of black ...
