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

At 225 solar masses, this gargantuan merger of two black holes challenges our thinking on these famously elusive objects.

An international team of physicists discovered the largest-ever merger of 2 black holes through a phenomenon known as ...

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

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

Scientists are using pulsars to detect the gravitational wave 'hum' created from supermassive black hole mergers. Credit: ...

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

A new theory promises to simplify our approach to the universe's earliest moments, but some cosmologists say further ...

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

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 ...

Since a gravitational wave is a propagating change in gravity, there will be very small fluctuations in the speed of time, but since gravitational waves are inherently weak, ...
