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 ...

Gravitationally speaking, the universe is a noisy place. A hodgepodge of gravitational waves from unknown sources streams unpredictably around space, including possibly from the early universe.

Researchers have found the first direct evidence of a “background” of gravitational waves in the universe — a sign that gravitational waves from slowly merging pairs of supermassive black holes, or ...

There's a galaxy-spanning gravitational wave detector that has provided a breakthrough. It was pretty impressive when LIGO detected gravitational waves from colliding black holes. Well, we’ve just ...

Gravitational waves are ripples in the fabric of spacetime predicted by Albert Einstein’s general theory of relativity, first detected in 2015. But an expected corresponding low-frequency ...

The universe is a turbulent place. Stars are exploding, neutron stars collide, and supermassive black holes are merging. All of these things and many more create gravitational waves. As a result, the ...

The universe is humming with gravitational radiation — a very low-frequency rumble that rhythmically stretches and compresses spacetime and the matter embedded in it. That is the conclusion of several ...

Physicists announced late Wednesday (June 28, 2023) that they’ve discovered the first compelling evidence for the elusive gravitational wave background. If they’re correct, they’ve proved Einstein ...

Assuming LIGO’s recently detected black hole merger is not unusual, researchers revised upward their estimate of the strength of the background noise coming from distant mergers across the Universe.

Cosmic claims: researchers have used radio telescopes around the world to hunt for gravitational waves using the subtle variations in the timing of pulsars. (Courtesy: Aurore Simonnet for the NANOGrav ...
