Scientists monitor how ripples in spacetime, most likely caused by the interaction of supermassive black holes, affect the timing of signals from pulsars. (Illustration by Aurore Simonnet for NANOGrav ...

The fabric of the universe is constantly rippling, according to astronomers who have discovered a background buzz of gravitational waves. These waves may be produced by supermassive black holes ...

On Earth, a visible ripple effect occurs when a stone is thrown into the water. In space, a similar phenomenon happens. However, instead of creating waves that can be seen by the human eye or optical ...

Astronomers say they have found the first evidence of a long-theorised form of gravitational waves that create a “background hum” rumbling throughout the universe. The findings, unveiled on Wednesday, ...

In the last decade, astronomers made a major discovery, confirming the existence of gravitational waves. These long-theorized ripples in spacetime are created when extremely massive bodies such as two ...

The waves stretch and compress space-time itself as they travel through the universe An artistic interpretation of an array of pulsars being affected by gravitational ripples produced by a ...

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 Earth’s hum comes from the bottom of the sea and not from turbulence in the atmosphere, says a US researcher, backing a novel theory put forward in 2004. The hum is a low rumble continually ...

WASHINGTON, June 28 (Reuters) - Scientists on Wednesday unveiled evidence that gravitational waves, the ripples in the fabric of space-time predicted by Albert Einstein more than a century ago, are ...
