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 ...

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 ...

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 ...

A team of international researchers is conducting research to discover the "hum" made by gravitational waves that has never been heard before. Neutron stars cause gravitational waves, and the hunt for ...

In June, scientists presented compelling evidence that they discovered a massive "hum" of low-frequency gravitational waves rippling through the universe. Similar to the ripple effect that occurs when ...

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 ...

Using an array of ticking pulsars stretched across part of the Milky Way, astronomers have found the 'background hum' of gravitational waves that could be the result of merging supermassive black ...

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 ...
