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 ...

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 ...

Researchers just announced the discovery of the gravitational wave background. After a 15-year-long study, the scientists have finally “heard” what they were looking for: the gravitational waves that ...

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 ...

According to the general theory of relativity, gravitational waves are produced by accelerating mass distributions with a quadrupole (or higher) moment. Moreover, in the early phases of the evolution ...

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 ...
