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 ...

Astronomers just discovered a background “hum” of low-frequency gravitational waves constantly rippling through the universe — but what’s next? When two galaxies merge, the supermassive black holes at ...

The gravitational waves we’ve detected so far have been like tsunamis in the spacetime sea, but it’s believed that gentle ripples should also pervade the universe. Now, a 13-year survey of light from ...

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 ...

Things are about to change in a supermassive way in the world of astrophysics. An international team of scientists have discovered evidence for a new type of signal they have long searched for—one ...

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 ...
