Scientists at the University of Colorado Boulder may have solved a pressing mystery about the universe's gravitational wave ...

Astronomers and astrophysicists at five different pulsar timing array collaborations today announced data that strongly suggests the presence of a gravitational wave background: a constant murmur of ...

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 ...

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 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 ...

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 ...

To understand why scientists are excited about detecting a new background, just look to the history of studies of the CMB. There’s a new cosmological background in town. In June, researchers from the ...
