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 ...

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

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 ...

Coalescing supermassive black holes in the centers of merging galaxies fill the universe with low-frequency gravitational waves. Astronomers have been searching for these waves by using large radio ...

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 ...

The results of a comprehensive search for a background of ultra-low frequency gravitational waves has been announced by an international team of astronomers. The results of a comprehensive search for ...

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 ...
