Scientists may have identified the gravitational waves that make up some of the universe’s background, not just those coming from unusual events like black hole collisions. New Atlas reports that the ...

“To tease out the gravitational-wave background, we had to nail down a multitude of confusing effects, such as the motion of the pulsars, the perturbations due to the free electrons in our galaxy, the ...

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 ...

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 ...

General relativity is one of the most successful theories mankind has ever developed, but one of its predictions—the existence of gravity waves—has never been confirmed. Gravity waves are analogous to ...

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 ...
