Physics Gravitational waves produce a background hum across the whole universe. After decades of searching, astronomers have found a distinctive pattern of light, from spinning stars called ...

A 15-year search reveals the first evidence of a cosmic 'gravitational wave background' emitted by ancient, colliding black holes. When you purchase through links on our site, we may earn an ...

Such waves cause the 4-km perpendicular arms of the interferometers to change length by miniscule (but different) amounts, the difference detected by changes in the resulting interference pattern ...

The idea was that the gravitational wave background is uniform; there are supermassive black holes merging in so many different directions and distances that overall, they make up a consistent ...

Cosmic lighthouses as gravitational wave detectors . To detect the gravitational wave background, astronomers studied fast-spinning stars called millisecond pulsars, which are dead stars that spin ...

A 15-year study has revealed the cosmic background noise of gravitational waves echoing across the universe for the first time.

The claim of a gravitational wave background suggests the universe is constantly roiled by violent events that happened over the past 13 billion years. Accessibility statement Skip to main content.
