Gravitationally speaking, the universe is a noisy place. A hodgepodge of gravitational waves from unknown sources streams unpredictably around space, including possibly from the early universe.

There's a galaxy-spanning gravitational wave detector that has provided a breakthrough. It was pretty impressive when LIGO detected gravitational waves from colliding black holes. Well, we’ve just ...

On June 29, five independent teams of radio astronomers published a series of papers presenting evidence that the universe is filled with gravitational waves created by colliding supermassive black ...

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 ...

Cosmic claims: researchers have used radio telescopes around the world to hunt for gravitational waves using the subtle variations in the timing of pulsars. (Courtesy: Aurore Simonnet for the NANOGrav ...
