For the first time, physicists have found what they are calling “compelling evidence” for low-frequency gravitational waves, ripples in space-time usually caused by massive cosmic objects orbiting ...

A team of physicists has developed a method to detect gravity waves with such low frequencies that they could unlock the secrets behind the early phases of mergers between supermassive black holes, ...

The recent detection of gravitational waves by the Laser Interferometer Gravitational-Wave Observatory (LIGO) came from two black holes, each about 30 times the mass of our sun, merging into one.

Scientists monitor how ripples in spacetime, most likely caused by the interaction of supermassive black holes, affect the timing of signals from pulsars. (Illustration by Aurore Simonnet for NANOGrav ...
