Scientists' recent detection of low-frequency gravitational waves may shed light on what's causing a constant rumble of ripples in the very fabric of space and time. When you purchase through links on ...

Radio telescopes around the world picked up a telltale hum reverberating across the cosmos, most likely from supermassive black holes merging in the early universe. By Katrina Miller Katrina Miller, a ...

LIGO confirmed the existence of gravitational waves in 2015, detecting one-time perturbations of spacetime from the merger of large black holes. There should be a background of gravitational waves ...

You can't see or feel it, but everything around you — including your own body — is slowly shrinking and expanding. It's the weird, spacetime-warping effect of gravitational waves passing through our ...
