Scientists detect signs of a ‘sea’ of ripples in space-time – Business Insider – Business Insider
Supermassive black holes merging in distant galaxies could be creating a background hum of gravitational waves, which were first proposed by Einstein.

Scientists may be on the brink of discovering a new phenomenon reverberating throughout the cosmos: a steady thrum of ripples in space-time.
Albert Einstein first predicted that colliding massive objects like black holes would create such ripples, called gravitational waves. But he thought that the noise and vibrations on Earth would prevent us from ever being able to detect these waves. In that aspect, Einstein was wrong. One of the most remarkable experiments in history — the Laser Interferometer…
