More than 100 years ago, Albert Einstein proposed something radical in his theory of general relativity: space and time are not fixed backdrops. They bend, stretch and ripple when massive objects move ...

On Earth, a visible ripple effect occurs when a stone is thrown into the water. In space, a similar phenomenon happens. However, instead of creating waves that can be seen by the human eye or optical ...

The Arecibo Observatory in Puerto Rico, one of the radio telescopes used to detect the pulses from pulsars in the new research. The telescope started to fall apart in 2020 and was decommisioned.

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 ...

Astronomers have found a background din of exceptionally long-wavelength gravitational waves pervading the cosmos. The cause? Probably supermassive black hole collisions, but more exotic options can’t ...

In June, scientists presented compelling evidence that they discovered a massive "hum" of low-frequency gravitational waves rippling through the universe. Similar to the ripple effect that occurs when ...
