Theoretical physicists have leapt upon the recent discovery of a background hum of gravitational waves permeating the entire universe, with claims that the signal could be a sign of dark matter or ...
Scientists propose a gravitational-wave method called the stochastic standard siren to measure the Hubble constant, offering an independent way to examine the universe’s expansion and the Hubble ...
Gravitational waves are ripples in the fabric of spacetime predicted by Albert Einstein’s general theory of relativity, first detected in 2015. But an expected corresponding low-frequency ...
When the densest objects in the universe collide and merge, the violence sets off ripples, in the form of gravitational waves ...
The universe is humming with gravitational radiation — a very low-frequency rumble that rhythmically stretches and compresses spacetime and the matter embedded in it. That is the conclusion of several ...
Katie Mack is the Hawking chair in cosmology and science communication at the Perimeter Institute for Theoretical Physics and the author of “The End of Everything (Astrophysically Speaking).” When, ...

Artist’s interpretation of an array of pulsars being affected by gravitational ripples produced by a supermassive black hole binary in a distant galaxy. CREDIT Aurore Simonnet for the NANOGrav ...
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 ...
