The MPTA is sensitive to gravitational waves with wavelengths more than a billion times longer than those of terrestrial gravitational wave detectors such as LIGO or VIRGO. It searches for …
Found! Long-sought gravitational wave background - EarthSky
在earthsky.org上查看更多信息Physicists announced late Wednesday (June 28, 2023) that they’ve discovered the first compelling evidence for the elusive gravitational wave background. If they’re correct, they’ve proved Einstein right yet again, demonstrating that the motion of massive objects twists and distorts both time and space, ringing the universe like …The universe is vibrating, mounting evidence shows

Gravitational wave background - Wikipedia
The gravitational wave background (also GWB and stochastic background) is a random background of gravitational waves permeating the Universe, which is detectable by gravitational-wave experiments, like pulsar timing arrays. The signal may be intrinsically random, like from stochastic processes in the early Universe, or may be produced by an incoherent superposition of a large numb…
