Since the gravitational waves predicted by Einstein were first detected in 2015, astrophysicists have been pondering the gravitational wave background—the cumulative undulations of these spacetime ripples as they cross the cosmos.
Researchers detected ripples in spacetime using data from the Fermi Gamma-ray Space Telescope to measure small changes in time it took photons to travel from distant pulsars.
Scientists detect resonant hum’ permeating the universe from gravitational wave data
Study authors suspect the low-frequency signal might be coming from gravitational waves, which serves an indicator of cosmic activity.

Scientists may have, for the first time, heard the gravitational wave background or resonant hum that permeates the Universe for the very first time. North American Nanohertz Observatory for Gravitational Waves (NANOGrav) detected the sound. The findings from the observations were published in the
Astrophysical Journal Letters. In the research, scientists analysed data over a span of 13 years. Researchers studying the signals from distant pulsars, made use of radio telescopes to collect statistics that may indicate the effects of gravitational waves.
When supermassive black holes merge, they create a low thrum of gravitational waves that permeates the universe, and we may have just spotted it for the first time
