As black holes collide across the universe, these waves all hum and resonate together in the background. Gravitational waves travel at the speed of light, but the astronomers realized a single ...

Gravitational waves stretch and squeeze the fabric of space and time itself. When space/time is squeezed, pulsar pulses ...

In comparison, the Laser Interferometer Gravitational-Wave Observatory network can only detect gravitational waves originating from smaller black holes that are up to 10 times as massive as the sun.

Researchers have found the first direct evidence of a “background” of gravitational waves in the universe — a sign that gravitational waves from slowly merging pairs of supermassive black holes, or ...

Supermassive black hum: Scientists discover gravitational wave background that permeates universe The source could be merging black holes — or something more 'mind-bending' ...

Did The universe really begin with a bang, a bounce? The theory that the universe is both possibly having endured a sudden ...

Pinning down the gravitational wave background would clue astrophysicists into the evolution of supermassive black holes; there’s a dearth of intermediate-mass black holes observed in the ...

By pumping background data through a computer, they can produce sound waves. The scientists combed through masses of simulated black hole data until they found the faint but unambiguous sound of ...

Gravitational waves are created by any object that spins, such as the rotating remnants of stellar corpses, orbiting black holes or even two people “doing a do-si-do,” Dr. Mingarelli said.

Based on the analysis so far, the NANOGrav team says the best way to describe the gravitational-wave patterns would be as a background hum — analogous to overlapping voices in a crowd, or the ...
