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

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

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 ...

New research suggests that galaxies with quasars at their active hearts are seven times more likely to harbor elusive ...

The gravitational wave background of the universe has been heard for the 1st time. News. ... Supermassive black holes grow surprisingly quickly, study suggests, https: ...

Quasars are supermassive black holes that shoot out giant ... This afterglow is the cosmic microwave background (CMB), leftover radiation from just after the cosmos-birthing explosion that permeates ...

Based on the data, Pardo and Mingarelli predicted that in an optimistic scenario, there are about 112 nearby supermassive black holes emitting gravitational waves. The first detection of the ...

Supermassive black hole found only half a billion years after Big Bang There just isn't time for something that big to grow from a supernova remnant. John Timmer – Nov 6, 2023 5:45 pm | 132 ...

The simulation shows how the black holes distort the starry background and capture light, producing black hole silhouettes. A distinctive feature called a photon ring outlines the black holes. The ...

The physicists suggest, optimistically, over 100 nearby supermassive black holes will be emitting gravitational waves, allowing astronomers to detect the gravitational wave background within the ...

Each black hole’s mass is more than 800 million times that of our sun. As the two gradually draw closer together in a death spiral, they will begin sending gravitational waves rippling through ...

But known particles wouldn't behave quite right under those conditions to form supermassive black holes. So the researchers hypothesized an as-of-yet-unobserved form of matter — ultralight dark ...
