The newly detected gravitational wave background could be the result of supermassive black hole binaries that orbit each other for a few million years before merging. By now you’ll have seen the news ...

On Earth, a visible ripple effect occurs when a stone is thrown into the water. In space, a similar phenomenon happens. However, instead of creating waves that can be seen by the human eye or optical ...

Astronomers and astrophysicists at five different pulsar timing array collaborations today announced data that strongly suggests the presence of a gravitational wave background: a constant murmur of ...

Astronomers may be getting closer to discovering as-yet hidden cosmic secrets, such as the nature of dark matter and the presence of widespread distortions in space-time, researchers reported at the ...

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 ...

A new type of gravitational wave detector running in Western Australia has recorded two rare events that might be signals of dark matter or primordial black holes. These high-frequency gravitational ...

Scientists' recent detection of low-frequency gravitational waves may shed light on what's causing a constant rumble of ripples in the very fabric of space and time. When you purchase through links on ...

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 black holes need a place to crash, they prefer a nice, bright quasar. So says Chiara Mingarelli, an assistant professor of physics in Yale’s Faculty of Arts and Sciences and a key member of an ...

Based on a new study, the same equipment that was integral to the work of this year’s winners of the Nobel Prize for Physics — gravitational wave detectors — might be able to provide valuable insight ...

Supermassive black holes: Every large galaxy’s got one. But how did they grow so big? Scientists pit the front-running ideas about the growth of supermassive black holes against observational data — a ...

Our universe is a chaotic sea of ripples in space-time called gravitational waves. Astronomers think waves from orbiting pairs of supermassive black holes in distant galaxies are light-years long and ...
