Scientists find entirely new kind of gravitational wave in unprecedented breakthrough

Scientists have “heard” a chorus of gravitational waves rippling through the universe, in what they say is an unprecedented finding that could fundamentally change our understanding of the universe.

The discovery, described in a range of newly published journal papers, suggests that spacetime is being rocked by intensely powerful gravitational waves all the time. Those waves carry a million times more energy than the one-off bursts of gravitational waves that were detected from a black hole and were themselves hailed as a major breakthrough in our understanding of the universe.

The new results suggest that everything is being slowly shrunk and expanded by a new kind of gravitational wave as they pass through our galaxy. Scientists describe it as being akin to hearing a “symphony” of waves echoing through the universe.

“It’s like a choir, with all these supermassive black hole pairs chiming in at different frequencies,” said Chiara Mingarelli, a scientist who worked on the new findings while an associate research scientist at the Flatiron Institute’s Center for Computational Astrophysics. “This is the first-ever evidence for the gravitational wave background. We’ve opened a new window of observation on the universe.”
