Two black holes spiraled into each other in a spectacular collision 1.3 billion years ago. The black holes in a galaxy far, far away then merged, vibrated and produced gravitational waves, a type of ...

Einstein's theory of gravity, general relativity, has passed all tests with predictions that are spot-on. One prediction that remains is "gravitational wave memory"—the prediction that a passing ...

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 ...

In 2023, physicists were awed to find nearly imperceptible ripples in the fabric of space and time — united as an entity known as spacetime. They were ripples discovered in association with ...

The Earth’s atmosphere is host to a diverse spectrum of wave phenomena, among which acoustic-gravity waves occupy a pivotal role. These waves arise from the interplay between compressional (acoustic) ...

In about 11 years, one of humankind’s most ambitious missions is set to launch into space. Decades in the making, the Laser Interferometer Space Antenna, or LISA, could revolutionize our understanding ...

Ten years ago, scientists heard the universe rumble for the first time. That first discovery of gravitational waves proved a key prediction from Albert Einstein's theory of general relativity and ...
