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 ...

According to Einstein’s theory of general relativity, gravitational waves warp spacetime. In the process, they could imprint permanent changes, or “gravitational memory,” on their surroundings.

Black hole quantum effects are usually thought to be too small to have any observable signatures. This is indeed the case for heavy black holes, such as the ones detected via gravitational waves by ...

A physicist has proposed a bold experiment that could allow gravitational waves to be manipulated using laser light. By transferring minute amounts of energy between light and gravity, the interaction ...

A team of theoretical physicists has proposed a new way to test one of the most intriguing predictions of Einstein's theory of general relativity: gravitational memory. This effect refers to a ...

Scientists have proposed a surprising new way to detect gravitational waves—by observing how they change the light emitted by atoms. These waves can subtly shift photon frequencies in different ...

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 ...
