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 significant study by LVK involving 168 black hole mergers shows no inconsistencies with Einstein’s general relativity, ...

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 ...

Atmospheric gravity waves are oscillations in the neutral atmosphere driven by buoyancy restoring forces, which can propagate from tropospheric and stratospheric sources into the upper atmosphere and ...

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 ...

If you know a little bit about stars, you've probably heard that the most massive ones end their lives by exploding: they go supernova. The end product of those events is an extremely dense object, ...

An intriguing new study argues that current detection methods might be far, far more difficult than they have to be. Share on Facebook (opens in a new window) Share on X (opens in a new window) Share ...

A fleeting secondary tone was detected in the recent gravitational wave signal, offering a rare chance to test the Kerr solution, which describes a rotating black hole using only mass and spin.

General relativity describes gravity not as a force but as the curvature of spacetime produced by mass and energy. Matter tells spacetime how to curve, and this curved geometry guides the motion of ...
