Researchers split a cold-atom wave in two, held one part still with magnets, let the other fall, and measured the phase shift Einstein’s principle predicts.

UK researchers show that comparing measurements from two atom interferometers can remove laser disturbances and reveal tiny signals from gravitational waves or dark matter.

Non-trivial spacetime shape provides topological protection against quantum fluctuations that should make the constant enormous.

The proposed framework replaces continuous rings with cylindrical structures to create a stable and habitable interior for future spacecraft.

S301 orbits Sagittarius A at 25,000 km/s, close enough that the black hole's rotation twists spacetime. Years of tracking should yield the first direct spin measurement.

Researchers have observed a distant black hole twisting the fabric of the universe as it shreds a star, confirming a century-old prediction made by Albert Einstein about gravity.

Physicists develop FROSTI to enhance LIGO's precision in observing cosmic events by controlling powerful laser distortions.

A new approach uses modern quantum tools and gravitational waves to spot single gravitons, potentially uniting quantum physics with Einstein's gravity theory and opening experiments on quantum gravity.

Tabletop experiment mimics ringdown waves and photon sphere modes to enable controlled study of extreme gravitational effects.

New research introduces quantum geodesics, offering a way to test theories uniting quantum physics and general relativity through observable deviations in space-time trajectories.
