Physicists have directly linked quantum mechanics and Einstein's gravity theory. An experiment used ultracold atoms in ...

Physicists have directly observed a long-predicted quantum effect of gravity, putting one of Einstein’s foundational ideas to ...

An Einsteinian view of gravity, a curvature in spacetime caused by mass and energy. (ESA/C.Carreau) Quantum mechanics and ...

Scientists measured a predicted quantum phase in freely falling rubidium atoms, finding results consistent with Einstein's ...

A new experiment using ultracold rubidium atoms found that a quantum object in free fall behaves consistently with Einstein's ...

Physics is filled with mysteries - and believe it or not, gravity remains one of them. We rely on gravity to explain things large and small. And yet, at a fundamental level, we still don’t fully ...

Scientists have spotted the first hints that Einstein's formulation of gravity operates in the quantum realm.

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

An international team including Nobel Prize-winning physicist Professor Sir Roger Penrose has observed a long-predicted effect of gravity on a falling quantum object for the first time. The result ...
