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

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

Physicists split an atomic wave between free fall and a stationary path, revealing a quantum phase predicted nearly a century ago.

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 ...

For more than a century, quantum mechanics and Albert Einstein’s theory of general relativity have each passed countless tests, but physicists have struggled to reconcile the two. Now, scientists in ...

An international team including Nobel Prize-winning physicist Professor Sir Roger Penrose has observed a long-predicted ...
