Physicists including Roger Penrose observed gravity’s effect on a falling quantum object for the first time, confirming ...

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

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

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

Physicists have proven a 100-year-old prediction of relativity by showing that Einstein's equivalence principle holds at ...

On 2 September, an international team reported the first direct measurement of the quantum phase that accumulates when atoms fall freely under gravity. The result, published in Science Advances, shows ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged. This theory tries to ...

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 ...
