A new experiment found that a falling quantum wave behaves just as Einstein’s equivalence principle predicts. The result ...

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

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

Scientists at the University of Ulm, the University of Oxford, and the Ben-Gurion University ...

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

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

An international team built a quantum interferometer, split a single rubidium atom into two simultaneous paths — one falling ...

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 ...

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