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 ...

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 ...

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

Does gravity act equally on all particles in the universe, or are there differences between ordinary and exotic matter?
