Physics is supposed to be predictable. Drop a ball, and gravity pulls it down. Heat water, and it boils. Light travels in straight lines. Yet throughout history, scientists have encountered ...

Somewhere between the microscopic realm of elementary particles and the macroscopic world of human beings, something strange ...

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 ...

Physicists have put a decades-old idea about why the strange rules of quantum mechanics disappear in our everyday world to ...

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 Einstein's general relativity explain how the Universe works at the tiniest ...

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 effect of gravity on a falling quantum object for the first time. The result ...
