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

Learn about a recent experiment that could take us one step closer to solving one of physics biggest questions.

The weak equivalence principle (WEP) is central to Einstein's general relativity. It posits that gravity must accelerate ...

Rogue black holes kicked from their galactic lairs are among the surprising predictions made by physicists using powerful computers to solve Einstein's equations of general relativity. David Appell ...

Discover the 25 fundamental physics concepts that govern our universe, from classical mechanics to quantum mysteries.

Einstein’s famous tenet of special relativity — that time slows down on a moving clock — has been verified 10 times more precisely than ever before. The result comes from physicists in Germany and ...

THE quantum realm has always seemed worlds apart from general relativity, Einstein’s theory of gravity. One rules at the atomic scale and smaller; the other reigns supreme across the cosmos. This is ...

Yesterday, I wrote about the core concepts needed to understand quantum physics, which is one of the two pillars of modern physics. The other, of course, is the theory of relativity, the full and ...
