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 ...

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 ...

How did a photon survive a journey of more than 2 billion light-years when, according to known physics, it should have been ...

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

Gravity ties our bodies to planet Earth but it does not define the limits of the soaring human mind. In November 1915 – exactly one century ago – this was proven to be true when Albert Einstein, in a ...

First of all, the prevailing quantum theory, quantum field theory, is fully relativistic from the onset. Relativity is “built into” the theory, so to speak. And it’s the only quantum theory that is ...

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 ...

Einstein showed that time and space are not fixed entities, as they seem to us, but are actually changeable. As Brian Greene explains, it's all based on an observer's state of motion compared to that ...

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 ...
