Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

Right at the brink of a black hole, gravity twists space and time so violently that ordinary physics starts to fall apart.

Gravitational physics has become a truly experimental science as tests of the special and general theories of relativity reach new levels of precision Right on time When I was a first-term graduate ...

A South Korean physicist has proposed a theoretical framework that could support the unification of quantum mechanics and the ...

Santa Claus is not breaking the law. He is just using Einstein's physics to bend the rules of time and deliver presents to ...

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 ...

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 ...

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 ...
