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 ...

TU Wien researchers have uncovered a quantum twist to the paths particles take through spacetime — one that could finally ...

It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is ...

Quantum theory and general relativity have long described the universe with incompatible languages, one speaking in ...

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 ...

Physicists have demonstrated with unprecedented accuracy that the speed of light remains constant. In 1887, a landmark physics experiment was carried out by American researchers Michelson and Morley.

If you're going to Mars you'd best take along a jar of anti-aging cream because while you're there you're going to age faster ...

Since its introduction by Albert Einstein in 1905 (ref. 1), special relativity has been the accepted theory of local space-time. It not only resolved severe open questions in electrodynamics but ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. Yesterday, I wrote about the core concepts needed to understand quantum ...

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 ...
