Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that describe gravity, quantum fields and the structure of spacetime now allow ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

In this last part of our series on recently digitized books from the Wenner Collection, we are focusing on works that ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

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 ...

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 ...

The big thinkers at Aperture explain relativity and how it warps the fabric of spacetime. Tom Cruise visited 'Star Wars: ...

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 ...

PHYSICS, RELATIVITY, AND SCIENCE’S WELL-KNOWN LIBERAL BIAS…. This was making the rounds a bit yesterday, and it’s awfully amusing. Conservapedia, a right-wing alternative to Wikipedia, has all kinds ...
