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 ...

Imagine a juggler tossing balls into the air. The art of juggling is a dance between motion and pause, where the ball’s speed ...

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 ...

Michio Kaku explores the eureka moment when Einstein came up with special relativity, the theory that spawned E = mc2. ByMichio Kaku Tuesday, October 11, 2005 NOVA Einstein realized that the world ...

Nonlocality is a phenomenon that has gained a lot of attention within the physics community over the past few decades. In what Einstein described as “spooky action at a distance,” the implications of ...

With World War I raging on throughout Europe, Hilbert could be found sitting in his office at the great university at Göttingen trying and trying again to understand one idea—Einstein’s new theory of ...

Taken from the August 2021 issue of Physics World where it first appeared under the headline "Relativity, at top speed". Laura Hiscott reviews Reimagining Time: a Light-Speed Tour of Einstein’s Theory ...

A bizarre "cosmic glitch" in the theory of how the gravity of the universe works may have been mended. The strange glitch in Einstein's description of gravity in his theory of general relativity may ...

Entanglement, like many quantum effects, violates some of our deepest intuitions about the world. It may also undermine Einstein's special theory of relativity Our intuition, going back forever, is ...

Physics is weird. There is no denying that. Particles that don’t exist except as probabilities; time that changes according to how fast you’re moving; cats that are both alive and dead until you open ...
