Faster-than-light particles have spent decades in physics as both temptation and warning. They offered a way to test the ...

When an object moves extremely fast—close to the speed of light—certain basic assumptions that we take for granted no longer apply. This is the central consequence of Albert Einstein's special theory ...

The speed of light remains one of physics’ firmest assumptions, but scientists still test whether it ever shifts under ...

Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

A new study just added an interesting twist to the complicated history of the physics theory.

Physics has a problem—their key models of quantum theory and the theory of relativity do not fit together. Now, Dr. Wolfgang Wieland from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) is ...

A century ago, Albert Einstein became famous. Sure, he was already well-known among physicists. But the world at large learned his name only after November 1919, when news broke that his theory of ...

In Newtonian physics, space and time had their independent identities, and nobody ever got them mixed up. It was with the theory of relativity, put together in the early 20th century, that talking ...

New tweak to Einstein's relativity could transform our understanding of the Big Bang 'Collective hum' of black holes could settle the debate over new physics Physicists find possible errors in ...
