A century-old thought experiment on wave–particle duality is brought into the laboratory using a single trapped atom ...

Albert Einstein was right about a shocking among of things, but not necessarily everything.

Albert Einstein was well known for his thought experiments involving complex scientific ideas. Often he used real-world examples that helped non-scientists grasp his theories of relativity. He started ...

Physicists confirm that light has two identities that are impossible to see at once. (Nanowerk News) MIT physicists have performed an idealized version of one of the most famous experiments in quantum ...

(Reuters) - In the world of "Star Trek," the starship Enterprise zips through space using a warp drive that harnesses antimatter. Suffice it to say, such technology remains in the realm of science ...

Can a photon be caught behaving like a wave and a particle in the same run of an experiment? For almost a century, that question sat at the heart of a famous disagreement between Albert Einstein and ...

The faster you move, the stranger time becomes. By imagining how light travels to two people moving at different speeds, Einstein showed that time isn’t absolute. His thought experiment revealed that ...

The most precise test yet of one of Albert Einstein’s ideas about gravity has once again shown he was right. The finding means that physicists may need experiments that are even more accurate to ...
