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

Scientists pushed photons across the universe to test the speed of light—and found Einstein’s cosmic speed limit still holds ...

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 ...

(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 ...

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 ...

For more than 100 years, scientists have debated one of the strangest mysteries in physics: Can two particles far apart somehow “talk” to each other instantly? Albert Einstein didn’t think so. He ...

In a striking display of quantum physics, a team of researchers has recreated one of science’s most legendary experiments—with unprecedented precision. At MIT, scientists cooled thousands of atoms to ...

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 ...
