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

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 ...

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 ...

Almost a century after the legendary debate between Albert Einstein and Niels Bohr, a team led by Jian-Wei Pan from the University of Science and Technology of China has brought the famous ...

To understand gravity, Einstein had to rethink space and time as a single connected fabric. He showed that mass bends this fabric, guiding how everything moves. NOVA is available to stream on pbs.org ...

Over a century ago, Albert Einstein found a paradox during a thought experiment involving mirrors moving at the speed of light. Now, a new set of calculations may have unravelled it. “If you search ...
