When two particles are entangled, the state of one is tied to the state of the other. Victor de Schwanberg/Science Photo Library via Getty Images The 2022 Nobel Prize in physics recognized three ...

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 ...

The constancy of the speed of light is a pillar of modern physics, but questions persist about its absolute universality. Advanced theories, seeking to unify general relativity and quantum mechanics, ...

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 ...

Athought experiment at the heart of an argument between famed physicists Albert Einstein and Niels Bohr in 1927 has finally ...

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 ...

GAITHERSBURG — Albert Einstein was correct in his prediction that E=mc2, according to scientists at the Commerce Department’s National Institute of Standards and Technology (NIST) and the ...

Following his death in 1955, Albert Einstein's brain was removed, cut into 240 pieces and slowly distributed to scientists around the world. But where is Einstein's brain now? When you purchase ...

One of the most counter-intuitive notions in physics is that all objects fall at the same rate, regardless of mass, aka the equivalence principle. This was memorably illustrated in 1971 by NASA Apollo ...

Einstein was awarded the 1921 Nobel Prize for a theory that half of the people might not even have heard of. His Theory of ...
