Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

Two landmark quantum experiments have sharpened one of the oldest arguments in modern physics, and the verdict is not kind to ...

Can a photon be caught behaving like a wave and a particle in the same run of an experiment? For almost a century, that ...

Researchers have finally resolved a century-old debate over the famous "double slit" experiment, according to new research.

Scientists in China have performed an experiment first proposed by Albert Einstein almost a century ago when he sought to disprove the quantum mechanical principle of complementarity put forth by ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

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 ...

A single atom as a movable slit: Researchers realize Einstein's thought experiment in original form, observing quantum-classical transition.

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 ...

How would Einstein have reacted to Bell’s theorem and the experimental results derived from it? Alain Aspect’s new ...

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 fiction. But ...
