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

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 ...

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

Researchers use an updated version of slit experiment, and figure out who was correct between Einstein and Bohrs regarding complimentarity theory.
