For more than a century, the double-slit experiment has been the sharpest test of what reality is made of, and of whether ...

Quantum mechanics is weird. When you think you have reached the bottom of its weirdness, you always discover a new ...

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

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

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 ...

"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of ...

(via Sabine Hossenfelder) The double-slit experiment is a famous quantum physics experiment that shows that light exhibits behavior of both a particle and a wave. In a new paper, researchers claim ...

A new theory of "dark photons" attempted to explain a centuries-old experiment in a new way this year, in an effort to change ...

A photon was apparently detected in two places at once in a twist on the classic double-slit experiment, but many physicists ...
