Scientists in China have performed an experiment first proposed by Albert Einstein almost a century ago when he sought to ...

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

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

Physicists in China have brought one of Einstein’s thought experiments into reality—but not quite with the outcome he hoped ...

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

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

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

In 1920, Danish physicist Niels Bohr proposed that although light (photons) has a dual nature, behaving as both particle and wave, it’s impossible to observe this duality at the same time. This is ...

Several weeks ago I picked up “The Elegant Universe” because I thought it would have information on The Ultimate Theory. Soon afterwards, I picked up “How to Teach Physics To Your Dog” in order to get ...

Schematic of a single photon with zero angular momentum (green) splitting into two photons (red) with either zero or opposite angular momenta (sketched through the spatially varying color), which adds ...
