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

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

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

Imperial physicists have recreated the famous double-slit experiment, which showed light behaving as particles and a wave, in time rather than space. The experiment relies on materials that can change ...

God does not play dice with the universe,” Albert Einstein famously declared in 1927, sparking one of the most enduring ...

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

More than 200 years ago, the English scientist Thomas Young carried out a famous test known as the “double-slit experiment.” He shone a beam of light at a screen with two slits in it, and observed ...

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

Quantum physics is the realm of the strange. And one of the strangest discoveries in the field is also one of the most fundamental: Particles fired at barriers with two slits in them can act like ...

We’ve all seen recreations of the famous double-slit experiment, which showed that light can behave both as a wave and as a particle. Or rather, it’s likely that what we’ve seen is the results of the ...
