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

Perhaps one of the most famous experiments in physics has been giving us the wrong message all these years. For nearly two ...

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

Light has always been the stage on which quantum mechanics performs its strangest tricks, and the double-slit experiment is ...

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

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

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 ...

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 ...

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

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 ...

The original double-slit experiment, performed by Thomas Young in 1801, demonstrated the wave nature of light. When the light—and in later experiments electrons, atoms, and molecules—passed through ...
