Imagine asking the biggest, most fundamental question of all: what is reality? How would you go about answering it? If you took the scientific approach, you'd go down to the smallest indivisible ...

Physicists in Europe and the US have performed a novel version of the double-slit quantum-interference experiment with single electrons. In the classic version of the experiment, electrons pass ...

(Inside Science) — One of the strangest things about quantum mechanics is that a particle can act like a wave. In particular, in a double-slit experiment, individual particles that are shot through a ...

“Einstein and Bohr would have never thought that this is possible, to perform such an experiment with single atoms and single photons,” said Wolfgang Ketterle, head of the MIT group whose new ...

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 ...

Even younger: illustration of the new double-slit experiment using resonant inelastic X-ray scattering on an iridium oxide crystal. An intense beam of high-energy X-ray photons (violet) hits two ...

Scientists recreated one of the most important experiments in the history of physics—but this time, they used antimatter instead of regular matter. All matter particles have a corresponding antimatter ...
