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 ...

Two of the forefathers of quantum theory, Albert Einstein and Niels Bohr, had a famous argument over whether light is a wave ...

Physicists have directly tracked tiny points of darkness in laser light racing faster than light itself, without breaking Einstein’s rules. The new measurements show that these “dark points” in a ...

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 ...

Researchers at the Technion-Israel Institute of Technology have measured “dark points” inside light waves that appear to ...

Dark structures inside light waves can briefly move faster than light without breaking relativity or transmitting energy or information.

(Aitor Diago/Moment/Getty Images) For the first time, physicists have observed that 'holes' in light can move faster than the ...

There has long been a mystery when calculating how an incoming light wave scatters off an object and becomes a modified, outgoing light wave. In particular, the time delay of the transition from one ...
