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 ...

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

A team of physicists has done something that sounds impossible: they filmed points of absolute darkness racing through a beam ...

A dark point inside a wave of light sounds like a contradiction. It is also something researchers say they have now viewed in ...

Scientists experimentally confirmed what we’ve known to be true for half a century—darkness can “travel” faster than light.

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 ...

Scientists broadly deem faster-than-light transmission of mass or information impossible, as it would violate the laws of ...

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 ...
