Darkness can travel faster than the speed of light — without breaking Einstein’s relativity

A dark point inside a beam of light should not be much of a traveler. Yet in a new experiment, some of those points appeared ...

How sound and light act alike—and not—at the smallest scale

A world-famous light experiment from 1801 has now been carried out with sound for the first time. Research by physicists in Leiden has produced new insights that could be applied in 5G devices and the ...

Darkness beats light? Einstein was right again as scientists discover darkness moving faster than light without breaking relativity rules

Can darkness really travel faster than light? A surprising new physics experiment suggests it can—at least in a very unusual ...

Universal conservation law governing the wave–particle duality and quantum entanglement

Universal conservation laws of wave–particle–entanglement triad, which describe relations between the wave–particle duality of a quantum system and its entanglement with an ancilla quantum memory, are ...
