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

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...

A dark point inside a wave of light sounds like a contradiction. It is also something researchers say they have now viewed in real time, moving so quickly that, by one measure, it outran light itself.

Physicists have directly tracked tiny points of darkness in laser light racing faster than light itself, without breaking ...

An unexpected mathematical connection between a special kind of mechanical motion and the behavior of light has been uncovered by three RIKEN physicists1. This strange link could help physicists to ...

More than a century before quantum mechanics was born, Irish mathematician William Rowan Hamilton stumbled onto an idea that would quietly foreshadow one of the deepest truths in physics. While ...

Photons are particles of light, or waves, or something like that, right? [Mithuna Yoganathan] explains this conundrum in more detail than you probably got in your high school physics class. While ...

According to the studies of quantum mechanics, light can act simultaneously as a particle and a wave. However, scientists have never been able to capture light in both of its forms at the same time— ...
