New research shows that cutting a single particle of light spawns photons all the way to infinity.

A photon is a single particle of light, and under normal circumstances, it can’t be divided. But a photon is also not a particle, in the sense that it does not have a specific location. Instead, it is ...

Photons traveling through a cloud of atoms can emerge so early that they appear to have spent a negative amount of time ...
