Light Behaving Badly: Strange Beams Reveal Hitch in Quantum Mechanics

A hidden property of corkscrew, spiraled beams of light could put a hitch in quantum mechanics. The photons, or light particles, inside these light-based Möbius strips spin with a momentum previously thought to be impossible. The findings could shake up some of the assumptions in quantum mechanics, the rules that govern the menagerie of tiny subatomic particles.
