Within a nanometer-scale device, visible light travels infinitely fast—by one measure—a team of physicists and engineers reports. The gizmo won't lead to instantaneous communication—the famous speed limit of Albert Einstein's theory of relativity remains in force—but it could have a variety of uses, including serving as an element in a type of optical circuitry.
