Physicists in the last ten years have accomplished an incredible feat; they have slowed and even stopped light using ultra cold plasmas. The light is absorbed in the plasma and does not radiate again until a laser beam perpendicular to the original path of the first light beam irradiates the ultra cold plasma and excites to it reemit the light along its original path. Since the motion of light in a sense defines our local perception of time we might say that these experiments have slowed...
