Physicists sometimes say that a beam of light traveling through space is like a “great smoky dragon.” One can know much about where the light comes from (the dragon’s tail) and where it is seen (the dragon’s head), yet still know precious little about the journey in between (the dragon’s mysterious, nebulous body). As light Read More
