This seems like crap, but I found an article at the LANL site that was talking about this. Surely radio waves going FTL *is* information going FTL? This should be impossible. An April Fool's joke or something?

"If you take a laser and shine it on the moon and swing it rather gently, for example, the spot on the moon travels faster than the speed of light..."
Well, no. It doesn't. There's a spot in one location, and then there's a spot in a different location. The distance and time involved might require a speed greater than c to travel, but nothing is actually doing that travelling.
Also, the author repeatedly uses the word "phenomenon" as if it were plural.
