This example is not necessarily a case of something actually moving faster than c (a signal, or whatever). On possible explanation that I have seen for this phenomenon is analogous to what happens when you shine a flashlight on clouds and move it quickly from one side of the sky to another. The apperant velocity of the spot is very high, but the actual movement that takes place is really quite small. Well, I don't know if this is useful, but I just thought I'd mention it. -Wayne Christopher faustus@berkeley ucbvax!faustus
