Greetings. An acquaintance of mine called me up with a question regarding the speed of light and information transfer. While I realize that his proposal couldn't work, I am not a physicist and I can't get him to believe me. Can someone out there send me a clear explanation of the physics involved in this problem that he *might* be willing to accept? The problem: transmitting information faster than the speed of light. His idea is as follows. Assume the existence of an extremely thin but very strong and non-elastic straight taut wire one light year in length in a vacuum. Person A is holding one end of this wire (don't worry about the vacuum!) and person B is holding the other end. Now, person A tugs his end of the wire 0.5 inches toward himself. The question is, why wouldn't person B feel the tug almost instantaneously, thusly resulting in an information transfer *much* faster than the speed of light? I've tried to explain this in several ways, but apparently I'm not very convincing on this topic. Would any of you care to take a stab at this guy? I'll forward any responses onward to him. Please reply by mail; I am not in this newsgroup. Thanks much. --Lauren-- {decvax,ihnp4,harpo,allegra,ucbvax!lbl-csam,randvax}!vortex!lauren
