[QUOTE="pixel, post: 5450582, member: 566143"] Say there are two events, A and B, and according to you A causes B. So for instance A could be someone throwing a switch at one location and B could be a light coming on at another location. It can be shown that if the transmission of the signal from the one location to the other travels faster than the speed of light, then there exists another frame of reference, traveling at some speed relative to you, for which event B occurs before event A. That violates causality - in that frame an observer would determine that the light came on before the switch was thrown. [/QUOTE]
