 Well, the answer is yes. Einstein said nothing can go faster than the speed of light, and actually that's not quite correct. There are some things which can go faster than the speed of light. If I have two electrons, and they're vibrating in unison, and then I separate them, according to the quantum theory, an umbilical cord, an umbilical cord emerges that connects the two, like a telegraph wire. And if you jiggle one, then the other one senses the fact that its partner has been jiggled.
