Perhaps a better version of your analogy would be this:
A metal pole is used to transfer information from one end to the other. A guy on one end is shaking the bar, and pushing and pulling it. This is detected by the guy in the other end. Life goes past smoothly, and this technique of information transfer is perfected. Then, suddenly, some smart asshole comes in and shows these guys that they can also twist the pole, essentially giving a new channel on which to transfer information.
Nothing is faster than the speed of light ... To prove this to yourself, try opening the refrigerator door before the light comes on.
