Hi all, I'm a basic novice at physics so please be gentle :) As I understand it, C (from E = MC2) is the constant representing the maximum speed of information transmission in the theory of relativity. The Speed of Light in a vacume is atributed to C under the theory that, as light has no mass it has therefore the fastest possible attainable speed. (Have I basically got that right?) My query is this:- Theoretically.... If there is an (undetected)energy that travels faster than the speed of light, therefore replacing C in E=MC2, would it effect the existing physics mathematics etc or would the existing math/theories be uneffected?
