: Relativity assumes that, rather than predicts it. I think relavitist purists would actually say all that is needed is a maximum velocity, whether that is "c" or something else. Many would not be genuinely surprised if velocities slightly faster than ''c'' are ultimately attained, and ''c'' itself may be changing over time.--[[User:Aschlafly|Andy Schlafly]] 02:36, 25 August 2011 (EDT) | : Relativity assumes that, rather than predicts it.
