Line 48: I quote from the article: ::"Lorentz covariance requires that in two different frames of reference, located at the same event in spacetime but moving relative to each other, all non-gravitational laws must make the same predictions for identical experiments." I'm fairly certain this isn't true on at least two accounts. Firstly, Lorentz covariance applies only to two different '''inertial''' frames of reference. And secondly, not all predictions are the same: even in Galilean relativity, we predict different values of kinetic energy in different reference frames. The situation is similar in special relativity: various physical quantities (energy, momentum, B-field etc) transform (note this is NOT the same!) as components of various ''spacetime vectors''.
