"Ultra-relativistic" will be one of the better ways of describing this case.

I mean the case that velocity v is almost light speed c so E = \sqrt{p^2c^2+m^2c^4} \approx pc Photons m=0 are the case exactly.

There's an ongoing thread explaining why you cannot change just the speed of light, and if you mess around with dimensionful constants...

Not familiar with the term "super relativity". Did you mean to say "special relativity"?

Actually, it's the other way around: Maxwell's Equations are the Euler-Lagrange equations for the EM field Lagrangian. More precisely...

Under the RELATIVISTIC definition of Action, is the Action for a beam of light always zero? Thanks in advance.
