Did you know it? If you did why did you not see that c+c=c is not a
theorem of SR?

Ah, you did not know it! Read any elementary textt book on relativity
theory. It is advatised as a "revoultion" of Einstein!

I made nothing up. You do not undertsand the logic. Having no slope
and having slope which is zero are totally different things! The same
applies to having no rest mass and having restmass which is zero.
Einstein could not see this difference. As photon has no rest frame,
in SR, photon should not have rest mass. This is different from that
photon has rest mass and it is zero! Just clear thinking chap.

Why we need evidences. This is concerned about the theory SR itself.
It is known as meta theory of SR. You must learn the distinction
between empirical issues and metaptheoretical issues. You are not
ready for participating in a huigh powered discussion like this.

The standard of mathematical education now is way more ahead of
Einstein's time. Even a good undergarduate maths student is way more
advanced mathematically than Einstein or Minkowski. Some worship
Einstein and Minkowski. Pity.
