How to have light move faster than C

That’s because you don’t understand what GR predicts. Note that this page is directly linked to [the one you posted](Experimental Basis of Special Relativity Hypothesis).

I would argue that Einstein synchronization of two clocks is equivalent to:

  • taking a third clock
  • placing clock 3 next to clock 1
  • setting clock 3’s time to clock 1’s time
  • moving clock 3 as slowly as possible (in order to avoid relative time dilation) to clock 2
  • setting clock 2’s time to clock 3’s time
    (source)

and:

  • that makes more sense than synchronizing two clocks and then moving them around
  • SR’s definitions are a part of the theory, because they affect its results; you can’t change its definitions and then say the theory is wrong because of changes you made to it (well, obviously, you just did, but hopefully you can see why this is wrong)

P.S. Your not understanding the math doesn’t make the math go away. E.g., Itself’s demonstration that Lorentz transformations imply the speed of light is constant for all observers in inertial frames still holds. Maybe you can get your scientist friend, who totally really exists, to do the math for you? It’s post 187.
