In another ways, you do not understand what science is all about.

This is irrelevant to what we are talking about. Stop going off on a
tangent again.

Let me try one more time to explain this one to you. I want you to open
your eyes this time and stop daydreaming about any abstract whacko stuff.
Lorentz Transform as is fails if the two frames of references have their own
values of the speed of light in vacuum in the first place regardless of how
fast the relative speed of each frame is from the other. Get it?

Although the number of electrons are conserved, who said the strength of the
charge is independent of the frame's local speed of light. Do you want to
prove to me mathematically that the strength of charge is independent of the
speed of light? I can prove to you that the strength of a charge in
dependent of the speed of light.
