That's the problem with the conventional view of FTL phenomena.
It comes from the Lorentz transform:
(1) dx' = gamma(dx - v dt)
(2) dt' = gamma(dt - v dx/c^2)
From that comes
dx'/dt' = u' = (dx - v dt)/(dt - v dx/c^2)
u' = (u - v)/(1 - uv/c^2)
u' becomes infinite when u = c^2/v, and infinity is a red flag
in physics. It means that the math becomes useless at and beyond
that point. Physicists, who should know better, have persisted
into that real and come up with all kinds of frivolous assertions
Absolutely.
like time going backwards, negative energy, causality violation
and a "reinterpretation principle."
Yes, all this is not very normal.
Pour ce qui est des transformations de Poincaré-Lorentz, données par le fameux mathématicien français,
qui était plus fort que Newton, Einstein et Leibniz réunis, elles conduisent directement à:

This is a formula that is part of standard SR (i.e. Einstein), unrelated to your idiotic rant.
You've done that before, numerous time. You want a medal for that?
