I beg you to understand something... When I talk in Vr notation, I'm talking about real speeds (which can take any value). You are talking about speeds observable in a frame of reference which is not that of the mobile, but that of the observer, and therefore you are talking about Vo. It is very obvious, and I have never said the opposite in 40 years of explanations that I wanted to be consistent, that Vo could be greater than c. It’s YOU who made me say it. I never said that. I implore you to show a little more humility when responding to me. To say "Doctor Hachel, you are an idiot, you don't know that we cannot exceed c", is to be both very extravagant, and above all very unhumble. I would not allow myself to make such a stupid and humiliating remark to you. > > The "theory" is obviously Newtonian mechanics with Galilean relativity. Absolutely not. My concepts are ultra-relativistic. Absolutely not newtonian, nor einsteinian. R.H.
