Relativistic synchronisation method

It seems that no one has clearly understood the "relativistic problem", and what a "relativistic synchronization method" is.
It seems especially that even Einstein, don't laugh friends, did not understand it, but attacking a living God to denounce him is not easy.
We must always, in all things, try to be fair, try to be true.
It is fair to say that Albert Einstein postulates, without explaining it, the invariance of the speed of the speed of light. It is a postulate.
For Hachel, postulating is not enough. We must explain, at the base, why.
Doctor Hachel, blessed be he and accepted in the Holy Lands of Aôôôllah, peace be upon him, speaks of a universal anisochrony, and claims, blessed be he and accepted in the Holy Lands of Aôôôllah, peace be upon him.
The principle is there, and if we affirm that any receiver receives live, in perfect cosmic simultaneity, in its hyperplane, any electromagnetic signal, it will easily come to mind, that this infinite, instantaneous speed of information is constant for any observer, and that it does not depend on the speed or direction of the source, nor on that of the receiver (which is moreover considered, for him, fixed in his frame of reference).
Once this is accepted (see the pdf of Dr. Hachel, blessed be he and accepted in the Holy Lands of Aôôôllah, peace be upon him) and accepted that the escape velocity of the wave is c/2 for any observer who emits, it comes that in synchronization M, M', M"", the speed of the TRANSVERSELY observed wave, that is to say neutral, will always be the same, and the average of the two other speeds.
We fall back, having explained it, on the constancy of the observable speed (transverse, neutral) of light.
This is what I explain in my pdf, on the question of the relativity of chronotropy after having discussed anisochrony (the primum movens). The moment is relative, chronotropy is relative too. It is a double relativity.
We will see that it is the same thing, with lengths and distances. One last word: it seems that physicists know perfectly well the notion of contraction of lengths and dilation of durations. What is very strange is that they have never been able to take the next step, and apply this also to DISTANCES and INSTANTS.
Or if they do, they do it badly.
