You still don't understand, damn it, no one understands what I'm getting 
at.

Let's start again (I'm going to end up going crazy because of you, and 
your blindness; no one understands, and everyone is acting smart by 
arguing that not understanding is necessarily being smarter than me).

We place two points A and B in the universe, 3.10^8 meters apart.

Richard Hachel says that we will never be able to synchronize them BETWEEN 
THEM because of universal anisochrony. We will only be able to synchronize 
them by convention and for ONE chosen point in the universe.

These two points do not coexist in a global and reciprocal universal 
present moment. BUT SHIT! It's still not difficult to understand.

This belief is an abstract religious thought but false.

It immediately happens (if you think about it a bit) that the path of a 
signal from A to B will not be identical for A and for B.

B will consider that the signal is instantaneous (and he will be right), 
while A will consider that the signal shifts towards the future and will 
note tAB=2 seconds.

We immediately realize that this implies a completely anisochronous 
universe, where everyone measures the time they want, and that generally 
all measured times will be different.

It's not funny, but that's how it is.

It's a bit like the time that flows in a relativistic frame of reference 
compared to another. If we take a thousand frames of reference, the same 
proper time will be transformed into a thousand different improper times. 
Nobody is offended by this, all relativists understand it.

Well, universal anisochrony is not the same. A measures 2 seconds, B 
measures an instantaneous transaction, and each point of the frame of 
reference will measure a really different time.

So we still have to agree on all that. I recently explained that 
Einstein's procedure was abstract, but useful, because it put all this 
little world back in a certain coherence where a point M located at an 
equal distance from the entire chosen universe, observes this universe 
live without distorting anisochrony.

It is this point that makes the law, and defines a "present moment that is 
common to it to measure the times of the universe".
For him, a crucial thing, all displacements are transversal, and only 
transversal. For him, all electromagnetic signals (which are present waves 
for receivers) move at c, and by convention, all observed points exist in 
the same present moment.
This is where this imaginary point is useful, although abstract.
