You don't understand anything I'm saying...

Pfffff...

I'm not talking about technical precision, I'm talking about a real 
problem linked to the nature of space and time.

This problem is anisochrony, two identical and well-adjusted watches, 
which we slowly and in the same way separate over a distance of 300,000 km 
will be irremediably out of tune.

They will always have the same chronotropy (internal speed of the watch 
mechanism) and for me, who am at the center, they will always mark the 
same time.

But between them, there will be a real time difference due simply to the 
distance. This gap, absolutely real and unavoidable due to the nature of 
space and time, will be one second between these two watches. Each sees 
the other beat at the same speed (they are inertial, stationary) but with 
a strange delay of 1 second.

Physicists do not seem to understand this property, and only understand 
the internal chronotropy when watches are in reciprocal motion, but that 
is not enough. We must also understand anisochrony, which is a real 
phenomenon, of the first degree, unavoidable, and which has nothing to do 
with the speed of light. Information propagates instantly, BUT the present 
moments did not correspond to the departure.
