Since you still seem to think that it was Richard Hachel
who discovered this, it is obvious that you do not read
what I and others write to you.

Let's admit it, Paul.
You're wrong, Einstein didn't say anything at all, and always just repeated what Poincaré said, but hey, it doesn't matter, we'll admit that you're right.

Quote from § 1. Definition of Simultaneity:
-------------------------------------------
"If at the point A of space there is a clock, an observer at
A can determine the time values of events in the immediate
proximity of A by finding the positions of the hands which
are simultaneous with these events.
If there is at the point B of space another clock in all
respects resembling the one at A, it is possible for an observer
at B to determine the time values of events in the immediate
neighbourhood of B.
But it is not possible without further assumption to compare,
in respect of time, an event at A with an event at B.
We have so far defined only an “A time” and a “B time.”
We have not defined a common “time” for A and B, for
the latter cannot be defined at all unless we establish
by definition that the “time” required by light to travel
from A to B equals the “time” it requires to travel from B to A.

Well, the gedankenwelt of your idiot guru,
thanks to his incredible stupidity,
is even more chaotic than the reality.
