You claim that clocks in Norway and France are not synchronous
even if both show the time UTC + 2h because of the universal
anisochrony.
 
The question is about your anisochrony, so please read this and
answer the questions.
 
I leave Oslo Airport (Gardemoen Airport) when the watch on the airport
shows 12.00.00
I arrive at Paris Airport (Charles De Gaulle Airport) when the watch
on the airport shows 13.30.32.
 
The difference is T = 1h 30m 32s
Is this a real time, or is it impossible to know the real time
because of the universal anisochrony?
 
The distance in the ground frame between the airports is L = 1358.03 km.
Is the real speed of the plane in the ground frame v = L/T = 900 km/h,
or is it impossible to know the real speed of the plane because
of the universal anisochrony?
 
 
The question is simple:
Is it possible to calculate the real duration of the journey
by comparing the reading of the clock in Oslo at the departure
and the reading of the clock in Paris at arrival?
 
Yes or no, please.
 
I can understand why you find it very hard to answer
questions when they are taken from practical scenarios
in the real world, and not from your fantasy world.

No, it is not difficult to answer your question, it is simply not very
practical.
Discussing relativistic times with planes whose speeds are very Newtonian
is quite difficult.
Paris to Oslo and vice versa?

So it is evasions, rather than yes or no.
FYI, you failed the test.

Can you reformulate your question using a vast underground tunnel between
Paris and Oslo, in which we could launch particles at high speed from
We assume that the length of the tunnel would be 1320 kms.
L= 13.2.10^5m
c=3.10^8m/s
(1/c)=3.333ns/m
There exists, between Paris and Oslo (the notion of universal present time
being finally understood as ridiculous and abstract in any inertial frame
of reference) a reciprocal delay of information, of real present of
universe, of ?To=4.44ms during a synchronization that nevertheless
appears perfectly established.

Your lack of physics knowledge is showing again.
Precisely this experiment has already been done,
between CERN and Gan Sasso, middle Italy, with high energy neutrinos.
(so no tunnel needed)
The atomic clocks at CERN and Gran Sasso were synchronised
by refering to the GPS sats that were visible simultaneously
from both places.

Does your peculiar physics predict a measured speed of c
for the highly relativistic neutrinos,
and if not, what else?
