Re: "Time" vs "physical time"

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 ΔTo=4.44ms during a synchronization that nevertheless appears perfectly established.

 Is this an incredible convoluted attempt to say that the transit time
for light to go through the tunnel from Oslo to Paris or vice versa
is  ≈ 4.44 ms ?
 What is ridiculous about this simple fact?

Yes and no.
If a professor of Newtonian physics asks Richard Hachel the question: "How long will it take for light to cross the tunnel and go from Paris to Oslo, or from Oslo to Paris?". He will be answered 4.44ms.
If a professor of quantum physics asks the same question, Dr. Hachel (because he is crazy) will answer: "Both 8.88ms and 0 ms."
And all three answers will be correct.
