No, the numbers are not the same for everyone.
Let's take the case of the Langevin traveler, Vo=0.8c. D=2*12al.

This means that, for an observer on Earth, the duration of the journey, 
which is a number, will be To=D/Vo.

Or To=24/0.8=30 years.

Problem: this is not an invariant. Stella on board the rocket does not 
have the same number as Terrence.

She is 18 years old.

The same is true here, in special relativity explained by Dr. Hachel, 
which is fundamentally different from that taught by Minkowski. 
Fundamentally different.

If we believe in the flat earth theory (today it is the belief in flat 
time and the absolute isochrony of the universe), we will say that for A 
the outward journey is AB/c and the same for the return journey.

And the same for B.

But this way of thinking, even if it is intuitive, even if it seems of the 
most colossal logic, is false.
