Breathe in, exhale.

Breathe.

When Bella and Stella make their trip, they take the same amount of time. 
Everyone agrees on that.

The calculated time is the same for all physicists in the world, French, 
American, German, Spanish, English, and even Richard Hachel.

Here, 12,915 years old.

I call this time improper time because it does not correspond to the 
proper time of the two rockets and in any system of relativistic Axelian 
or Minkowskian calculations.

It goes without saying that it defines the time between the joint 
departure event of the two rockets and the joint arrival of the two 
rockets.

We have entered into tautology there.
