 I said : THREE YEARS AND 40 HOURS !!!!!

Damn, do you not understand anything at all or are you doing it on 
purpose?
Pfffff...
I repeat things of fantastic conceptual beauty and obvious physical 
reality as long as one can experience the SR to the end.

When Stella reaches the end of her outward journey. She is 9 years old
on his watch. On earth, for her, only THREE years really passed. ACTUALLY 
THREE YEARS.
It will rotate in a 24-hour day around its aphelion, and it returns on the 
other side, still at 0.8c, and rushes towards the earth.
She aged 24 hours during the U-turn.
She then sees the earth which now marks 40 more hours.
OR three years and 40 hours.

That's why I say that not much happens during the U-turn, and that 
hundreds of crazy heads contradict me because they didn't understand 
anything at all.

And on Terrence's side, what happens during the U-turn?
Nothing more either or almost.
He sees Stella, aged nine, making her U-turn in 40 hours (but with 
Stella's watch which will only age 24 hours). She emerges from the U-turn 
aged 9 years and 24 hours, while he has
(breathe-exhale) 27 years and 40 hours.

Paul, Paul, I beg you to have three cups of coffee, because this is only 
the beginning of the understanding that you will be able to achieve, if 
you UNDERSTAND what I am saying.

Afterwards, there will be the coup de grace with the notion of symmetry 
and reciprocity of the effects of relativistic physics on DISTANCES.

I assure you that it's heavy stuff, that it's far from what Einstein said, 
and if you don't make the effort to understand things that are however 
simple, we're not going to get there.
