All we have to do to make it solvable is to introduce
a high but finite acceleration for a short time at turnaround.

But no!
You don't pay any attention to what I'm telling you.
You've decided to say that in RR everything is fine, that everything is acceptable, that everything is true, and that you should definitely not say anything.
From then on, it turns into religious fundamentalism.
I explained RR like no one had explained it before, and instead of being interested, everyone is playing the monkey by opposing me with anything....
Pffff...
Where did you see an infinite acceleration?
In the example I gave, the U-turn takes 40 hours in Terrence's frame of reference (24 in Stella's).
It's certainly a huge acceleration, but it's not infinite.
You've decided not to listen to me.
So we're inevitably going around in circles.
This is not new, I have been explaining for forty years how to correctly understand this theory which is not so complicated (we do not even need an integral or a tangent for the whole theory).
The problem is not that "Richard Hachel's theory is wrong", it is "We do not want Richard Hachel to talk to us about that".
We live in a world of sick people.
Furthermore, you do like Python, you criticize but without ever answering the question.
How far is the earth from Stella, at the moment when, after 9 years, and after having seen it flee behind her at 0.444c, Stella will start to brake to begin her U-turn?
Is it 4 ly, or is it not 4 ly?
How far is the earth from Stella, quad, the U-turn completed, she is again at 0.8c, but towards the earth?
Is it 36 ​​ly, or is it not 36 ly?
We must still take responsibility and say things?
How far does Stella see the earth?
What are these distances?
