I have shown you Terrence's, speed, position and proper time
measured in Stella's rest frame, as a function of Stella's time.
It is quite simple:
During Stella's time 0y -> 9y, Stella is inertial and so is her frame.
MEASURED IN STELLA'S FRAME, Terrence is moving away at the speed 0.8c, his clock runs slow by 1/γ, and his position is x = 0.8c⋅t_Stella'
So when Stella's clock show 9h, t_Terrence = 5.4y and x = 7.2 ly
During Stella's time 9y -> 9y + 24h, Stella is accelerating towards
Terrence, so Stella's frame is an accelerated frame.
MEASURED IN STELLA'S ACCELERATED FRAME, Terrence will move away
from Stella at high speed, and his clock will run thousands of times
faster than Stella's.
So when Stella's clock shows 9h 12h, t_Terrence = 15y and x = 12ly
When Stella's clock shows 9h 24h, t_Terrence = 24.6y 25.6h
and x = 7.2ly + 19.2lh
During Stella's time 9y 24h - 18y, Stella is inertial and so is her frame.
MEASURED IN STELLA'S FRAME, Terrence is moving away at the speed 0.8c, his clock runs slow by 1/γ, and his position is
x = 7.2ly + 19.2lh + 0.8c⋅t_Stella'
At Stella-s time 18y + 24h Terrence is back.
What is it that you don't understand?
Physicists don't realize that they are practicing artificially.So Stella's rest frame is not the real one, and it isn't hers,
The frame of reference that they attribute to Stella is firstly not the real one. It's not hers, but the frame of reference of a comoving observer placed very far away and observing things transversally.
This is the first problem, but the second will be worse. For the return, we are forced to do the same thing, but here, it's no longer like with Terrence where M1=M2.Ooops. You lost me there!
In Stella's frame of reference, M1 is imaginarily infinitely far from M2. We "jump" from frame of reference, which is neither pretty nor credible. We then "jump" from clocks. And all this is nothing more than a vulgar patch-up to "be even more right".
If we finally wanted to understand things (but we don't want to),So Terrence can't have a speed and position in Stella's rest frame?
we would realize that a frame of reference can only be attributed, in relativity, to a single observer.
This observer is at point O of the frame of reference.And because Stella is NOT in her correct relativistic place, we are forced to apply non-existing subterfuges to validate the passage between two points which are infinitely far away.
In Stella's problem; Stella is NOT in her correct relativistic place, and we are forced to apply non-existent subterfuges (time-gap) to validate the passage from M1 (go) to M2 (return) while ideally these two points are infinitely far away in their respective space-time. We "jump" frames of reference.
I don't practice like that at all.So Stella's rest frame is not the real one, and it isn't hers,
I always stay in Stella's frame of reference, WITH Stella as center and origin. So she NEVER jumps frames of reference. She is always in her frame of reference and at point O.
