When you don't fully understand a theory, you have to start with its
basics.
What is needed, above all, is never to state words, notions, concepts
without a precise idea of ​​what you are saying.
This is, unfortunately, what is most often done.
No relativistic physicist in the world (where they are hiding) is capable
of explaining the evolutions of the Langevin paradox (which remains
current and on which cranks and trolls of all kinds have a nice game to
come over). They do not understand what they are talking about, and drown
their fish under a haze of words like "when the reference frame is jumped,
the needles go crazy".
I have never used such words, nor been so vague in the terms. So the
question is: "Who is using the best principles?"
I take this opportunity to present here a very important transformation
that all students should know by heart, and which is that of the vision of
the universe by two (or more) momentarily joint observers.
This transformation is useful, beautiful, and true.
It is still necessary to understand, like me, who disseminated it, clearly
the meaning and the terms.
t and t 'are equal to 0. It is the moment when the two (or more) observers
cross each other and trigger their watch. x, y, z represent the universe
they are observing at this moment (it is exactly the same but the
specified spatial deformations).
To, To 'represent the instants when the events observed live by the
observers took place.
Be careful not to mislead the signs. To and To 'are always negative in the
present case of the crossing t' = t = 0.
In R, t=0, To=-sqrt(x²+y²+z²)/c
In R', t'=0, To'=-sqrt(x'²+y²+z²)/c

You seriously need to learn how to write.
Remove all unnecessary cries.
Be concise.

Like, your current post, can be greatly simplified just by saying:

" t and t 'are equal to 0. It is the moment when the two observers
cross each other and trigger their watch.
To, To 'represent the instants when the events observed live by the
observers took place.
Be careful not to mislead the signs. To and To 'are always negative in the
present case of the crossing t' = t = 0.
In R, t=0, To=-sqrt(x²+y²+z²)/c
In R', t'=0, To'=-sqrt(x'²+y²+z²)/c "

And all that can be even stated much simpler with less words. Again, learn to write.
