What is very simple; in the perfect and complete demonstration of the Langevin traveler, it is Terrence's vision of things.
We must take things by considering spatial anisochrony, and in
Terrence's
frame of reference, we just have to treat things as if we were treating
them by telescope, and by using the Doppler effect.
All relativistic physicists succeed, all of them.
And we will all have the same thing.
On this subject, if someone wants to use these images, they can do it.
There is no risk, they are completely correct, and recognized by all.
It is very simple.
This is how it must be done.
The highlight of the show, the sublime beauty is not here.
The highlight of the show is when we will do exactly the same thing for Stella and put ourselves in her place, in a Hachel version colorized technocolor.
And that will be something never seen before anywhere.
But first, I want to show with this first part that I am not an idiot,
and
that I treat things like everyone else.
Vision of things by Terrence (easy)

Just
how would an expedition to TC measure time? Since a time at TC is
specified,
we must assume an earlier expedition arrived there. One way to set the
time
there would be to carry their chronometer with them, which began the
journey
synchronized with Earth time. Let's say they left Earth in 1960. At
0.8c,
their time of arrival would be 1969 (ignoring acceleration and
deceleration).
Earth time would be 1975. So TC time would be behind Earth time by 6
years,
not 12 years.
Only 40 years? I started working SR problems 64 years ago!
In the meantime I earned engineering, mathematics and physics
degrees.

C'est parfaitement correct.

Absolutely.
I beg you to breathe and blow.
When dealing with Dr. Hachel, you must first listen to him
and then respond with control.
It is true that in your example (departure 1960, speed Vo=0.8c)
the rocket will arrive with a watch that will mark 1969.
Everyone says the same thing, and so do I.
I say that FOR the rocket, the rocket's watch marks 1969.
I say that FOR the earth, the rocket's watch marks 1969.
That is LOGICAL.
BUT two other questions will arise:
1. What time is it on earth FOR the rocket when the fact
happens?
2. What time is it on earth FOR the earth when the fact
happens?
These two questions are very different, and already require
much more attention than the first two, because the answers
given are most often wrong (since the bigwigs of physics do
not understand THEIR theory correctly).
Earth time would be 1975. So TC time would be behind Earthtime by 6 years, not 12 years.
No.
You do not understand your own example.
In your example, when the rocket reaches its goal, we neglect
the short-term accelerations, Stella's watch marks 1969. It
crossed the 12 ly in 9 years of proper time.
But the terrestrial watch FOR the earth marks 1987!!!
The fact takes place in 1987 (and not in 1975) as one
stupidly thinks when one understands nothing,
but nothing at all of Hachel's work for 40 years on
the simple and coherent geometry of the RR.

Nope. The ship started from Earth in 1960 going 0.8c. It
traveled 12 LYrs, so according to Earth time it would take
12/.8 = 15 years.

Whaaaooo...
That's very good.
I sincerely congratulate you.
It is therefore highly probable that you surpass me by a lot
in math and physics. It is therefore an honor for me to be
able to correspond with you.

Well, I can't say that I wasn't a bit naive 60 years ago :-)
