Post by Richard HachelWhat 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.

Very pretty pictures but sorry, old friend, they are incorrect.
First of all, the time between Earth and Tau Ceti need not be 12 years.
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.
The first expedition could calculate the time on earth using SR to set
their
chronometer to Earth time. That would get them much better
synchronization,
but any uncertainty in their speed or the distance traveled would leave
some
residual errors. There's a better way to get exact synchronization.
I used the impossible embarkation time for the first expedition of 1960
for
a special reason. When this expedition arrives, they send a signal back
to earth. Earth immediately sends a signal back, telling them the time
on
Earth (1987). It arrives back 24 years from being originated (1999).
The expedition now knows the exact distance between Earth and TC, and
they
can now synchronize their chronometer with Earth time. So when the ship
leaves Earth in 2000, the time on TC will be 2000, not 1988.
