Not to seem rude in with a tardy response to you other post
but you totally missed the storage element of a TBC.

I think the recorder player example will prompt a
differerent set of questions (or none :o) )
when you include all the elements.

Just imagine a tape device to give you 4 seconds
to kill an announcer's profanity but the motors
are adjustable and the basket holds years instead
of seconds of tape.

But when we get back from our trip around alpha centari
and we have been saving up tape until we have enough to play back 'at
original transmission rate', we have been experiencing LONG periods
during which we could not play the tape
or we have been getting spaced out
words.

When we arrive home, we still have a large pile of unplayed tape.

OK... Now we are on the same page with the scenario.


That pile of unplayed tape represents the missing ticks.

There was a clock and calendar behind the announcer.
Look at the tape in the buffer-basket and let it represent
what it is.

It represents the cycles of molecular vibration that never took place.

It might if molecular vibration made headline news during
the voyage but can you depend on that? < half jesting>


Once we have returned to earth, that pile can never go away because
recording and playback continues at the same speed.

Yes... our traveler doesn't like fast or slow video so
he can't play catch-up.

Since we can ask sue to fill us in on 'how the story ended', we don't
need to play it. We clip it out and throw it away, but it represents
several years of our time.

Do you see any way to get back those missing ticks?

Yes... I discussed it in the second part.
Start the experiment twins-apart.
shake hands at half-time.
End the experiment twins-apart.

But that is an entirely different experiment and a symmetrical situation.
He gains ticks on the way in and loses them on the way out. The same number
of ticks.

In the original problem, he loses ticks on the way out AND he loses ticks
on the way back.
He actually loses the same number on the way out as on the way back but the
Doppler explanation has him lose more on the way out.


BTW Long baseline interferometers uses a similar
technique to synchronise the ~receivers~.

Known patterns are correlated by adjusting the
speed of one player to match patterns on the
other player.

But that doesn't solve the problem of the missing ticks.
(I am not happy with your "visually younger" until he looks away from the
monitor, ether. I say he is REALLY younger then and when he returns to
earth he can confirm it by comparing the elapsed time shown by his on board
computer with Sue's computer's clock time.

You are pretending that those ticks are not real because Einstein used sqrt
(-1) on the time axis but those ticks are just as real as any other ticks.
