Dec 28, 2016 at 8:46 comment added user130529 BTW, would you have the same problem with the simplified (and meaningless) variant of the twin paradox where the twins start both flying in opposite directions, both decelerate, change direction and come back home (all this done symmetrically), where they observe ... that nothing has happened, they are still exactly the same age?
Dec 28, 2016 at 8:08 comment added user130529 yes, why not adding your scheme, and telling what is the point that you do not understand? As it is, I don't understand exactly what you do not understand (as far as you said that you perfectly understand the symmetry of Lorentz equations, which is all it seems about).
Dec 27, 2016 at 22:50 comment added Cheers and hth. - Alf @claudechuber: It's an incorrect understanding that this question presupposes one conclusion. I wouldn't have asked it if I had a ready conclusion. I think you're wrong that the question could be more precise, but by adding the description of a measurement scheme, which doesn't change the physics, I realized that it could be way more clear in the sense of not leaving so much room for hand-waiving in answers. ;-) Unfortunately, with less room for imagined unspecified effects, the current answers look less satisfying to me. :(
Dec 27, 2016 at 18:19 comment added user130529 If the paths are different, why are you surprised that the ticks are not synchronized? Did you try sketching a space-time graphic similar to the one I linked in a comment below? Maybe your question would benefit being rephrased more precisely.
