The mathematics is the integration of the proper time along the world lines of the two twins. Then it is OBVIOUS they are different. This directly attributable to one of the world lines being less straight than the other. Your being oblivious to the mathematics doesn't mean that this is not a straightforward demonstration shown in many books. Penrose's Road to Reality does this in a half-page, for example. > > On top of that, you can always design an experiment where both twins > do travel with the same acceleration profile. And in this case there is no clock difference upon reunion.

What if the high speed traveling twin continues in a straight line for a trillion years, and returns to the same spot via the curvature of space (assuming the universe is closed), without turning around, hence no acceleration - what does the twin paradox predict then? -- Rich

The universe is flat. No twins are going to leave each other and return without accelerations involved. Don't fool yourself.

The physics (laws of physics) are the same in all inertial reference frames, but that does not mean observations are the same, those depend on relative (NOTE I SAY RELATIVE) positions and velocities with respect (NOTE I SAY WITH RESPECT) to what is being observed.
