Reply to comment by Aseyhe in In the twin paradox, what happens if the travelling twin never U-turn to get back to earth? (explanation in the post) by PoufPoal

Ok, so, aren't we back in the paradox, where depending on the preferred frame we choose, the shower twin is not the same, then?

But there's no paradox because there is an objective preferred frame in a universe that loops around, which is imposed by the choice of at what times you "connect the opposite edges" of the universe.
