I confess I'm away from my desk, traveling in Los Angeles. Various other equally pressing & interesting matters have been left to wait until my return to Oregon. But to continue...Great to receive your reply so quickly.
Ah, but we didn't "weasel out" of the paradox, but comprehensively resolved it. And each of the two different values is perfectly objective, to all observers in that particular frame of reference.In other words, you (following Einstein) are applying SR at your convenience to weasel out of the logical paradox since you now claim that space is contracted for the moving twin (B) but not for the stationary twin (A). Hence even your own excuse disqualifies SR as genuine science because SR created two different, two non-objective values for the distance between Earth and Planet X at the start of the voyage.
