You said earlier that a true paradox invalidates a theory. Here you claim that the paradox is NOT solved, which implies that the Theory of Special Relativity is false. Btw: An entirely different situation compared to the Twin Paradox, which turned out to be false, as one of the twins left the common frame of reference and accelerated away (and back); hence confirming the theory of SR. (To note, for good measure: This paradox is solvable in the same way as the twin paradox's is.)
