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.)

This device invariant becomes a laptop one day. A paradox unsolved is why the SRT allows for special Lorentz effects. Biconditional updates are correlated to bridging physics with string theory. Knowledge gaps exist to be explained, to be even recognized, and then... Next syllabus, thank you! Where is that laptop? !

so I'm sending you a 15' pole to store in your 10' barn. now store it for me without letting it stop or it won't fit anymore! ahh fun in physics.
