Twins Paradox
Can either physics.stackexchange thread (one referencing the other) provide a satisfactory answer to the Twins Paradox? It doesn't appear so to me.

The predictable "possible responses" to a Relativity Challenge are covered in the above threads and additional Google searching (forhas me)so hasfar resulted in more of the same. Truthfully, the satire in Relativity Facepalm may be real.
