Twins Paradox

The Twins Paradox is a famous thought experiment showing a confusing potential outcome of time dilation predicted by Special Relativity.

Are any answers by academics in the threads below (one referencing the other) satisfactory explanations of the Twins Paradox? You be the judge.  To me, these thoughtful answers bring up more new questions than are answered; a tell-tail sign something isn't quite right.

In fact, many predicted responses listed in this Relativity Challenge are well covered.  On a humorous side, a summary of common responses are also addressed in this satire.

Before Einstein's theories of relativity, a universal frame of reference or, commonly known as aether, was generally accepted.  The Lorentz Ether Theory (LET) continues to be a common alternate theory to relativity.  Incidentally, LET does not havecontain a Twins Paradox.
