Twins Paradox

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

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

In fact, predicted responses to this Relativity Challenge are covered well.  On a humorous note, a summary of common assumptions are addressed in this satire.

Before Einstein's theories of relativity, a universal frame of reference was generally accepted.  The Lorentz Ether Theory (LET) continues to be a common alternate theory to relativity: The Twin Paradox in Special Relativity and in Lorentz Ether Theory
