A complicated explanation of the triplet paradox. Length contraction is consistent, but it's not necessary to understand the effect. AG will reject it because he doesn't "believe in" handing off clock readings. Brent *No, that's not it. Rather, I am uncomfortable with de-facto frame-jumping because I am unsure what happens to time when this is included in a solution. And if the twins are at rest and juxtaposed as the scenario begins -- which, BTW, is how the TP is habitually DEFINED -- the traveling twin MUST accelerate to begin his journey. But in the final analysis it's "your way or the highway", meaning that alternate solutions are unacceptable for you. So, if there is acceleration, there is also gravity by applying the Equivalence Principle, and clocks in gravitational fields slow down, and this applies solely to the traveling twin. Notice, I never used or applied the concept of force, so claiming I did so, shows you didn't understand my solution (using GR!).
