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. * Not at all. You think it depends on acceleration. Fine, then here's an alternate version with acceleration. The twins each accelerates exactly the same level for exactly the same duration. * No. This is wrong and is the cause of the so-called paradox. AG* But Red is still younger than Blue for exactly the same reason; his path is longer in space and therefore shorter in spacetime. *But why do the paths have different lengths? Answer; one twin is accelerating, the other not. AG* *So, if there is acceleration, there is also gravity by applying the Equivalence Principle, * So did you apply gravitational time dilation to each twin above? *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, * Above you seem to think the equivalence principle means acceleration implies gravity Brent *so claiming I did so, shows you didn't understand my solution (using GR!).
