But he's an ignorant troll and won't admit it even when it is so clearly pointed out (some of it can 'work' for 2 bodies, but put in a third and it falls apart).

Please explain Relativity along with everyone else. Mitch Raemsch

(Yes, that's possible.) No....this is not possible. Why? Because the passage of an A second does not correspond to the passage of a B second and the passage of a C second. Each observer must make his won determination using his clock second to determine velocity and the gamma factor. In other words you can't compare gamma factor between frames. A would predict B's rate as follows: T_b=T_a/gamma_ab OR T_b=(gamma_ab)T_a A would predict C's rate as follows: T_c=T_a/gamma_ac OR T_c=Gamma_ac(T_ac) What this mean is that each observer must use his own clock second to determine the rate of an observed clock. > > From your theory the below observations should all be true: > Observer A would measure: > (1) tB=tA*gamma or (2) tB=tA/gamma > (3) tC=tA*gamma or (4) tC=tA/gamma > Observer B would measure: > (5) tC=tB*gamma or (6) tC=tB/gamma > > Now, if (1) and (3) are true that means tB=tC, which contradicts both > (5) and (6); observers A and B would disagree on their observations. > If we take (1) and (4) as true then tB=tC*gamma^2, which contradicts > both (5) and (6); observers A and B would disagree on their > observations. > The same goes for the other combinations.

I included that comment in anticipation of your objection. Ken, relative velocity is mutual, v_ab=v_ba, regardless of the length of ones second. Why? Because velocity is distance/time, and both distance and time vary by the same factor. If one measures longer time he also measures longer distance; the ratio stays the same, right? And yes, you can have 3 observers moving at the same relative velocity, v_ab=v_ac=v_bc and therefore the same gamma; gamma_ab= gamma_ac= gamma_bc. Gamma is a function of only the relative velocity. In fact, in 3 spatial dimensions, you can have 4 observers moving at the same relative velocity. Try harder!

No....In that case you can't compare Tc as predicted by A with Tc as predicted by B. Even if you assume that A, B and C measure the same velocity.... A predicts the following for Tc and Tb: Tc<Ta OR Tc>Ta Tb<Ta OR Tb>Ta This means that you can't assume that Tc=Tb. This means that your assumed contradiction based on what B predicts for Tc is not valid. In any case how does your gedanken support SR? SR predicts from A's point of view: Tc=Ta/gamma Tb=Ta/gamma Therefore Tc=Tb From B's point of view: Tc=Tb/gamma This means that Tc=/=Tb This means that B's point of view is directly contradicting A's point of view.
