AG CORRECTION: Since each reference frame has its own spacetime labels, what's the justification f*or plotting a single object *moving wrt different frames on the same spacetime grid? AG I'm thinking of the Parking Paradox in SR, where the car is plotted from the pov of two frames, the car and garage frames, but the spacetime coordinates of these frames are* not *identical, yet the grid on which they plotted has only one set of coordinates. Something seems awry here. AG -- You received this message because you are subscribed to the Google Groups "Everything List" group.
