Brent But if garage frame spacetime coordinates x, t, and car frame has spacetime coordinates x', t', and the plot represents the situation from the pov of garage frame, how can the car be plotted using x, t, when those coordinates aren't its spacetime coordinates? AG The primed and unprimed coordinates of a given point are related by the Lorentz transformation, (t,x) and (t',x') are the same point just plotted in different coordinates. Brent I think I get it. In your first plot, you're describing the situation from the pov of the garage frame, so the plot coordinates are x,t, whereas in the second plot you're describing the situation from the pov of the car frame, so technically the axes should be labeled x',t' (but you left them as x,t), AG -- You received this message because you are subscribed to the Google Groups "Everything List" group.
