He said "compared to coordinate time", which is completely correct.Vandam said:The way you explain it is as if the time dilation occurs due to the further dots pacing of clockticks on the clock worldline.
No, his statement is still correct. The black dots are the most closely spaced "compared to coordinate time" for black. The blue dots are further spaced and the red dots even further. "Compared to coordinate time" measures only distance normal to the lines of simultaneity, what you have labeled "spaceworld".Vandam said:Here you see clearly that the 'slowing down' of the blue and red clock have NOTHING to with the further spacing of blue or red dots relative to the black dots (red dots are equally spaced as black, blue dots are less spaced relative to the black ones!).
This is also true, but doesn't make ghwellsjr's statements wrong. The relativity of simultaneity is what changes the meaning of "compared to coordinate time" for the different frames.Vandam said:On a Loedel diagram (I'm now too lazy too make one) you would see that the time dilation has nothing to do with the further spacing of clock ticks on the worldline of a clock. Time dilation is about relativity of simultaneity.
