A light-clock is just two perfect mirrors a fixed distance apart with a photon bouncing back an forth between them. It's a hypothetical ideal clock for which the effect of motion is easily visualized.

TY, AG* *You can't handle more than two? The left clock is black with a red photon. Is that hard to comprehend? Didn't they teach spacetime diagrams at your kindergarten? Brent * *If you could cease behaving like an arrogant a'hole, likely beyond your maturity and capability, maybe we could get somewhere on this problem. I was thinking about your diagrams, and concluded you could prove your point with the simple observation and simpler diagram, that with your photon clock, it would be easy to show that from the pov of a rest clock, the moving clock would appear to have a slower rate. And since inertial frames are equivalent in SR, the same result would be evident for the rest frame, when considered as the moving frame. BUT, what I have shown, with an arbitrary clock, that all clocks in both frames can be synchronized, ostensibly showing the absence (sp) of time dilation. AG* *If you've shown it, where's your diagram? Brent* *"We don't need no stinkin' badges." -- a famous line from a great movie. I showed that all clocks in both frames can be sychronized, so that establishes (IMO), or at least strongly suggests, that there is no time dilation. Why would it exist if all clocks in both frames are in synch, and since they're identical, they tick at the same rate? AG* Because the speed of light is invariant the photon paths are at unit slope inside all three clocks, so it is easily seen why the relative motion makes the clock seem slow although each clock is ticking at the same rate in it's own reference frame. The red diagram is just the blue diagram Lorentz transformed as it would be seen in a frame moving the left at 0.5c, and the black diagram as it would be seen from a frame moving to the right.
