jartsa said:An inertial observer might say that the observer in the accelerating rocket gets fooled into thinking that the clock at the front of the rocket is going faster than the clock at the rear of the rocket by the way that light travels between the rear and the front.
So this is very "relative".If in an accelerating rocket a clock is moved next to another clock, then everyone must agree about the rate difference and the difference of the readings of the two clocks. So now the inertial observer must agree with the observer inside the rocket. So the two observers must agree that a front clock has ticked faster than a former rear clock that was at some time moved from the rear to the front.
So this is "absolute".
So the truth of the situation would not be relative, the inertial observer would have initially been wrong.
