And you laughing with delight... or is it ignorance?

No, temporal order is observer dependent. JT, order of event is observer dependent and nicely presented in the 30-minute episode of the Mechanical Universe you can watch on your computer! The Mechanical Universe series. http://www.learner.org/resources/series42.html 42. The Lorentz Transformation If the speed of light is to be the same for all observers, then the length of a meter stick, or the rate of a ticking clock, depends on who measures it. Lesson 42: The Lorentz Transformation If the speed of light is to be the same for all inertial observers (as indicated by the Michelson-Morley experiment) the equations for time and space are not difficult to find. But what do they mean? They mean that the length of a meter stick, or the rate of ticking of a clock depends on who measure it. Text Assignment: Chapter 46 Instructional Objectives Be able to use the Lorentz Transformation to work problems relating time or space intervals in different reference frames. Be able to give some of the hypothetical explanations put forward to account for the Michelson-Morley experiment. Be able to discuss the concept of length contraction. Be able to understand and use spacetime diagrams. Be able to define and discuss the concept of simultaneity. Be able to define and discuss clock synchronization.

Their states of motion are identical, not different. Different gravitational potential means different states of absolute motion. That's why Pound and Rebka found frequency shift in the vertical direction.

Now you reply: "No temporal order is absolute in the macro cosmos realm, it is very easy to prove in a simulation." Whatever that sentence was supposed to mean (if anything), it appears that you are trolling - so I won't fall for that again. Goodbye, Harald Harald
