The clock at point 'A' should show 'A-time', which is the local time at point A. Same with point B and 'B-time'. But those time measures are local to A and B (and do not necessary run into the same direction at all possible points). That remote location uses the same time, which runs into the same direction and makes clocks tick at the same rate, that is an assumption. But this assumption also means, that all clocks in all the universe would run into the same direction and make clocks tick at the same rate. THAT is actually 'Newton's absolute time', which is 'external' (kind of 'God's clock'). But if time isn't external, then time had to be restricted to the location in question. This would allow the observer at point 'A' (for instance) to declare himself to be at rest and everything else as moving. But that observer would need to consider, that all other observers could do the same, but with other time-measures. > >> The use of Euclidean space in SRT defines also time as absolute measure. >> >> this is so because Euclidean space is meant as 'timeless'. > > Why does the fact that there is no 'time' in the metric > ds² = dx² + dY² + dz² imply that the time Δt is 'absolute'? Not delta(t), of course, but time t itself. Without some 'absolute time t' you could hardly use delta(t), because that wouldn't make sense, if you have no time t to beginn with. > What does it mean that the time Δt is defined "as absolute measure"? >> >> This 'timeless' means, that time and geometry are treated as >> fundamentally distict entities. > > Of course time and space are fundamentally distinct entities. Not just because you say so! I wanted to show, that a spacetime diagram could be treated as complex valued plain. Then time would become imaginary and the real axes real. Now we could take the axis of time and rotate it (in our mind only, of course). Then another axis would become the new axis of time with new orthogonal real axes of a space, which is also filled with new matter. Even if the concept is mathematically very simple, it is totally counter-intuitive. BUT: the real world we live in looks like precisely following such a principle. In case you don't understand the idea, you could read my 'book', which can be found here: https://docs.google.com/presentation/d/1Ur3_giuk2l439fxUa8QHX4wTDxBEaM6lOlgVUa0cFU4/edit?usp=sharing ... TH
