You still don't understand what I'm trying to tell you (it's been four decades). We breathe, we blow. We have a little coffee, and we hold our heads in our hands. WE CANNOT absolutely synchronize two watches with each other, because it is physically impossible. This is like saying: "draw me a round square". We must therefore synchronize the two watches on a third virtual watch for which the two events watch A marks noon, and watch B marks noon are SIMULTANEOUS. It is on the universal simultaneity of this abstract watch that physicists build their usable universe. This watch does not exist, it is virtual, although very useful. I repeat it again and again, watches A and B cannot be tuned to each other. If I agree A on B (I say that the two events A1 and B1 are simultaneous) for A, but they will no longer be for B. And so on for the entire universe. A synchronization of type M is then necessary, and we imagine, without realizing it, a point M placed very far away in a hypothetical fourth dimension and at an equal distance from all points A, B, C, D, etc... of the universe. This point M has its own hyperplane of present time, in which all events take place at the same instants and we note tM(e1)= tM(e2)=tM(e3)=etc... And it is on this virtual point that we refer when synchronizing all the watches. Synchronizing the watches (let's breathe, let's blow) does not mean "agreeing to say that all the watches mark noon at the same time", it is grotesque, false, and absurd. This is NOT what it means. Believing this is an idea as religious as it is false. It simply means that for M, all events occurred at the same present moment. I repeat it again because it is so important, and because it is the very basis of the theory of relativity well understood: It simply means that for M, all events occurred at the same present moment. Paul, Paul, I beg you to understand this concept which, I know unfortunately confuses 99.9% of those who read me. Paul, Paul, I beg you to make an effort to understand, and to UNDERSTAND the simple notion of universal anosochrony and the usefulness of this abstract virtual watch that the whole world uses without understanding that it is a useful watch, but virtual and that NEVER two events can be RECIPROCALLY SIMULTANEOUS. It is only by abstract convention that we use the notion of synchronized watches. If you understand French, you will see that I write in my pdf: "Just as all consciousness is consciousness of something, all synchronization is ========== REMAINDER OF ARTICLE TRUNCATED ==========
