I agree this is the sort of ontology we should look for, which is one reason I find comp attractive even if I don't follow it all (but Bruno has promised to give more lessons!) > >>>> That is all correct, The point is that there is no prefered foliation, >>>> no special narrative for all the events. >>>> >>> Yes indeed. Hence "relativity" ! But space-time itself is (within SR) is preferred (so to speak). That is, there is one block universe, within SR, in which (I believe) each point can be uniquely labelled. > >>>> I thought momentum was space's cc, and energy was time's???
