Nevertheless, if we can imagine that we can look into another FoR without having to become intimately involved in its FoR, we can certainly imagine that physical change does indeed take place, as far as each of the observers are concerned. If it is so that SR actually states, "nothing happens to a rod by being observed" as you describe that statement's relevance to this discussion, it is just as valid to claim that the physical changes are as real as our being able to look into another FoR without our own For becoming an additional factor of the other FoR. |
