Hypnagogue: I am sorry but I am called upon to disagree with you. Here is a description of our universe that is simple and answers the above questions. You may think of this as and extension of Newtonian if you wish. It shows SR and GR to be only a small part of all things. If you disagree please be specific and don’t just make a comment that it does not agree with some other theory. Observation indicates that the universe started with the Big Bang and that all that is the universe transitioned outward from the Big Bang and is now a distance from the Big Bang. Having no evidence of reason or observation it is expected that all that is the universe is at an equal distance form the Big Bang in all directions. Thus forming a type of hollow sphere. The rate of transition outward from the Big Bang having no known limit other than the speed of light can be assumed to be at a rate equal to the speed of light. At this point we are able to touch again on observation and we find that this transition outward from the Big Bang meets all the tests and qualifications of what we recognize as time. Therefore a reasonable result is that the transition of the universe outward from the BB is a transition in the time dimension. We are able to come to the conclusion that there is an absolute time, the distance outward from the BB, and that this time is the same for the whole universe. All actions therefore are always in the present throughout the whole universe. The above being the case there is no prohibition against instantaneous information transfer, as you can never arrive before an event. You now have an observational viewpoint that does not contradict any known theory or observation. It may contradict the interpretation of some theories but not the basic theory.
