Bill, you seem to be saying that static time rules out evolution. If you are standing still, and time is flowing past you, any changes you make constitute evolution in time. Because motion is relative; it must also be true that if you are moving through static time you must be able to observe no differences in the outcomes of your actions. Your evolution in time is the same in both cases. What is there in GR calculations that would make this untrue?


I was referring to Orac's statement that time is a quite static thing in GR. I interpreted this to mean that GR calculations are made without regard to time. That would mean that time was not evolving, just passing. In GR time is a component of spacetime and therefore any changes in space also produce a change in time. As I understand it this is really the heart of GR, that there is no separation between time and space.
