All,I haven't made any progress getting the idea of a common universalpresent moment across so here's another approach with a thoughtexperiment....To start consider two observers standing next to each other. Do theyshare the same common present moment? Yes, of course. Anydisagreement?

`If they are *very* close to each other. Superposed, but not in the`

`quantum sense, but in the sense of being at the same place.`

Now consider those two observers, one in New York, one in SanFrancisco. Do they share the same common present moment? In otherwords is the one in San Fran doing something (doesn't matter what)at the exact same time the one in New is doing something? Yes, ofcourse they do share the same present moment. Any disagreement?

`That seems to introduce a notion of simultaneity incompatible with`

`special relativity. They share the same present *in* some referential,`

`but not in all.`

Now consider an observer on earth and an observer in some far awaygalaxy. But with the condition that they share the exact samerelativistic frame in the sense that there is zero relative motionand the gravities of their planets are exactly the same so thatclock time is passing at the exact same rate on both their clocks.Now are these two observers sharing the exact same present moment aswell? Note that we just extended the exact same relativisticcircumstances of the previous two examples so there can be norelativistic considerations. Do these two observers also share theexact same present moment as well? Yes, of course they do. Not onlydo they share the exact same present moment but they also share theexact same clock time t value. Any disagreement?OK, if you agree then you have to take a partial step towardsaccepting my thesis of a common universal present moment. You nowmust agree that there is at least a common universal present momentacross the universe for all observers in the same relativistic frame.Agreed?
