I would like to point out you left our conversation about a universal now after I answered
your point about how we are unable to view or see it. With God and without God the
universal now does change, with God it is as real as any period in time as a year or even
a thousand years, without God it is beyond seeing. So would universal morals would go
and change with and without God as well.
Well to be honest, it was difficult for me to think of a fruitful way of carrying it on. The classical physics picture has a fixed space and time as a parameter. In the trade this is known as a fibre bundle structure, the base space is time (a one dimensional line). At each point on the base space a three dimensional copy of the universe is in place, known as the typical fibre, the total space is the base space with fibres attached at each point on it. The laws of physics amount to rules about how the world line of particles has to be continuous when moving from fibre to fibre. With the advent of relativity this was replaced by a space-time structure, where there is no division into base space and fibres, the time dimension and space dimensions can be mixed in the same way that our familiar three dimensions are in a rotation. There is a four dimensional space which
locally looks like Minkowski space. Minkowski space is just the relativistic equivalent of Euclidean space - a flat four dimensional space with one dimension picked out as different and has a different rule to Pythagoras' one for distance (or interval or proper time as it is called in relativity theory). From the point of view of an entity outside the universe it is a static thing. To know what happened at some particular time, all such an entity would have to do is to look at the relevant part of our four dimensional universe. So I agree with what you were referring to as "universal now". It's just a little tricky as I cannot be sure that what you have in mind is what I do.
In philosophy there are roughly three views on space-time. The first is "Presentism". "Now" exists, the universe is three dimensional and neither the past or future exist. This is the framework of classical prerelativistic physics and is contrary to Einstein's theory of relativity. The second is "Eternalism", which is essentially the framework of general relativity. Your "eternal now" picture, provided it is from outside of the universe, fits this perfectly - there you are: Einstein's on your side. The picture I personally favour is called "Possibilism" in this the present and the past exist. Up until "now" it is the same as the "Eternalism" picture but it leaves the future open, it doesn't exist yet. There are some problems with this picture which are beyond the scope of this post (unless you want a really tough discussion), but relate to EPR type scenarios where different observers disagree about what the past and future are - I do not know if they are resolvable. However it also fits with Christian cosmologies as first it allows for free will, which I think is necessary for divine judgement to make sense in the first place, as well as making a final judgement make sense as by those times everything will have happened and so the whole history of the universe will be there for an omniscient judge.
So to sum up, I cannot see any logical or even nomological problem with your "eternal now" picture. Since I basically agreed with your first post on this matter I saw no particular reason to disagree with it. What I'm arguing with in this thread is the not the notion that Christianity is possible (I'll give you that, and an eternal now picture fits that) but the notion that a God is necessary for ideal justice, I'm arguing that we have no basis other than scripture and the other signs Christians normally claim that other cosmologies (in the sense of Heaven, Hell and "supernatural" entities) are impossible. So any claims about the necessity of God for absolute justice are nomological in the sense that one can imagine other mechanisms but it just happens to be that we have a God and that that God provides for an absolute justice, assuming that such a God exists to have these properties.
