Amen on most points, Edgar. I also have misgivings about the existence of the multiverse for different reasons that this posting is not the place to vent.

But, for we humans, the present moment exists for each of us. Your "common present moment" is an assumption that all x, y, and z of this 3-D realm experience simultaneity, even though every local set of coordinates, for instance, x1, y1, z1, if they have a self-aware structure (SAS), i.e. an observer, will have different experiences - albeit, even if only that the coordinates are different. You are trying to make your "common present moment" an axiom of reality that, for all x, y, and z, there is only one t. Though it makes common sense for a strictly Newtonian universe, when one adds relativistic considerations of the connectivity of space and time into a space-time continuum, your axiom of a common present may not hold.

I am, BTW, a physicist by education. I don't post much.

Certainly, your assumption can be made and explored.

To answer some of Jason's questions. Block time is wrong. Only the common present moment exists. All the comments Jason makes refer only to differences in clock times which are well known, but the important point is that all those differences in clock time occur in the SAME common present moment.. I find it difficult to understand why so many people can't get their minds around the difference which proves there are two distinct kinds of time.

The past exists only as inferences from the present as to what states would have resulted in the present according to the currently known laws of physics. Therefore the past is actually determined by the present state of reality from the perspective of the present which is the only valid perspective. Therefore the logical network of past and present is absolute 100% exact and could not have been different in even the slightest detail. The actual currently state of the universe falsifies the very possibility of other pasts. This is another difficult concept for many. 

Only the future is probabilistic because it does not yet exist and has never been computed. But the past - present logical state has been actually computed and thus is completely deterministic now that it exists and it could not have been different in any minute detail at all.

This solves the problem of the original fine tuning. Given the current state of reality which is all that exists, all other conceivable fine tunings are impossible. This is what I call the 'Super Anthropic Principle', and it negates the necessity and probably the actuality of postulating any multiverses and strongly implies our observable universe is most probably the only one that exists.
