Objective truth in multiple universes

If we accept the existence of multiple universes, and adopt a criterion of transworld identity such that our existence is not necessarily confined to one single universe but rather spread out across all the many existent universes in which we are identical (at least in some temporal part), then it could follow that certain statements might be true in some universes and false in others, and yet all those universes being equally this universe for me, then for me they would be equally true and false. Whereas for others, who only exist in some of the universes in which I exist, those very same statements might be entirely true or entirely false. However, we can eliminate this issue by rewriting all statements from X to “X in every universe U”, where U is some phrase which identifies universes. Then, those rewritten forms of the original statement are no longer capable of being simultaneously true and false in the way that the original statement was. And yet, every ordinary statement we make, is not in the form “in every universe U”, but rather in the form “in some universe that I exist in”.

A criterion of transworld identity which identifies persons across universes takes away the boundaries between universes. And I think, with Q-space, we can dispose of the boundaries entirely. The claim that you and I are identical in some temporal part, is simply the claim that within that temporal region we wholly overlap in Q-space. The claim that you and I, while being non-identical, both exist in the same universe, is simply a claim about the geometrical similarity of the Q-space regions we occupy. Thus, once we introduce Q-space, we can dispense with parallel universes (a bit like Schopenhauer’s proverbial hired cab).

I have previously thought that the true model of the universe consists of these components: qualia; minds; relationships between qualia and minds; relationships between qualia; relationships between minds. The first relationship is that of binding; the second relationship is the geometry of Q-space; I’m starting to think the third relationship is a relationship of geometrical similarity between bound Q-space regions (Some days, I will add universals to the mix; other days, I’m not so sure if they exist.)
