Ok. Here's the thing though: Observables: There's one Universe.
Any notion of more than one is based upon the mathematics. This
does not negate the validity of the mathematics for mathematics
sake but multiple Universes is a mathematical notion being
applied as a possibility for reality WITHOUT a corresponding
observation. This doesn't mean that it "might not be true". Of
course it might be. But it's fictional. At present, it's
fictional. This doesn't mean that it's not a good idea to pursue
it. Someone just did a preliminary test on parts of the
holographic Universe for example, which is a mathematical model
and found no evidence as of yet. [I can find link but I'm
guessing you've seen it. I can find it of course] Again, doesn't
invalidate it. But there is a danger of analogies here:
Mathematics is an analogy. It's a GREAT analogy. But it's
analogy. There's also a strong belief system in place here: The
grand unification of the Sciences with mathematics as its basis.
That's not to say that it might not be true: it _might be_. But
at present, it's not true. The gaps are wide between the
Sciences. Perhaps they will be bridged one day. I hope they are.
But to say "they are" is a belief... and a hope but currently a
fiction. It's a good fiction, but it's a fiction.
