Apologies to long-time list members for re-iterating like a broken record...

I think when people speculate about other universes in the multiverse,
they continually fail to
grasp the likely extremely constrained nature of OBSERVABLE universes.
An observable
universe MUST be structured/defined so as to be capable of evolving
self-aware substructures
(SAS's) such as ourselves, in order for it to be in-principle
observable. I posit that these constraints
are EXTREMELY ONEROUS. No, this is not some naive anthropocentrism. I'm
working from
intuitions about emergent systems theory, and notions of the highly
constrained energy regimes
in which self-organization of systems can occur (At least,
self-organization of systems that have
properties likely to lead to coherent observer-systems.)

IT COULD BE that all alternative "people" MUST be seeing a universe very
similar to ours, or indeed
possibly EXACTLY ours, simply because otherwise their self-organization
break down in their universe, and they couldn't observe.

In other words, it COULD be that there is only one OBSERVABLE POSSIBLE
world. Now that's
an extreme, I admit, but I think it's closer to the truth than imagining
infinite numbers of really weird, unimaginable
observers in really weird, unimaginable alternative universes. The main
point is that the constraints required
to produce EMERGENT SYSTEMS that can be classified as what we think of
be, again EXTREMELY onerous, extremely possibility-constraining

There may be, in the imagination, other weirdo observers coming up with
a weirdo model of the universe, but maybe
some inconsistency in the notion of their existence (as complex, stable
systems in a complex yet stable habitat)
in their world means that they simply CAN'T exist.
