        I agree, but I am thinking of the nature of these space-times that are
superposed. Are they a priori definite or are they even categorizable as
space-times? Could you explain your take on the philosophical problems
implied by my hypothesis? I am very happy for a critique on this notion!

        Yes, each observation involves only finite amounts of information and
the content changes in every moment of conscious! How this changes and
what are the trade-offs is important. The statement "consistency implies
existence" is a two edged sword! We must understand that given finite
information only a lower bound can be placed on the internal consistensy
of observables. Reality, for me, is the Totality and it is, as a whole,
unknowable, e.g. it is impossible to map an infinite set onto a finite
set in a unique manner. Or am I wrong on that? :)

        Yes! :) Communication acts are mappings from one space-time to another,
if we follow Edelman's line of thinking in "Bright Air, Brilliant Fire"
so your notion are accurate. I am trying to understand consciousness as
a quantum-like action and can be composed to for different sized units.
The information content can vary within the uncertainty trade-offs so it
is not an atom in the classical sense. The closest I have seen this idea
discussed is in Pratt's papers. I wil try to write up this more.
        The key understanding needed is that observations involve computation
of the involved minima. Such are not "free"! The computation of the
Lagrangian of a system has a price tag in free energy available to an
observer. When we think about the computations involve in the traveling
saleman problem we see clear example of this notion.
