Not unique.

E.g., consider a set L={1,2,3}. (In the case of the universe, L may be an

infinite set. At this point, to use the notion "cluster decomposition" b

concerning the universe may be an abuse at least at the present stage of the

theory. This point might be related with Obler's paradox as I mention below.)

Then the set Q is

Q={ {{1},{2},{3}},

{{1},{2,3}}, {{1,2},{3}}, {{1,3},{2}},

{{1,2,3}} },

consisting of 5 elements. b varies over those elements.

b={{1},{2},{3}} is the I-It case (completely classical). The observer sees each

particle as behaving classically.

q={{1,2,3}} is the I-Thou case. The observer sees L as a QM system consisting

of the particles 1,2,3 with some Hamiltonian like

H = -\Delta_{123}/2 + \sum V_{ij}(x_{ij})

with x_{ij} denoting the relative position between the particles i and j.

Other cases like q = {{1,2},{3}} are partially classical as well as QM case. In

this case, the particles 1 and 2 inside a cluster {1,2} behave as QM particles

with respect to the Hamiltonian of the subsystem consisting of the two particles

1 and 2:

H_{12}= - \Delta_{12}/2 + V_{12}(x_{12}),

while the particle 3 behaves like a classical particle that interacts

classically with the center of mass (CM) of the subsystem {1,2} consisting of 1

and 2. The Hamiltonian which might explain this QM-Classical system is given by

formula (QMG) on page 21 of time_IV.ps, which, however, is a quite rough

approximation.

On Obler's paradox and Big Bang, my rude idea might be that humans and their

apparatuses cannot see the universe U in completely QM way (i.e. b={ U }),

probably because the universe consists of an infinite number of particles. If

so, they have to see the universe in classical way to some high extent always,

then what they see should look like what we observe, i.e. the observation by

humans and their apparatuses tells us the universe is expanding and thus Obler's

paradox is not observed, even if the total universe might be stationary.

Assumption behind this is that as the number of particles of a system L becomes

larger, it would be more and more difficult to see L as a QM one, by some

reasons related with recognition (or computation in your context).

Best wishes,

Hitoshi
