Question:
Assume the the while universe can be described by a quantum theory.ie. there
exists a wave function for the universe. There have been a number of proposals
for the quantum boundary conditions for this wavefunction at the begining of
the universe. If one of these boundary conditions succeed in specifiying
a unique wavefunction what does this say concerning the uncertainty in the
evolution of the everyday classical world and free will? Frequently the 
wavefunction of the universe is called on to calculate the characteristics
of large structures ie. inflation, density perturbations etc. However,
in principle, how far can the information content of this wavefunction reach?
Can it (is it suposed to?) describe the milk mixing in my tea? The standard
probabalistic interpretation of QM is not clear here as we are attempting to
describe the one universe by a single wavefunction and attempting to make
predictions. Or is the Many-world description more appropriate? To put my
question another way.. do the correlations contained in the quantum 
cosmological boundary conditions contain all the information necessary to
describe the complete future of the `classical' world deterministically?
