Hi Andrew,
The answer to the simple question that you see that all of this
detail leads to is that at its core, Existence is Change itself.
Becoming is the fundamental ontological primitive., just as Bergson
argued. This is the result that Hitoshi discovered and discussed in
his Inconsistent Universe Paper in terms of the truth value of the
total Universe being in an infinite oscillation between True and
False. Bart Kosko also obtained a similar result in how research on
Fuzzy sets. What Barbour really found is that there does not
exist a universal */global /*standard of measure of this change.
I think Einstein found that long before Barbour. There's no time-like
Killing vector field in an FRW universe, so there's no universal time.
If there is no standard then there is not a determination of
definiteness for the Total Change of existence and thus there is no
global measure of change. Since time can be defined in generic terms
as a measure of change, Barbour is correct in claiming that time as a
global quantity cannot exist.
What Barbour missed, as have countless others, is that/*local
measures of change can be defined*/. The fact that there is more than
one measure of entropy is a huge clue of this.
Thermodynamic entropy has always been relative to whatever is taken to
be the constraint (constant energy, constant pressure,...) In the
Everett interpretation evolution is always unitary and the Boltzmann
entropy is constant.
Yes but! Thermodynamic entropy is a predictable process in the 4D
reality, as is unitary evolution. But change of the state, the
appearance of collapse, is necessarily a process 'outside' of the
unitary evolution. One has to be outside of the 4D reality in order for
one's field of observation to sweep through the 4D reality, just as one
has to be outside of the computer screen to run one's eye across the
text displayed on it. But, as I see it, the logic is even more
compelling in the case of the change from state to state.
