Hi Stephen P. King
I saw a paper once on the possibility of the universe
inventing itself as it goes along. I forget the result
or why, but it had to do with the amount of information
in the universe, the amount needed to do such a calc,
etc. Is some limnit exceeded ?

Hi Quentin,
Yes, they are solved algorithmically. I am trying to get some focus
on the requirement of resources for computations to be said to be
solvable. This is my criticism of the Platonic treatment of computer
theory, it completely ignores these considerations. The Big Bang theory
(considered in classical terms) has a related problem in its stipulation
of initial conditions, just as the Pre-Established Harmony of Leibniz'
Monadology. Both require the prior existence of a solution to a NP-Hard
problem. We cannot consider the solution to be "accessible" prior to its
actual computation!
The calculation of the minimum action configuration of the universe
such that there is a universe that we observe now is in the state that
it is and such is consistent with our existence in it must be explained
either as being the result of some fortuitous accident or, as some
claim, some "intelligent design" or some process working in some
super-universe where our universe was somehow selected, if the prior
computation idea is true.
I am trying to find an alternative that does not require
computations to occur prior to the universe's existence! Several people,
such as Lee Smolin, Stuart Kaufmann and David Deutsch have advanced the
idea that the universe is, literally, computing its next state in an
ongoing fashion, so my conjecture is not new. The universe is computing
solutions to NP-Hard problems, but not in any Platonic sense.
