The idea of a measure that Bruno talks about is just another way

performed to "find" it.
Because UDA+MGA shows that even if a "real" primary physical universe
exists, it cannot explain anything related to what I can feel to
observe from my 1p view.
Obviously, the appearance of a universe makes it natural to believe
that a simple explanation is that such a universe exists, but this has
been shown to not work at all, once we assume we are Turing emulable.
So f you are right, then there must be flaw in UDA+MGA, but each time
we ask you to point where it is, you come up with philosophical reason
to discard comp (without always saying it).
I do not blame him as this problem has been glossed over for hundred
of years in math and thus we have to play with nonsense like the
Axiom of Choice (or Zorn's Lemma) to "prove" that a solution exists,
never-mind trying to actually find the solution. This so called
'proof" come at a very steep price, it allows for all kinds of
paradox.
This is unclear. Comp is axiom-of-choice independent. Even
arithmetical truth is entirely axiom of choice independent. ZF and ZF
+ AC proves exactly the same arithmetical truth.
A possible solution to this problem, proposed by many even back
as far as Heraclitus, is to avoid the requirement of a solution at
the beginning. Just let the universe compute its least action
configuration as it evolves in time,
This does not work, unless you define the physical reality by
arithmetic, but this would be confusing. It seems clearer and cleare
that your "existence" axiom is the postulate that there is a physical
primary reality. But then comp is wrong.
At least Craig is coherent on this. he want some primitive matter, and
he abandons comp. His theory is still unclear, but the overall shape
make sense, despite it explains nothing (given that he assume also a
primitive sense, and a primitive symmetry).
Bruno
but to accept this possibility we have to overturn many preciously
held, but wrong, ideas and replace them with better ideas.
Onward!
