Dear Bruno,
Why do you not consider an isomorphism between the Category of
computer/universal-numbers and physical realities? That way we can
avoid a lot of problems!
I think that it is because of your insistence of the Platonic
view that the material/physical realm is somehow lesser in
ontological status and the assumption that a timeless totality =
the appearance of change (and its measures) is illusory. I would
like to be wrong in this presumption!
The problem is that assuming the material / physical realm as
fundamental gets you no further than assuming that "God did it!"
It's a "shut up and calculate" (or shut up and pray) ontology.
With materialism you just have a "brute fact" - well, maybe that's
it, maybe there is just a brute, unexplained fact. But us ape
descended life forms like to look for explanations even beneath the
apparent brute facts!
But "Everything happens" is just as useless as "God did it". A
theory that can explain anything fails to explain at all.
It can't explain anything. It just says that all outcomes of the
laws of physics are instantiated.
But that is already a physicalist idea of everything. It assumes
physical laws, and it assumes "things" satisfying physical laws. And
it assumes often, like in tegmark, some identity between knowledge and
brain states (which might violate the constraints of comp).
Everything and nothing does not mean anything if "thing" is not
defined, and this needs to assume *some* thing(s).
This requires less information than saying that a specific outcome
of the LOP is instantiated, assuming the LOP allow more than one
outcome.
But I feel that you must already know this. Are you just being
Devil's Advocate, or do you honestly not see the usefulness of
multiverse theories?
It is not that they are useful, but we cannot escape them (with comp
or weakening, or just with QM). And they do not explain, they lead to
problem that we must solve.
Bruno
