I have some questions related to Wheeler's ideas of "It from bit" and "Law without law"

In summary, these both theories postulate that there was an initial universe with no laws from which laws of physics appeared from informational processes (It from bit)

  1. In a book ("The Hidden Pattern" by Ben Goertzel) it is said "John Archibald Wheeler's (1988) idea of “law without law” and “it from bit” —which hypothesizes that the laws of our physical universe are in some sense optimal, so that if someone has an objective or physical world with unformed, indefinite laws, the laws will eventually settle into the optimal law configuration (being the laws of our universe)"

    • Assuming Wheeler was right and According to Wheeler's "it from bit" and "law without law", could the optimal laws have been different? If I understand these theories correctly, the initial universe did not have any laws/rules and the laws were created by the informational processes of "it from bit". Because of this, could these informational processes have created different rules/processes that would give as a result a different universe with different laws? I mean, could the initial lawless/ruleless-universe have evolved differently, giving as a result a different universe with different laws (not only our own set of laws)? Arbitrarily different?
  2. Since the initial universe did not have any rules, could "it from bit" have created radically different truly fundamental laws and rules? Could it have created a different universe behaving even according to fundamentally different types of mathematics/logic? Could it have created a universe with fundamentally different computability/information theory? Could it have created a universe where uncomputable or even illogical/logically impossible/indescribable/nonexistent/impossible things could be computed? Since the initial universe would not have any rules, would it from bit be adjusted to computability and information theory? Or would computability/information theory not exist in the initial universe, and because of that, "it from bit" could do things outside of them (could do things forbidden by them)? Would the same happen with logic (Did the initial universe behave according to some type of mathematics/logic or they did not exist at the initial universe)?

  3. If the above would be right and the universe could have behaved according to radically/fundamentally different laws/maths/logic, could "it from bit" processes have created a universe behaving according to paraconsistent logic ( https://en.wikipedia.org/wiki/Paraconsistent_logic) or a trivialism (a system where every statement/"thing" would be true and false at the same time: https://en.wikipedia.org/wiki/Trivialism, it could be called an illogical system)? (the consequences of both systems would be uncomputable, but if it from bit created computability and information theory, could they have created a different computability or information theory where they would be computable?) Or, since things in it from bit would derive their existence from solely informational processes, and since the definition of a trivialist/paraconsistent system is a computable definition (otherwise we could not define them), could an it from bit-informational process computing just the solely definition of these systems be enough for these systems to exist? In summary: Could "it from bit" make trivialist/paraconsistent systems exist in a universe?

  4. If the above is right, wouldn't that mean that Wheeler's law without law and it from bit would be an unfalsifiable theory? (Since they could produce all types of universes/outcomes, even impossible/uncomputable/logically impossible/illogical ones.) Also, would they be a multiverse theory? (besides being capable of creating different versions of a given universe, could they create multiple universes at once?)

(I need answers from people that know well these theories. Although this is relate with philosophy, that's why I put this question here, I need answers mostly based on a scientific point of view not only/purely philosophical)

    1. Yes; 2. Yes; 3. Meaningless question, logic is not on a par with causal laws. It is a property of descriptive language, not what it describes. We can choose paraconsistent logic to describe even this universe; 4. No. That evolution can produce all kinds of organisms does not mean that it can not be tested as a theory, it is the same with universes. Formation processes can be substantiated indirectly (traces, simulations, etc.). – Conifold Dec 3 '18 at 23:31
  • @Conifold In the question #3 I meant whether the universe could have laws that actually behaves according to the types of logic ("illogical logic" in the case of trivialism) I described. It's true that logic is independently from reality, but nature behaves according to a given type of logic (can be described by it). I was asking whether there could be universes whose nature could be described by these logics (and trivialism) in Wheeler's theories/ideas. – physistack Dec 4 '18 at 21:55
  • @Conifold Also, although we could use these logics (and trivialism) to describe our universe, it is not obvious that they are good to describe our nature (in fact trivialism is generally rejected) and we could be wrong/mistaken trying to use them to describe the universe (it could be the case that the nature of the universe does only actually follow classical logic). So I was actually asking whether there could be universes in Wheeler's theories/ideas (law without law and it from bit) that could have nature ACTUALLY following these logics – physistack Dec 4 '18 at 21:56
  • @Conifold (or "illogic logics" as in the case of trivialism and the different types of trivialism that exist). Also, referring to #4, if Wheeler's ideas/theories could then indeed produce all universes (even illogical/logically impossible/impossible/nonexistent universes or universes without any logic/rules), there could be the case that the processes based on Wheeler's ideas/theories could be "hided" or even deleted (since Wheeler's ideas/theories could produce literally ALL outcomes, even impossible ones). – physistack Dec 4 '18 at 21:57
  • @Conifold So if that would be the case and we lived in such universe, there could be the case that we could not know whether it was based on Wheeler's ideas/theories. Finally I would also like to ask: It is said, for example, that "it from bit" would be a discrete informational process that would create universes. But if Wheeler's ideas/theories of law without law and it from bit could produce literally ALL outcomes (even impossible ones), there could be the case that the "standard" form of "it from bit" would change into anything else, right? – physistack Dec 4 '18 at 21:57
