Discussion Overview

The discussion revolves around the concept of complexity in the universe and whether it emerges from simpler systems or if larger systems could be components of smaller systems. It touches on themes from cosmology and quantum mechanics, exploring the nature of reality and the relationship between large and small scales of existence.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant proposes that if complexity is emergent, then the universe as a whole might be simpler than its components, suggesting a reversal of the typical view where complexity arises from simplicity.
  • Another participant asserts that quantum theory serves as the simple structure from which complexity emerges, emphasizing the linear nature of the time evolution operator in quantum mechanics.
  • A third participant introduces a logical critique regarding the validity of general statements derived from specific examples, questioning the soundness of drawing universal conclusions from singular cases.
  • A later reply reiterates the idea that quantum mechanics is fundamentally simple but acknowledges potential fallacies in its application to larger structures, particularly concerning gravity.
  • This participant also questions whether it is logically coherent to consider larger systems as components of smaller ones, and what might prohibit the quantum world from being an emergent aspect of a larger universe.

Areas of Agreement / Disagreement

Participants express differing views on the relationship between complexity and simplicity, with some supporting the idea that complexity emerges from simpler systems while others challenge this notion. The discussion remains unresolved, with multiple competing perspectives presented.

Contextual Notes

Participants highlight potential logical fallacies and the need for clarity in assumptions regarding the relationship between large and small systems. There are unresolved questions about the mechanisms of gravity and the nature of quantum reality.

While discussing cosmology and quantum mechanics with a colleague, a strange idea began to emerge in our collective argument, and I was wondering if someone here could comment on the plausibility of this argument.

The argument goes as follows, if we establish as an absolute truth that complexity is emergent, the idea that complex systems can only naturally emerge out of simpler systems, if we treat this idea as a raw absolute, when we consider the fabric of reality as a whole what we perceive (from our limited perspective), is that the world of the very large, the entire universe as a single unit, is a much simpler construct than the components "within", complexity then appears to be emergent, we have small complexity when we treat the larger universe as a single unit and has a tendency into higher complexity in direct proportionality with smaller scales.

My question is then, is it plausible to assume that rather than being the quantum reality that produces the larger universe, couldn't it be in fact the opposite?

Has anyone proposed this as a theory before, and if so, can I read more about it?

Is this theory disprovable by something I'm failing to consider?

Thanks

Quantum theory IS the simple structure from which complexity emerges. The very basic assumption of QM is that time evolution operator is linear. You cannot get simpler than that.
 
From strictly a LOGIC standpoint - if one offers a Specific example then goes on to provide a UNIVERSAL statement drawn from this example, the whole statement fails if you have ONE example that refutes the specific statement ( example - i have a cat, my cat has fleas, therefore all cats have fleas) refuted by one person having a cat that does not nor ever has had fleas. Now compare the general to specific ( all automobiles have four wheels, I own an automobile, therefore my automobile has four wheels...)

Yes, but there are still fallacies within quantum mechanics and/or it's correlation with large scale structure such as the exact mechanism from which gravity emerges and what it actually is.

I have basically two questions.

First, in abstraction, is there any logical fallacy in the assumption that instead of big systems being produced by simpler ones, it could in fact be that big systems are in fact the components of smaller systems?

If the answer to the first question is illogical, please ignore the following question.

Second, considering that the first assumption is logically coherent, what specifically prohibits the quantum world of being an emergent aspect of the larger universe?
