You don't need to imagine the whole boundless universe. You need to imagine a bounded universe. That is logically impossible unless the universe is bounded by something else, let's call it B. B however is either unbound or bounded. The whole system is unbound if B is unbound. We however have the same problem if B is bounded because it has to be bounded with something else. Etc.
Then you can never address model incompleteness. If the universe is unbounded, but my imagination is bounded I am necessarily leaving parts out.
There are 10^125 particles in the observable universe (estimated).
∞ - 10^125 = ∞
Probability theory doesn't work with infinities.
And you also contradict yourself. If you are imagining a bounded universe, then you aren't trying to understand the unbounded whole. You are trying to understand part of the whole. Which part?
The distinction between closed and open systems in systems theory is huuuuge...

The theory of everything is about how elementary particles behaves. We however have problem to find exact wave function of a system which has many particles. We were able to develop different methods to deal with this problem if the system allows us. This area of study is called condensed matter physics.
Yes. And from having complete understanding of how elementary particles behave you can deduce how anything in the universe behaves.
You claim that there is no such thing as "emergence" right? So everything is causal?
With complete understanding any and all superpositional phenomena disappear.
Emergent phenomena disappear.

Well, we don't have a computer strong enough to perform calculation for this number of atoms. We also have problem with memory too.
Why do you need a computer and memory if you can just imagine the system and all of its components?

No.
Why not? You said that comprehension/understanding means you can imagine something.
Can you or can you not imagine a system with 10^23 atoms?
If you are comfortable admitting that all of our theories/models are incomplete, then you also need to admit we are working with heuristics.
For complete models lead to perfect deduction.
