This is specifically a thread for those who are interested in consciousness and physics and mostly for those who believe that reality would collapse without the mind or observer. In a very small proof/arguement, I will show that the order created using set-theory can prove that reality is not observer-dependent.
From now on, I will for this take assume that a subset is a subdimension. There is a specific condition which we must keep in mind when being a subdimension of a larger system[*].
Let us denote consciousness (and everything related to) as a set . Let the universe then be the set . Thus if is a subset of then I can write
It is taken for fact that exists as a subset of that it cannot be an exact copy[*]. No subsystem can model precisely the larger system it is made of. This is conjectured because I believe that can never contain all the information contained in . This conjecture would make sense for consciousness, because whilst our brain takes in two-dimensional images from the outside world, it never models the outside with exact precision.
A final conjecture would be, that the mind exists but the universe doesn't depend on the mind whilst the mind does depend on the universe. This should clear up, once and for all the dichotomy of whether the universe is mind-dependant or not. Taking into consideration that the mind seems to be a late low-energy phenom as well, the mind emerges from the universe not the other way around.
So in short, the universe is not observer-dependent, but the mind is universe-dependent. This means that quantum mechanics may still have a role in developing consciousness because we are ''not outside'' of spacetime.
