1 The simulation is an enviroment, defined and potentially fully controlled by some external entity.
2 The realm is the pool of functions the simulation draws from. For example, Steam's physics engine (simulation) would be subject to the realm of Physics. This would divorce the simulation theory from Plato's idealism because Plato describes ideas, the simulation is about primitives.
3 There are no computational bounds (ie. I assume there is a computer powerful enough to simulate the entire Universe, assuming the Universe is finite).
4 The Metaverse is the realm the controlling entity resides in, as seen from the simulation.
To blatantly abuse the Entscheidungsproblem, I intuitively suspect we cannot. Is there some argument against that statement?
For example the Sims may be aware of other sims and of themselves, to the extent permitted by their programming, but they are always bound to their programming and so they cannot be aware of the computer or the player.
My argument is the following:
In order to construct a simulation, a conscious entity must have some understanding of the realm it resides in and model the functions of the realm onto the simulation.
For the entity residing in the simulation, the simulation is the realm.
The simulation (by assumption #3) can be a one-to-one mapping of the realm (ie an exact copy of it, probably with some modified constants or extra constructs)
There is an infinite number of simulations
At some point a simulation may be non-complex enough that cannot produce a 1:1 simulation of it. (We probably are such realm). Similarly, a simulation may be simple enough that cannot produce a simulation of its own (the Sims).
My question is this: Assuming a simulation is a subset of the realm, can the simulation ever be fully aware of a function that exists on its metaverse? According to my assumptions above it cannot but there
may be probably is a flaw in my reasoning.
I am aware of the recent efforts to detect a metaverse but as a layman with no understanding of physics, the abstract seemed impenetrable. I would also ask, if it is appropriate to ask such a thing here, a simple explanation of the experiment if anyone can provide one.
