It's not so impossible to conceive of a perfectly accurate atomic-scale simluation, capable of mirroring significant parts of our own reality. The problem arises only when you attempt to run the model in real-time. Only at that point do the physical limits of the parent reality come into play. It's possible to short-circuit this fact by pre-computing certain results in advance. But, then what you'd be doing is presenting the simulation with assumptions. Since physical constraints prevent us from operating in real time, and force us to inject pre-fabricated assumptions, this would mean we can't make perfectly accruate predictions, or perhaps start a simulated universe with a "big bang" event, and then fast forward to observe the exact future, or operate with the same concept in reverse and witness mysteries of the past, simply because it doesn't seem possible to force a simulation to accurately operate at speeds faster than the parent universe. At least not without distortions, substitutions and abstractions. Nor does it seem possible to simulate an accurate universe that isn't smaller than the container universe. The simulation must occupy an amount of space within the parent universe, somehow, and yet still leave at least some space for the simulation's operable framework and infrastructure. Thus, the simulation must be arbitrarily smaller than it's outer reality. Since we are hypothesizing, it's not necessary to specify how much smaller, so long as we acknowlege that obvious truth. But could we simulate a small part of the parent universe with perfect accuracy, inside itself? Yes, I think so. Although assumptions would have to be pre-defined for inputs to bootstrap the simulation. Could we simulate one living sentient entity, trapped in a tightly-bound, controlled, claustrophobic prison, an environment devoid of the richness of a raw, unpredictable natural environment? Sure, why not?
