I always wondered about the "computability of the universe" and its compressibility. If the universe is actually compressible, then object permanence may actually be a trick, like it is in video games. Objects are generated on demand and deleted to save space and processing. If it's not compressible, which is where I lean, then the full universe must be fully computed every time. No savings can be made, and any delay in computing an object might propagate and cause recalculation cascades for other objects. I lean this way because from my layman's understanding, quantum mechanics act similarly to random seeds, which increases entropy by a lot. If it's not compressible, then the smallest computer able to simulated the universe is at least as big as the universe itself.
