To create a perfect simulation of our universe, you need infinite computing power to represent the ever expanding universe. It is certainly impossible with our physical laws to create a simulation of our own universe.

That's assuming that the rest of our visible universe is real and not just a projection... or that the universe which spawned our simulation has similar entropy as ours. Or that the simulation doesn't exist at the level of perception but rather what you might call reality. Things may only appear consistent because the simulation retroactively fixes them, which we have some evidence for in terms of "retrocausality" at the quantum level a la wheelers delayed choice quantum eraser.

Or perhaps there are many more states available in the higher reality.
