>the behavior of the simulation would be the physical laws of the universe they live in. That's just a tautology. Yes the code of the simulation are the laws of physics for the beings living in the simulation. But the point of a historical simulation is to simulate your own universe. Not a completely different universe. We should expect simulated Earth to be exactly identical to real Earth. Or at least you shouldn't be able to tell the difference. So we should expect the laws of physics to appear the same, but things that require lots of computing power should fail. We shouldn't be able to simulate universes within our own simulation. That would be a pointless waste of computing power.

> We should expect simulated Earth to be exactly identical to real Earth. If a best-effort ancestor simulation is made, we should expect the laws of the simulation to be identical to the laws of the root universe to the limit of the resolution of the simulation. > Or at least you shouldn't be able to tell the difference. So we should expect the laws of physics to appear the same, but things that require lots of computing power should fail. Except, that if we are in the simulation, we have no reference point as to what the actual laws of physics are in the root universe, so we have no way to distinguish between our universe being the root universe operating by the "real" laws of physics and our universe being a simulation which fails in some respect with regard to the root universe. The only way to detect the latter case is to be in the root universe and observing the simulation. Which we could do for a simulation we create, but not for a simulation we are in. (And, the "things requiring lots of computing power should fail" expectation is unwarranted, at least from the perspective of being something that could be observed from inside of the simulation.)
