If the solar system is fully simulated but the rest of the universe is only a sketch, then my beliefs about the Sun may be correct, but my beliefs about Alpha Centauri may be wrong. If 2019 is simulated but 1789 was not, then my beliefs about the French Revolution may be false, but my beliefs about the contemporary United States may be correct. Still, we’ll be right about those closer-to-home aspects of the universe that are present in the simulation.
