The discussion here seems to make the assumption that all the simulations are running with the same laws of physics. There's no reason why a simulation would need to use the same cosmological constants that ours does. Who knows what the lower level simulation actually looks like.<br><br>Our reality could be working slower than the next level, we wouldn't know it, therefore resources could be much less constrained than we think.,(reply>), It's covered by the first condition of Boströms Trilemma,(reply>), I doubt "slower" can possibly have any meaningful definition in this case. Slower compared to what? Design an observable race.,(reply>), How does this affect the probability that we're living in a simulation? I can't think of any arguments that were made which your comment is relevant to
