That seems rather extreme, because the probablity that we are in a "regular" "magical" universe is already vanishingly small and we would truly be safe in ignoring it. Even the probability of observing a single large scale violation of the laws of probability is vanishingly small. ("Magical" universes suffer from repeated large-scale violations.) Going beyond that and asking for consistency between the physics of the large and the small is really gilding the lily. I don't see what would motivate you to draw the line there. Hal Finney
