““uniform space have multiple solutions, then eternal inflation will create infinite regions of space instantiating each of those solutions—this is the Level II multiverse. • Many physical laws and constants that are unchanged across a Level I multiverse may vary across the Level II multiverse, so students in Level I parallel universes learn the same things in physics class but different things in history class, while students in Level II parallel universes could learn different things in physics class as well. • This could explain why many constants in our own Universe are so fine-tuned for life that if they differed by small amounts, life as we know it would be impossible. • This would also give many numbers we’ve measured in physics a new meaning: they’re not telling us something””
