Physicists talk about a vast landscape of physical realizations, where myriad valleys are related to different universes, each with its own set of natural laws. Which begs the question: If laws vary across the multiverse, how can we understand our own?
Is our universe typical or atypical?
Could physics be moving from a quest for the laws of nature to a quest to explain the origin of the laws of nature? Can we even make quantitative sense of this question? In an infinite multiverse, how can we come up with a probability measure to explain the likelihood that we exist?

for some reason, i find it a hilarious idea: that our universe lies in a set of measure zero, with respect to some measure of "reality."
it's not that i disbelieve it;
i just find the terminology amusing.
imagine it: we're part of some exceptional set that defies Lιttlewood's three principles ..! (-:
