In Eliezer’s realist, MWI interpretation, there are definitely “worlds” in which the bomb explodes; they can have small amplitude but what we see in our world is because of events that straightforwardly happen in those other worlds. And of course there aren’t really multiple worlds, there’s one world, only part of which we can see and interact with once we’ve separated through decoherence.
