We often hear about universes splitting, they're being multiple versions of the universe of ourselves. I don't know if that's just sort of, we've got carried away with the science fiction or if there's better language that we should be using to describe what the physics actually says. You know, this debate over language goes back to Everett himself and his thesis advisor, who was John Wheeler,. They butted heads a little bit because Everett introduced the language of the universe splitting. So he really hung on to that language as being metaphorical, but vivid and accurate.
