There's no such thing as physical distance between many worlds. In quanta mechanics and the many worlds interpretation, the thing that matters is the wave function of the universe. For each different world, there's a different copy of space. If you change the physical situation in one of those worldsa, the other world doesn't notice, right? It will never notice. So i'ma hundred % sure that's the best way to think about it but that's how i think abot it right now.
Welcome to the October 2021 Ask Me Anything episode of Mindscape! These monthly excursions are funded by Patreon supporters (who are also the ones asking the questions). I take the large number of questions asked by Patreons, whittle them down to a more manageable size — based primarily on whether I have anything interesting to say about them, not whether the questions themselves are good — and sometimes group them together if they are about a similar topic. Enjoy!
