Episode notes

When you measure a particle in an entangled superposition, the thickness of the world goes down. The amplitude of the branch you're on now is thinner than what it used to be. Locality says that the direct interactions between one cubic centimeter and all of the other cubic centimeters in the universe are only between nearest neighbors. When I poke the quantum fields at a certain location, it directly affects the very closest other fields but does not directly affect anything going on very, very far away.

Welcome to the July 2023 Ask Me Anything episode of Mindscape! These monthly excursions are funded by Patreon supporters (who are also the ones asking the questions). We take questions asked by Patreons, whittle them down to a more manageable number -- 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.

We're experimenting with a new benefit for Patreon supporters: short video (or audio-only) reflections by me on the podcast that just happened. If you've been wondering whether to join up, this could be the time.
