Episode notes

There is a regime in which the excitations of that field look like particles. In other regimes they don't look very particle-like at all, right? Inside a proton, the gluon fields do not look like individual gluons because they're not small perturbations of the vacuum. And maybe in a black hole, near the singularity, there's really no regime inWhich the gravitational field looks like a collection of gravitons. So gravity has to interact with everything.

Welcome to the August 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. Enjoy!
