In general relativity, if the background. is completely stationary, then energy would be conserved. But that's not true in the expanding universe. The Higgs field has a non-zero value in empty space and therefore breaks symmetry of electroweak theory. This leads to a non-conservation of charge of the electroweak part of the charge. So these are tricky questions, but good ones.
Welcome to the November 2022 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!
