There are two difficult to explain a symmetries in physics that i struggle with understanding. One is the microscopic existence of an arrow of time, when the laws of physics on the micro scale are in variant under time reversal. The other is predominance of matter over anti matter. Gagwen group two questions together, cause they are about the matter anti matera symmetry in the universe. Klyde schechter says there are two. No credible person believes that.
Welcome to the September 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!
