The original idea came from peche and quin, roberto peche and helen quinn. They were trying to solve a problem in quanofield theory called the strong c p problem. Axions are a hypothetical particle that were invented for a completely different reason. But at least it was not invented to be the dark matter.
Welcome to the May 2022 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!
