Peter solfest says that protons in the universe are not perfectly stable. This means they could decay into other particles, such as a black hole. But even then there is something called gravity and it would happen if you waited long enough. Peter: Even lumps of iron will eventually go away - we just don't know how.
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!
