The arrow of time is all the ways in which the past is different from the future. Entropy was lower in the past will be higher in the future, he says. The reason why there are all these arrows of time is because entropy is creasing a so that is the single thing that enables all these other asymmetries between past and future.
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!
