Episode notes

We assume that the early universe started with very, very low entropy. And then we conditionalize on that when we make predictions about the past. What we actually think happened in the past is utterly different than what you would get just on the basis of predicting from the current macro state. This is so in and in how we think at it is very difficult to break out of just assuming that past hypothesis.

Welcome to the March 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!
