Episode notes

There's no such thing as an inside out black hole. The universe is described by cosmological metric to very, very good am precision. Until you get to that level of detail, which the standard model explains very, very well, it's not really worth taking alternative theories very seriously.

Welcome to the June 2022 Ask Me Anything episode of Mindscape! We are inaugurating a slightly different publication schedule, in which these monthly AMA will take the place of one of the regular Monday episodes, rather than being in addition to all of them. A slight tweak that will hopefully make my obligations a little more manageable.

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!
