Episode notes

In general relativity, gravity is the force that pulls objects together rather than pushing them apart. The theory has been used to explain why galaxies and people fall into each other in a gravitational field. But Betan Betan says there are some problems with this explanation of how things move on geodesics. He thinks it's wrong because dark energy does not dilute away as the universe expands.

Welcome to the September 2022 Ask Me Anything episode of Mindscape! These monthly excursions are funded by Patreon supporters (who are also the ones asking the questions). We take questions asked by Patrons, whittle them down to a more manageable number — 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!
