Episode notes

Inflationary cosmology was a candidate for generating the tiny density perturbations that would grow into galaxies and structure today. But there was another candidate, cosmic strings which could easily be formed in the early universe. Cosmic string predictions were wildly ruled out when they weren't compatible with what we saw. The basic problem was that the inflationary predictions are all made very early and they sort of evolve in lockstep since then.

Welcome to the May 2023 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 Patreons, 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!
