Episode 27: Where the Sidewalk Bends

We’re starting off the new year right by getting ahead of the curve! In this topsy-turvy episode, we tackle the stretching and curving of non-Euclidean geometry -- where it came from, why it teaches us about black holes and the shape of the universe, and how conformal diagrams help us wrap our minds (and our spacetime) around it all. Alex amazes with ascending audio, Will gives the all-clear to keep eating Pringles and Malena explains how theorists can help save trees.    Astrobites: https://astrobites.org/2020/12/03 https://astrobites.org/2020/11/23   Penrose’s Nobel Prize: https://astrobites.org/2020/10/15 Space sound: https://soundcloud.com/nasa/quake-sol-173
