PickVidsBest Cosmology & astrophysics Videos
The 108 Cosmology & astrophysics videos here were recommended by different people across different months. Choose by who it is for: 10 introductory, 8 intermediate, 88 for a general viewer, and 2 for someone who wants the harder derivation. Most of them are an explainer. What they share is that one picture or analogy is used to supply a missing concept. Channels you will keep seeing include PBS Space Time, Kurzgesagt – In a Nutshell, Isaac Arthur.
