Bonus video - extended clip cut from GR in 7 Levels
Added 2021-02-18 17:43:20 +0000 UTCThis is a clip that didn't fit into the main "General Relativity in 7 Levels" video (https://www.youtube.com/watch?v=eNhJY-R3Gwg), but since I polished it up to release as an "extended" feature on Nebula, I figured I would share it to patrons, too!
No charge for this post, of course.
