Why don't heavy stars fuse iron even at the net energy loss? Why heavy stars don't overshoot the iron peak? Iron cores have enough gravitational energy to spend on iron fusion but they don't.
I don’t know who these are intended for, but the fast pace and thorough explanation made it so interesting, I’ll definitely binge watch the rest this weekend! Thank you for this densely informative content
Thanks! They’re aimed at the high school students I teach in IB Physics. I usually ask my students to watch/take notes from these for homework, and then in class we apply the ideas to problems. I’m glad to hear you enjoy them!
