As always an excellent summary and well-written.

I’m saddened, however, by your evident refusal to mention the Great Star Eater Zog, which is the real explanation of why the 25-solar-mass star winked out of existence: Zog was hungry. Einstein himself was aware of this important phenomenon, hence his famous equation that relates Zog to meals multiplied by the square of consumption: Z = mc2

(Yes, I’ve read one too many ludicrous comments on sensible articles such as yours, and so it’s time for a little heavy-handed parody. In Russian we might also make reference to the дурак equation…)

Anyone who enjoys my articles here on Medium may be interested in my books Why Democracy Failed and The Praying Ape, both available from Amazon.
