Re: SWaB: debunking 70 Msun BH find
So black holes of 70 solar masses are common as it turns out, and there was nothing special about the previously theorized limit of 20 on these kind of black holes. Anyway, my takeaway. I also find it interesting that many stars do not form black holes at all, but instead burn up heavier elements up the periodic table.

It depends on the initial mass and composition, rather strongly.helicon wrote: ↑Tue Dec 03, 2019 9:03 pm So black holes of 70 solar masses are common as it turns out, and there was nothing special about the previously theorized limit of 20 on these kind of black holes.
