So, stars between 50-130 solar masses don’t directly form black holes because they blow themselves apart at the end of their lives. I got that from the article.

So, stars between 50-130 solar masses don’t directly form black holes because they blow themselves apart at the end of their lives. I got that from the article. Is the idea that a black hole less than 50 solar masses should usually evaporate before it can gain enough mass to fall into that gap? Edit: or is it just that there shouldn’t be enough around for a smaller black hole to “eat” to become that big?

Black Hole evaporation is incredibly slow in the 1+ Solar Mass range (~2.1 * 10^67+ years). http://xaonon.dyndns.org/hawking/ http://xaonon.dyndns.org/hawking/ Also, another astrophysics took the other side of the bet as a 50/50. So, it was not considered all that unlikely. PS: There is normally a limit to how fast black holes can eat, but that’s irrelevant when two black holes collide.
