You Surprise Me , Ethan

Regarding your claim that primordial black holes are a “loser” in light of the LIGO results, I have to ask you a question.

Are you completely unaware of this: “Seven Hints For Primordial Black Hole Dark Matter” by S. Clesse and J. Garcia-Bellido, available at https://arxiv.org/abs/1711.10458 ?

You are right that CDM (in the form of WIMPs, axions, sterile neutrinos, or any other member of the ad hoc particle dark matter zoo) is a total loser, but PBHs are a winner — just hitting full stride.
