I can’t speak to the scientific value of the paper–actual quote:
We focus on a more exciting possibility: if the OGLE events are due to a population of PBHs then it is possible that the orbital anomalies of TNOs are also due to one of these PBHs that was captured by the Solar System.
But the writers of “What if Planet 9 is a Primordial Black Hole?” get an A for showmanship. Page 5 includes an “exact scale image” of the black hole discussed:
Science papers are always full of figures, but very rarely are they to scale, but in this astrophysics paper, which I’ve never heard of an astrophysics paper having a figure to scale, the authors included a 1:1 scale of a 5 Earth-mass back hole. Sick as hell. pic.twitter.com/HYhv005gTW
