Got it. The reference is great, the only final addendum I wanted to mention was whether a neutron stars densities would stop a black hole in its tracks since the paper only talks about the black hole already having been there. (At least to remove the amateur recollection of mine from the reference link, the mention of this possibility happens in the video at 6:18 https://youtu.be/qy8MdewY_TY ) and here’s them talking about a BH punching through earth which seems roughly in line with what you say as well! https://youtu.be/AK44wAvv2E4
