It's pretty cool being on Hacker News and seeing some new science in a field I briefly worked in. The principle scientist on Punch is Craig DeForest who I met a few times at various geo and heliophysics conferences. It's awesome to see he and his team are still out there doing new science.
According to the article, a rock has a 0.000001% chance of having been hit by a PBH in the last billion years. It's entirely possible that not a single human being has been hit by a PBH in the last million years. "Bombarded" doesn't do justice to the low concentration of these projectiles.
