my understanding is that the theory posits primordial black holes with an event horizon smaller than a hydrogen nucleus,and have masses that are tiny, so interactions are uncommon and week.
- bell-cot 9mo agoThe article talks about masses of 10^17 to 10^23 grams being prime candidates for detection. (And also about 10^14 gram ones - in their final stages of evaporation, and thus a different sort of detection problem.) If I'm not fumbling numbers, a 10^20 gram PBH is good for ~700,000 g's at a distance of 1 meter. And 7^9 g's at 1cm. Close interactions might be uncommon (unless the PBH is "orbiting" within a star or planet), but they would not be weak.
