Small primordial black holes (PBHs) present fascinating theoretical scenarios, such as their interaction with humans without causing immediate harm despite their considerable mass. For instance, a PBH with a mass of about 10^17g is extraordinarily dense yet theorized to pass through a human body without significant injury, which opens discussions about their gravitational effects and their potential role in dark matter chemistry. The conversation also relates to science fiction, with references to Asimov's 'The Hole Man.' Comments suggest a curiosity about stability, growth of such black holes, and Hawking radiation, as well as anecdotal experiences of sharp pains possibly linked to such phenomena. The notion of PMBs passing through us like neutrinos adds another layer of intrigue. While empirical observations are lacking, the implications for both theoretical physics and science fiction are compelling.
