They're suggesting that extremely tiny, lightweight versions of these exotic objects could be forming right over our heads when ultra-high-energy particles, called cosmic rays, from space strike atoms or molecules in the atmosphere. Those newly created black holes would then quickly decay, harmlessly raining subatomic particles down onto our planet and ourselves.
