These tiny black holes, packing the mass of a sizable asteroid into the space of a single atom, could be blasting through our solar system at least once every decade.
If we see it, that would count as a real reason to keep pursuing this delightful idea that all of dark matter consists of black holes spawned an instant after the Big Bang.
Thanks to their immense density, these tiny black holes could exert enough gravitational forces on celestial bodies to account for dark matter's effects on the motion of stars.
Researchers suggest looking for tiny wobbles in Mars' orbit as a way to detect these primordial black holes and explore their connection to dark matter.
