Study suggests tiny primordial black holes may be hidden in asteroids and ancient structures

A new study suggests that tiny primordial black holes, formed shortly after the Big Bang, may be hidden in asteroids or ancient buildings. Researchers propose innovative methods to search for these elusive objects, which could help explain dark matter. These primordial black holes are much smaller than typical black holes, weighing between 1,017 and 1,024 grams. If captured by a planet or asteroid, they could consume the liquid core, leaving behind a hollow structure that might be detectable through its unusual density. The study also indicates that a fast-moving primordial black hole could create a narrow tunnel in solid matter, potentially identifiable with an optical microscope. The findings will be published in the December issue of Physics of the Dark Universe.
