In the first moments of the Universe, black holes the size of an atom but with the mass of an asteroid were born. Today, their invisible swarm may hold galaxies together — and explain the mystery of dark matter without new particle physics.
🎯 An asteroid-mass black hole is microscopic: passing through Earth, it would leave only a thin tunnel and cause weak tremors. The chance of such an event is extremely small.
