Tiny black holes can form from crystalline spacetime

While massive black holes form from the violent death of stars, researchers have mathematically described a much more delicate birth for their microscopic cousins. These primordial black holes, which can be as small as a medium sized asteroid, may emerge from an unstable state where the fabric of space and time organizes itself into a regular, crystal like arrangement. This state acts as a cosmic tipping point between empty space and a concentrated gravitational sink.
