This strange “spacetime crystal” can suddenly become a black holehttps://www.sciencedaily.com/releases/2026/08/260829035225.htm
Physicists have mathematically captured a bizarre “spacetime crystal” that can either dissolve or collapse into a microscopic black hole after only a tiny change in energy. Their breakthrough came from an unusual trick involving infinitely many dimensions, potentially giving researchers a new tool for studying primordial and microscopic black holes.
