For a while, physicists hoped black holes weren’t real. Their event horizons trap even light, creating paradoxes, while the singularities inside suggest impossible infinite density. For centuries, scientists searched for a way out of this cosmic nightmare. One remaining hope is the Planck star: a dense core of frozen Big Bang energy hidden inside a black hole.
