Black holes can evaporate over time.

Black holes, predicted by Einstein's theory of general relativity, are regions in space where gravity is so strong that nothing, not even light, can escape. Stephen Hawking's groundbreaking theory of Hawking radiation suggests that black holes can actually emit particles and energy, gradually losing mass over time. This process, known as black hole evaporation, occurs on an extremely slow timescale for larger black holes, but for smaller ones, it could lead to their eventual disappearance. This concept challenges traditional ideas about the permanence of black holes and raises intriguing questions about the ultimate fate of these enigmatic cosmic entities.
