While black holes are commonly known to merge, researchers investigated whether the reverse process is physically possible under Einstein's theory of general relativity. The study found a narrow opening for extremely fast-spinning black holes where rapid rotation improves the entropy balance. However, no such splitting event has ever been observed in the universe.Why it mattersAstrophysicists normally study
