Here is what the page “Black Holes Spinning Near Maximum Rate Could Split in Two, New Calculations Suggest” contains. A new theoretical study published in Physical Review D explores whether a single black hole could split into two smaller ones—a process that would be the reverse of the familiar black hole merger. The research, titled "When Black Holes Admit Pair-of-pants Topologies," uses mathematical topology to investigate conditions under which a black hole could fission. Key to the possibility is spin: black holes rotating near their maximum allowed rate might, under certain circumstances, become unstable and break apart.
This challenges the long-held assumption that black holes only grow by merging and never divide. The study does not claim such events are common, but it provides a theoretical framework for how they could occur. If confirmed, it would have profound implications for our understanding of black hole thermodynamics and the evolution of the universe.
