University of Southern Denmark researchers study black hole splitting

A new theoretical study published in the journal Physical Review D suggests that black holes may be able to split into two or more smaller black holes under specific circumstances. While black holes are known to collide and merge into larger objects, researchers from the University of Southern Denmark investigated whether the reverse process is physically possible.

The study indicates that while splitting is unlikely under most conditions, extremely rapid rotation might allow a black hole to split apart. Francesco Sannino, a co-author of the study and professor of physics, noted that the research investigated the physical laws that typically prevent such an event and identified the specific conditions that might allow it to occur.
