Physicists Test Whether Black Holes Could Split

Name: __________________________ Date: __________________

Read the story

A new theoretical study examines conditions under which a black hole might divide. Physical Review D published the paper on October 22; the University of Southern Denmark explained it the following day.

Ordinary non-spinning black holes face a thermodynamic barrier. Rapid rotation may leave a narrow opening, but the resulting objects must also separate. The calculations do not demonstrate an observed split.
