Black holes can split in two — but only if they spin at extreme speeds
AI-summarised brief · reviewed before publication
A new study published in Physical Review D shows that a single black hole could split into two if it spins at near‑maximum speed. The researchers found that the extreme rotation allows a temporary loophole in thermodynamic laws, enabling the event horizon to divide in a “pair‑of‑pants” topology. The resulting pair would separate only if one fragment is significantly smaller than the other. The team estimates that primordial, tiny black holes are most likely to undergo this split, potentially producing detectable gamma‑ray signatures.
