Physical Review D Paper Shows Extreme Spin May Open Narrow Thermodynamic Window for Black Hole Splitting
Theoretical calculations show black hole splitting remains forbidden except possibly for near-extremal Kerr cases or in extra dimensions. The study supplies precise thermodynamic and dynamical limits rather than claiming observed events. Evidence rests entirely on analytic and numerical modeling without empirical data.
Future high-spin measurements from LIGO-Virgo-KAGRA and next-generation X-ray timing could test the boundary conditions assumed here. Absence of splitting events in the coming decade of data would tighten the allowed spin window and further constrain extra-dimension models.
Sannino: No confirmed splitting signature appears in LIGO O5 catalog above 10 solar-mass systems with spin parameter a>0.98 within 36 months of data release.
