A theoretical study published in Physical Review D examines the possibility of black holes undergoing a pair-of-pants topology. This process describes how a singular black hole horizon might divide into two separate legs.
Why it matters
While ordinary non-rotating black holes remain stable, this research suggests that rapid rotation or extra dimensions could provide a mechanism for splitting. These findings offer potential new avenues for identifying black hole signals.
The study models a black hole horizon forming a trouser-like shape that splits into two legs. Researchers utilized theoretical frameworks involving extra dimensions to determine that mass inequality influences the thermodynamic favorability of the event.
The players
Francesco Sannino
He is a researcher based in Naples, Italy, who co-authored the study regarding black hole topologies.
Physical Review D
This is a peer-reviewed scientific journal that focuses on particles, fields, gravitation, and cosmology.
Quantum Field Theory Center
This research institution is located in Odense, Denmark, and supports work in theoretical physics.
The details
The process requires the resulting black holes to move apart quickly to prevent immediate recombination. Researchers believe smaller primordial black holes are theoretically more susceptible to this fragmentation than larger astrophysical ones.
Timeline
The theoretical study was published in Physical Review D on October 23, 2026.
The Big Picture
This research challenges the long-standing understanding of black hole stability under the standard model of thermodynamics for non-rotating black holes. By identifying a potential loophole for fragmentation, the study pushes the boundaries of current gravitational theory.
This theoretical breakthrough suggests that gamma-ray telescopes may eventually detect unique signals from fragmented black holes. These findings could refine our understanding of primordial black hole behavior in the early universe.
The takeaway
This study highlights the importance of rotation and extra dimensions in testing the limits of general relativity. Researchers hope these theoretical models will guide future astronomical observations of high-energy cosmic events.
