Briefings

A theoretical study published in Physical Review D explores whether a single black hole could split into two smaller black holes via pair-of-pants topologies. The research suggests this event might occur when a black hole spins near its maximum possible rate, potentially causing it to fragment. The study provides a framework for understanding rare gravitational collapse scenarios but acknowledges significant theoretical gaps regarding the stability of such configurations.

Key points

• A single black hole could theoretically split into two smaller black holes if it spins near its maximum rotational speed.
• The theoretical framework relies on pair-of-pants topologies, a specific geometric arrangement of spacetime that allows for such fragmentation.

Context

This research addresses a fundamental question in general relativity regarding black hole dynamics. Understanding these rare, high-energy events is crucial for modeling the universe's most extreme gravitational phenomena and testing the limits of known physics.

Limitations

The study is theoretical and relies on mathematical models rather than observational data. It does not confirm if such events actually occur in nature. The specific conditions for maximum spin and topological stability remain unverified.
