The center of a black hole might not be a point of infinite crushing density, but a geometric 'throat' that leads to a new kind of space.

The Takeaway
This model suggests that a fundamental 'minimal length' prevents the creation of a singularity—the place where all physics breaks down. Instead of an end-point, black holes may contain a stable geometric structure that avoids the 'infinite' density problem entirely.
From the abstract
We reveal that a fundamental minimal length naturally replaces the Schwarzschild singularity with future infinity, formalizing the ``asymptotic throat'' as a geometric inevitability. This scheme avoids the topology changes, multiple horizons, and universe towers characteristic of existing regular black hole models. We establish a general regularization framework, construct explicit examples with their physical sources, and show that the surface gravity and Hawking temperature remain unaltered. T
