This model proposes a regular black hole interior structure in spherically symmetric spacetime, suggesting new interpretations of black hole interiors.
Key Points
To develop a model for a regular black hole interior using a radial causal deformation of the Schwarzschild metric.
Introduced a dimensionless radial deformation factor β(r).
Modified the light-cone structure while preserving the Schwarzschild exterior.
Ensured continuity at the event horizon and regularity at r → 0.
Eliminated the central singularity, replacing it with a finite, regular core.
Maintained static and spherically symmetric spacetime.
Achieved finite curvature invariants and smooth interior geometry.
