Description
Black hole singularities continue to pose a major topic in almost all gravitational theories. Here we propose a geometric picture for regular (non-singular) black hole interiors in teleparallel gravity, formulated in terms of geometric drift vectors. In a comoving tetrad setup, gravity is described by an evolving drift field whose spatial variations give rise to torsion instead of curvature. In the weak field limit, the teleparallel equivalent of general relativity recovers the standard Schwarzschild solution, whereas in the strong field domain nonlinear terms become dominant and smooth out the central singularity into a de Sitter type core without a need of ad-hoc metric tensor components. Within this framework, horizons arise as “drift horizons,” determined by the asymptotic behavior of the underlying geometry. We give the algebraical relation between main / principal invariants and reformulation of the Lagrangian. Physical meaning of field equations and corresponding solutions are explained. Moreover, it is shown that both null and timelike geodesics can be continued analytically through the horizon and across the central region. Finally, related sub-topics like Cauchy horizons and information loss paradox are discussed.
