Özet
Black hole singularities still remain a central challenge in gravitational physics. In this work, we present a geometric interpretation of nonsingular black hole cores within teleparallel gravity based on geometric drift vectors. Gravitational effects are encoded in a comoving tetrad framework through a dynamical drift field whose gradients generate torsion rather than spacetime curvature. While the teleparallel equivalent of general relativity reproduces the Schwarzschild behavior in the weak-field regime, nonlinear invariant contributions dominate in the strong-field region, replacing the central singular behavior with a smooth de Sitter-like core. Event horizons emerge as drift horizons associated with the limiting behavior of the geometric flow, and null and time-like trajectories admit analytic extensions across the horizon and central region.
