Torsional Dynamics as a Unified Solution for the Cosmological Constant and Dark Matter Problems

This work reports the discovery that both the cosmological constant and dark matter arise as effective manifestations of spacetime torsion. By treating spacetime as an active torsional medium, the model reproduces cosmic acceleration, flat galactic rotation curves, and singularity regularization without invoking Λ or any dark matter component. These results challenge the foundations of the ΛCDM paradigm and identify torsion as a fundamental physical degree of freedom of the vacuum.
