On the Nature of Gravitation and Geometric Drift of Spacetime

In this study, it is shown that inserting geometric drift vectors within definition on tetrads have direct effects on torsion tensor. This contribution reveals an original point of view on gravitation while still being compatible with standard approaches and recent cosmological observations. Theoretical calculations of galactic velocities and critical radii can be made without need of dark matter. The difference between geometric drift vector coefficients are strong candidates to explain dark energy.
