The Raumvektortheorie (RVT): A Geometrical Solution for Dark Matter and Dark Energy via Dynamic Projection

The Raumvektortheorie (RVT) challenges the fundamental assumption of cosmology -- the Location-Invariance of Gravitation -- by exposing the shortcomings of the 180-Degree Symmetry in ART and SRT. The established Standard Model requires the unproven hypotheses of Dark Matter (DM) and Dark Energy (DE) only because it ignores the diverse projection vectors of space. The RVT breaks this symmetry by introducing 90-Degree and 270-Degree Space Vector Projections and defines the 0-Degree Plane as a Dynamic, Relative Lorentzian Aether (A_Lor). DM is the direct consequence of Projection Divergence (D), which arises when observers at different Space Vectors (R_B) measure the same object. Gravitational effect is location-dependent on perspective. The RVT Gravitational Equation supplements the ART effect (G_ART) with a location-dependent correction term D. The Galaxy Rotation Curves can be corrected without DM. The seemingly accelerated expansion (Dark Energy) is the Projection Drift (dA_Lor/dt) of the relative Lorentzian Aether and does not represent a cosmic energy density. The RVT integrates ART and SRT as special cases of a general, geometric theory that dispenses with the ad-hoc vectors DM and DE and provides a more coherent explanation of cosmic dynamics.
