The framework developed herein-referred to as Flat Spacetime Gravity (FSG)-constructs gravitation as a relativistic interaction mediated by antisymmetric tensor fields and velocity-dependent couplings, fully consistent with Lorentz covariance and classical field theory.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e Beginning with the kinematical structure of four-velocity fields and rotational bivectors, the theory introduces a natural decomposition into orbital and Fermi components, allowing a transparent separation of spatial dynamics from mixed space-time coupling effects. A Maxwell-type gravitational field formulation emerges, based on scalar and vector gravitational potentials generating sourceful and rotational field components.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eThe work develops: \u003c\/p\u003e\u003cul\u003e\u003cli\u003e\u003cul\u003e\n\u003cli\u003eA complete Lagrangian and Hamiltonian formulation of gravitational dynamics in flat spacetime.\u003c\/li\u003e\n\u003cli\u003eCanonical equations of motion and conserved quantities.\u003c\/li\u003e\n\u003cli\u003eSemiclassical WKB analysis leading to a de Broglie-type wave description for matter interacting with the gravitational field.\u003c\/li\u003e\n\u003cli\u003eModified orbital dynamics accounting for relativistic corrections to planetary motion.\u003c\/li\u003e\n\u003cli\u003eA purely orbital explanation of light deflection without the use of spacetime curvature.\u003c\/li\u003e\n\u003cli\u003eA consistent flat-spacetime treatment of gravitational redshift and time delay effects.\u003c\/li\u003e\n\u003cli\u003eA dynamical cosmological sector in which large-scale expansion, effective Hubble flow, and redshift emerge from the evolution of the gravitational time-rate factor .\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e Throughout the text, all derivations are presented explicitly within a unified mathematical structure grounded in classical relativistic field theory.
