Energetic Space Theory (EST) A Scalar Field Framework for Gravitational Interaction, Relativistic Phenomena, and Galaxy Dynamics Without Dark Matter

We present the Energetic Space Theory (est), a scalar field framework in which space is a physical energetic medium described by a single bounded dimensionless scalar field S(r, t) ∈[0, 1]. Every material body generates this spatial energy field; gravitational interaction arises from the gradient of S and from gravitational waves generated at the contact surface where two fields intersect. The theory reproduces Newtonian gravity in the weak-field limit, predicts the correct relativistic precession of Mercury’s perihelion, the observed light deflection of 1.75′′near the Sun, gravitational redshift, and flat galactic rotation curves without dark matter through a boundary-reflection mechanism. The Tully–Fisher relation v4 flat ∝Mgal is derived from first principles. Several unique predictions are identified, includingaforce-enhancement factor(1−S)−1 in strong fields, a universal maximum field strength at S = 1, a sharp physical galaxy boundary at S = 0, and a dissolution timescale for isolated bodies in the intergalactic void.
