- <p>This work proposes a coherence field framework for galactic dynamics in which the weak gravity regime is governed by a scalar field associated with the structural coherence of spacetime.<br>Within this approach, the empirical Radial Acceleration Relation observed in galaxy rotation curves emerges as a regime dependent modification of the gravitational response. In the quasi static galactic regime the angular structure of the field reduces to an effective radial scalar mode, leading to a modified Poisson equation and an additional gravitational contribution at low accelerations.<br>The resulting dynamics reproduce the characteristic scaling observed in disk galaxies, where the observed gravitational acceleration becomes proportional to the square root of the product between the baryonic acceleration and a characteristic acceleration scale.<br>This characteristic acceleration scale appears to be close to the cosmological acceleration scale associated with the expansion of the universe, suggesting a possible connection between galactic dynamics and large scale properties of spacetime.<br>The framework provides a phenomenological description linking baryonic matter, gravitational potential and a coherence field that modifies the weak gravity regime. The work aims to provide a conceptual and mathematical basis for interpreting galaxy rotation systematics without invoking large quantities of non baryonic dark matter, while remaining compatible with standard gravitational dynamics in the high acceleration regime.</p>
