FY-Theory The FY Theory of Gravitational Light-Coupling

AbstractThis paper introduces the FY-Theory, a novel physical framework postulating that the speed of light c is not a fundamental constant but a resultant velocity derived from a primordial velocity, FY. The author proposes that FY represents the true universal limit, which is reduced to the observable value of c through a process of gravitational coupling and cosmic friction. By defining the gravitational resistance factor \(Omega ), the FY-Theory demonstrates how light emerges as a product of energy transformation when the FY field interacts with mass densities. The work provides alternative mechanistic explanations for: The nature of Black Holes and the Event Horizon as a physical "braking zone". The Hubble Tension and the accelerated expansion of the universe. The empirical discrepancy between light travel time and comoving distance (e.g., in the galaxy JADES-GS-z14-0). This theory challenges the current paradigm of the absolute constancy of light and suggests that the speed of light is a historically decreasing quantity reflecting the growing gravitational complexity of the universe.
