This paper proposes the Center of Field method to determine the bending of the photon’s path in a gravitational field. The numerical model developed, shows that this bending is independent of the energy of the photon and therefore, it probability. This informs of possible particle structure. Further, as the authors’ research is primarily focused on developing interstellar propulsion physics and technologies, these finding would suggest that navigation systems for interstellar propulsion would necessarily need to account for gravitational fields. Finally, this paper reviews a key Schrödinger axiom.
