The theoretical research focuses on the particle-cause proposition on the wave duality of light in propagation. It specifically examines the graviton’s possibilities in the influence of the light speed, with examples of the Cherenkov radiation and the potential dark-matter prevalence in the ”vacuum” medium. The initial momentum for the Big Bang theory is hypothesized, and the pure mathematical research have been applied in the theoretical analyses for conceptual framework building, with relation to the Dirac notation. The seismic sonic analogy is implied in the conceptual framework in the nonperturbative basis for perturbation, and can be explainable to the phenomena of light speed variations. The bra part of the graviton is formalized, and two possible scenarios predicted with the mathematical assertions.
