Modern fundamental physics is plagued by fragmented theories, redundant hypotheses and abstract model constructions. Multiple theoretical systems coexist yet fail to integrate microscopic matter, macroscopic motion and high-energy cosmic phenomena, giving rise to numerous complex, metaphysical conjectures lacking empirical evidence. Based on the core idea of the grand cyclic unification of photon origin, this paper clearly distinguishes pure photon energy state and bound matter state, and achieves the ultimate unification of matter and energy, identifying photons as the sole fundamental cosmic unit. Photons inherently possess two intrinsic properties: constant speed of light and pure energy, with no mass or fixed volume. Discarding tedious microscopic derivations, this paper constructs a complete theoretical system from seven dimensions: macroscopic physical framework, fundamental matter composition, hierarchical evolution of fundamental forces, origin of charge spin, boundaries of civilizational development, cognitive philosophy and closed cosmic cycles. Its core arguments are as follows: high-energy photons converge and get confined via the strong self-locking mechanism, forming three types of fundamental particles—protons, neutrons and electrons, with confined photons remaining the intrinsic substance inside particles; differences in spin directions of confined photons generate positive and negative charges, the prerequisite for the existence of electromagnetic force; the strong force, electromagnetic force and gravitational force function progressively. The strong force acts on all microscopic units with mass, the electromagnetic force constructs atoms, molecules and tangible matter, and macroscopic gravitational effects emerge after massive accumulation of matter. The three fundamental forces collectively constitute the primary driving force of cosmic operation. This theoretical system confirms that the unification of photon origin will eliminate various fictitious physical models and expand pathways for human scientific and technological progress. Nevertheless, the closed cyclic rules of light cannot be broken; all substances ultimately return to pure photon energy. Objective upper limits exist for human technological exploration and cosmic cognition, dispelling various illusory assumptions about eternal existence and transcendence of physical laws.
