Based on the framework of Momentum Unit Evolution Theory, this paper re-examines the co-evolution mechanism of large-scale galaxies and the problem of dark matter existence. By introducing the principles of "local rigid connection" and "mutual unloading of momentum deviations", a new model is proposed that explains the flatness of galaxy rotation curves without the need for dark matter, and dark matter is inconsistent with extensive statistics. This is a major loophole in traditional theories. Therefore, it can be determined that dark matter definitely does not exist. This model shares the same underlying logic as the formation mechanisms of ordered structures commonly found in nature (synchronized pendulums, crystal growth, geometric patterns, etc.) — each unit in the system mutually unloads excess momentum deviations through interactions, ultimately achieving a co-evolution state with consistent phases. This mechanism requires no dissipation, no information exchange, and only appropriate constraint conditions (such as gravitational potential wells) to be realized. This paper also distinguishes the essential differences between the feedback-based ordered structures of living systems and the momentum deviation unloading mechanism of physical systems, providing a unified perspective for understanding the self-organization phenomena of the universe from the microcosm to the macrocosm.
