As two core approaches for humankind to explore cosmic laws, modern natural science and traditional Daoist system have fallen into an extreme split in contemporary times. Constant subdivision of modern scientific research has made it lose the unified underlying logic of the universe; meanwhile, researches on traditional Daoism gradually break away from empirical exploration of natural origin and degenerate into empty metaphysics and humanistic preaching. Based on the original cosmic outlook of Tao Te Ching in Chu Bamboo Slips and Silk Manuscript versions and combined with the physical logic of modern spacetime and dark energy, this paper puts forward a unified paradigm for human beings to understand the world in the future. The overall origin framework of Daoism defines the top-level cosmic laws while modern mathematical science realizes quantitative empirical verification, putting an end to the dual opposition between empty metaphysics and rigid formulas and building a brand-new unified research system for future natural science.
