Unification of the Yijing's 64 Hexagrams with Chen's Superstring Theory (CST): A Fundamental Theory Framework for Everything Based on String State Coding

Abstract Based on the core premise of Chen's Superstring Theory (CST)—"the ultimate unit of the universe is a three-dimensional energy string at the Planck scale"—this paper proposes that the 64 hexagrams of the Yijing are essentially a "quantitative coding system for cosmic energy string states." By defining gravitational strings as yang Yao (A) and repulsive strings as yin Yao (B), a correspondence between 6-line hexagrams and energy string states is established, achieving complete coding of Standard Model particles, dark matter, and dark energy. Research shows that the string state ratios of hexagrams (pure string state, 5:1, 4:2, 3:3) directly correspond to the interaction types and stability of particles, while Yao transformation is equivalent to the dynamic energy transfer mechanism of string state transition. This framework not only reveals the underlying isomorphism between the Yijing's philosophical thought of "yin and yang interdependence and eternal evolution" and modern physics but also constructs a self-consistent unified system of "string state → hexagram → particle → cosmic evolution." It proves that the Yijing is an ultimate physical framework describing cosmic dynamic evolution, and traditional Western physics (quantum mechanics, relativity, etc.) are local special cases under Earth's spacetime conditions.
