Emergent Spacetime and Interactions from Quantum Field Angular Momentum Coupling

This paper proposes a unified conceptual framework in which the coupling of angular momentum among quantum fields serves as the sole dynamical postulate. Starting from this single premise, we show that spacetime geometry, causal structure, the arrow of time and entropy increase, and the fundamental interactions can all emerge as collective phenomena rather than independent laws introduced by hand. The framework offers a novel perspective on the deep connections between quantum field theory, general relativity, and thermodynamics, suggesting that the apparent complexity of physical law may arise from a single, simple rotational coupling principle at the quantum field level.
