A Preliminary Attempt toward a Unified Framework for the Arrow of Time: Chiral, Modular and Topological Considerations

This work presents a preliminary, exploratory framework aimed at unifying the origin of the arrow of time, rooted in left-handed chirality, modular flow, and RP^3 topological structure. We elaborate the physical consistency between cosmic chirality, unidirectional time evolution and entropy increase, and clarify the core logical connection between algebraic topological constraints and the prohibition of right-handed configurations. Notably, this framework remains in an early developmental stage, with no claim of rigorous mathematical self-consistency proof or complete theoretical verification at present. The mathematical rigor and complete formal proof are left for future in-depth research. This paper merely provides a tentative physical perspective and initial theoretical construction for further exploring the fundamental origin of the arrow of time.
