Time, Entropy, Global Time, Local Time,Proper time and Gravitational Time Dilation Mechanisms -The Quantum Thermodynamics Bridging Thermodynamic Time, Relativistic Time and Quantum Field Theory Time Parameters Zou Zhi Kai 邹志凯 zhiyan.zou@foxmail.com ShenZhen, 518000,China https://orcid.org/0009-0000-4279-1064 Abstract:This study presents a novel discrete model that unifies time and entropy through a spacetime mapping framework. The model rigorously satisfies the thermodynamic arrow of time while maintaining consistency with conventional entropy principles. By establishing fundamental connections between global time (cosmic transformations), local time (regional spacetime dynamics), and thermodynamic evolution, it provides a computational foundation for physical simulations, and provides a physical mechanism explaining gravitational time dilation. Key theoretical implications include deriving time's directionality from quantum spacetime network dynamics, explaining light-speed invariance, and proposing dark energy/matter as emergent phenomena of spacetime's ground state. A distinctive falsifiable prediction suggests a measurable difference between positron and electron magnetic moments due to chiral quantum coupling. The model offers three foundational constraints for computational physics: thermodynamic conservation laws, entropy-driven evolution, and least-action path selection. This framework bridges discrete spacetime dynamics with macroscopic phenomena while proposing testable quantum signatures.
