Geometric Dynamics Unified Theory (GDUT)

This paper proposes the Geometric Dynamics Unifed Theory (GDUT), a monistic on-tological physical framework based on two axioms. Axiom I: Physical space is a three-dimensional continuous Riemannian manifold. Axiom II: The evolution of space is governed by the pressure fow equation. In this framework, space is the only physical entity, matter is a low-pressure vacuum bubble in space, gravity is the spatial fow driven by pressure gra-dients, and the arrow of time is defned by the monotonic decrease of the pressure-squared integral. This paper does not address the internal structure of any specifc particle. It only estab-lishes the theoretical framework: what space is, how space evolves, how matter emerges from space, and how gravity arises from spatial fow. The structure, motion, and interactions of specifc particles will be developed in subsequent papers.
