Universal Hydromechanical Law

This paper presents a cosmological model based on the Law of Universal Hydromechanics, in which the universe is described as a continuous fluid with memory, capable of storing, transmitting, and transforming information through internal gradients. From a fundamental action, the field equations governing the fluid's dynamics are derived, including a master equation that unifies pressure, density, memory, and acceleration. The model reproduces cosmological phenomena without resorting to hypothetical entities such as dark matter, dark energy, gravitons, or unobserved fields. Applications are presented to galactic dynamics, cosmological expansion, photon propagation, the structure of time, and the formation of matter as memory states of the fluid. Observable predictions are derived, and a spherical, pulsating universe with inherited memory between cycles is proposed. The hydromechanical approach offers a unified reinterpretation of fundamental physics, providing a coherent, falsifiable, and mathematically consistent framework for understanding the structure and evolution of the cosmos.
