A Unified‑Medium Theory of Global Dark‑Energy Superfluid: Unifying Four Fundamental Forces, Interpreting the Essence of Spacetime and the Origin of Matter

This paper proposes that the global dark‑energy superfluid is the fundamental medium filling the whole universe, and constructs a new unified‑field theoretical system. It re‑interprets the underlying physical nature of spacetime, realizes the unification of four fundamental interactions, and explains the origin mechanism of matter. Many long‑standing puzzles in modern physics can be explained by the hydrodynamic effects of this superfluid medium.This preprint presents the qualitative theoretical framework, hydrodynamic explanations for fifteen classical physical puzzles, ground‑laboratory verification schemes and astronomical observational predictions. The full set of quantitative equations will be published in subsequent complete papers.This work is for academic exchange and establishing original‑priority timestamp only.
