Zero-Energy Fluctuation Dark Matter Model (ZEFD Model)

This paper proposes the Zero-Energy Fluctuation Dark Matter (ZEFD) model. Based on primordial quantum fluctuations and cosmic expansion dynamics, we construct a unified framework for dark matter without introducing new particles or dark energy. The universe satisfies a strict global zero-energy balance: positive matter energy and negative gravitational energy cancel exactly. High-amplitude primordial fluctuations collapse into ordinary matter via expansion freezing, while the remaining non-collapsed fluctuations form dark matter as a spacetime background field. Ordinary matter and dark matter share a common origin and maintain natural spatial correlation. The model establishes a causal relation between cosmic expansion and black hole evaporation: cosmic expansion modifies vacuum boundary conditions near the event horizon and induces Hawking radiation. Hawking radiation is shown to be a local dynamical mapping of cosmic expansion. The ZEFD model unifies ordinary matter, dark matter, cosmic acceleration, and black hole evaporation within one self-consistent framework. It is fully consistent with general relativity, quantum mechanics, and current cosmological observations.
