Dark Energy as Thermodynamic Internal Energy: A Wormhole-Driven Entropy Model

This paper presents a speculative thermodynamic framework proposing that dark energy is nota cosmological constant or an external field, but rather the internal energy of the universe as athermodynamic system. We suggest that transient quantum wormholes may enable nonlocal energytunneling into our universe, resulting in increased entropy and consequent expansion. This modeloffers a reinterpretation of virtual particles as observable effects of these energy fluctuations, drawinganalogies to classical systems like expanding gases. While direct detection remains beyond currenttechnology, we outline possible indirect observational signatures such as vacuum fluctuation anoma-lies and cosmological entropy shifts. The proposed theory remains consistent with local conservationlaws and the CDM model, while offering a novel physical origin for dark energy grounded in quantumgeometry and thermodynamics.
