Unified Mass–Energy Dissolution Cosmology (UMEDC)

The Unified Mass–Energy Dissolution Cosmology (UMEDC) introduces a new paradigm in cosmology, proposing that ordinary matter, dark matter, and dark energy are not independent constituents, but sequential phases of a continuous cosmic transformation. In contrast to the ΛCDM model—which inserts these components as disconnected parameters—UMEDC is built on a physical process of staged mass dissolution: M ⟶ DM ⟶ DE This work presents the first complete formulation of UMEDC, including conceptual motivation, mathematical structure, modified Friedmann dynamics, growth of structure, and alignment with key cosmological observations such as the Hubble tension, early-galaxy anomalies from JWST, and growth-factor deviations. Rather than invoking a static cosmological constant, UMEDC explains late-time acceleration as the thermodynamic consequence of mass transitioning into vacuum-like energy. The full article (50–70 pages) provides detailed derivations, predictive diagnostics, and observational forecasts, inviting the scientific community to test UMEDC against upcoming surveys (Euclid, LSST, CMB-S4). By unifying cosmic components through a single dynamical principle, UMEDC offers not only an alternative to ΛCDM, but a deeper narrative of the universe as a process of continuous transformation.
