Dimensional Cascade Cosmology: Toward a Unified Account of the Big Bang, Dark Matter, Dark Energy, Gravity, and Quantum Fields

A conceptual framework proposing that higher spatial dimensions are thermodynamic states requiring exponentially increasing energy to sustain. As entropy increases, each dimension collapses into the one below in a cascade, transferring its energy downward. This single mechanism is proposed to explain the Big Bang, dark matter, dark energy, quantum vacuum fluctuations, primordial and supermassive black holes, the James Webb age anomalies, the geometric origin of gravity, the strong nuclear force, the immense energy stored in atoms, E=mc² as a dimensional conversion equation, the hierarchy problem, and the ongoing nature of the collapse visible in black holes today. The framework is cyclic — when energy fully disperses to its lowest dimensional state, quantum nucleation triggers a new cascade. Fourteen testable predictions are identified distinguishable from standard cosmological models.
