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

 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, 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, and the geometric origin of gravity as dimensional incompatibility rather than a fundamental force. The framework is cyclic — when energy fully disperses to its lowest dimensional state, quantum nucleation triggers a new cascade, making the Big Bang a recurring event rather than a unique origin. Ten testable predictions are identified distinguishable from standard cosmological models.
