Infinite Fractal Descent: A Unified Theory of Scalable Discrete Iterations, Computational Mass, and the Informational Regime

The reconciliation of General Relativity with Quantum Mechanics remains stalled by the assumption of a continuous spacetime manifold. This paper proposes the Infinite Fractal Descent (IFD) theory, a paradigm shift modeling the universe as a discrete, stepped recursive algorithm. By redefining Mass as iteration density, Radiation as surface-level wave-chains, and Time as the fundamental Universal Tick ($T_u$), IFD establishes a "Recursive Closure" where gravity and geometry emerge from the informational substrate. We derive the Fractal Density Hypothesis ($M \propto n/V$), integrate the 720-degree Orthogonal Lock for 4D stability, and reframe the Big Bang as a "Universal Up-Conversion" or "Big Flash" event.
