To provide a framework that resolves the Cosmological Constant Problem and Hubble Tension, we propose Symbiotic Infodynamic Equilibrium (SIE) Unified Field Theory. Building upon Mass-Energy-Information Equivalence and Entropic Gravity, we recalibrate Information as the primary physical substrate. Through a discrete Unified Lagrangian, fundamental forces emerge as strict thermodynamic imperatives: Mass is continuous Landauer power, Gravity is entropic surface minimization, and Dark Energy is osmotic pressure. By replacing the spacetime continuum with a finite Planck-scale lattice governed by a Universal Gauge Constraint, we mathematically derive Standard Model parameters (alpha, mass ratios, MOND) from first principles. This inherently provides the rigorous mechanism to bound ultraviolet divergences and bypass mathematical singularities, uniting quantum mechanics and macroscopic gravity by defining physical laws—and their falsifiable empirical signatures—as the strict thermodynamic equilibrium of an information-based universe.
