The Information Boundary Principle: Thermodynamic and Causal Necessity of a High-Energy Scalar Meta-Field

ABSTRACT Standard cosmological models currently face two critical deficits: the violation of energy conservation at the singularity (the "Free Lunch" problem) and the paradox of retro-causality in delayed-choice quantum experiments. This paper proposes a unified solution: the existence of a high-energy, infinite scalar potential (the "Meta-Field") existing within a 5-dimensional bulk manifold. We propose that the observable universe is a local phase transition within this larger field, governed by an Information Boundary that enforces causal stability. By this paper, we demonstrate that wave function collapse is a mechanical response to a "Minimum Information Threshold" (Delta I_min), mathematically related to the Landauer limit. This model resolves the conflict between General Relativity and Quantum Mechanics by defining spacetime as a non-volatile data structure preserved by the bulk geometry, thereby eliminating the need for many-worlds interpretations or time-travel paradoxes. This paper serves as the direct mechanical extension of the foundational cosmological framework established by the author on November 22, 2025, in the preprint titled The Meta Field Substrate and the Information Boundary Principle: Cosmological Extension of Quantum Information Bounds. Whereas that foundational work delineated the existence of the Meta Field and the Minimum Informational Boundary, the current analysis defines the concrete physical architecture that executes those boundary conditions. Moving beyond the abstraction of pure mathematical operators, this paper introduces the specific structural mechanics of frequency dynamics operating within a fifth spatial dimension. These 5th-dimensional frequency mechanics provide the actual, physical cosmological structure that underpins and drives the previously established boundary parameters, securing the continuum from abstract theory to physical mechanics.
