Matrix Node Theory: A Deterministic Theory of Everything (TOE) with Validated Tests

Matrix Node Theory (MNT) presents a deterministic, discrete-space framework that seeks to unify quantum mechanics, general relativity, and the Standard Model of particle physics. In this model, all physical phenomena emerge from a fixed lattice of interacting nodes, where resonance thresholds and coupling dynamics govern the behavior of matter, energy, and spacetime. This document introduces a fully self-contained derivation of MNT’s governing principles, including the emergence of $\hbar$, $c$, $G$, and $\Lambda$ from first principles, and shows how particle formation, wavefunction collapse, and black hole information retention arise naturally from the lattice dynamics. It includes over a dozen testable predictions that align with or challenge existing experimental data from CERN (ATLAS/CMS), LIGO/GWOSC, and XENONnT. Also included are precise comparisons with CODATA and PDG values, proposed LHC resonance searches, gravitational-wave ringdown mode analyses, and dark matter detection strategies. Finally, the work contrasts MNT with major contemporary TOE candidates—such as String Theory, Loop Quantum Gravity, and Causal Sets—highlighting its deterministic and testable nature. The accompanying reference manual provides validation tables, simulation frameworks, and detailed experimental procedures, making this submission suitable for theoretical and experimental review.
