qHIGT: Dimensional Projections and Ontological Foundations for Holographic Information Gravitation Theory

We present the Quantum Holographic Information Gravitation Theory (qHIGT), an ontological extension to HIGT, addressing the fundamental question: "Why is there something rather than nothing?" By formalizing the Buddhist concept of Dharmadhātu as infinite-dimensional Hilbert space and recognizing complex numbers as the mathematical gateway to potentiality, we demonstrate that the apparent "nothingness" (0) and infinity (∞) are mathematically identical. This onto-theory resolves the substrate paradox through dual-aspect monism, wherein organization and geometry constitute inseparable perspectives on fundamental reality. We establish photons as manifestations of pure information, demonstrate mass emergence from organizational density Φ via m = κΦ (yielding E = mc²), and generate testable predictions including correlations between galactic morphological complexity and dark matter distribution (validated: r = +0.42, p < 10⁻³⁰⁰, N = 261,387 galaxies). The framework unifies mathematical rigor (Hilbert space theory), physical mechanisms (geometric derivations), consciousness science (Extended IIT), and phenomenological insights across cultures, providing the first rigorous onto-theory: an explanation not merely of how the universe functions, but why existence occurs rather than non-existence—grounded in derivable constants that emerge naturally from the geometry of reality itself.
