Geometry: The Interface of Consciousness and Reality in the Quantum-Conscious Nexus

The Quantum-Conscious Nexus (QCN) framework posits a primordial, pre-geometric topological substrate—the Nexus—from which spacetime and physical law emerge via Free Energy Principle (FEP)-driven mechanics involving predictive conscious systems. This paper explores the hypothesis that specific classes of combinatorial and differential geometry form a dynamically emergent interface through which consciousness and the Nexus co-create structured reality. This geometry arises as a lower-dimensional projection of the Nexus, selected and stabilized by FEP. We examine this thesis through two domains: (1) recent breakthroughs in theoretical physics, notably the Amplituhedron, which show that fundamental particle scattering amplitudes can be derived from timeless, pre-spacetime geometric principles, with locality and unitarity emerging as derivative properties; and (2) rare but striking instances of atypical cognitive structuring, seen in the synesthetic and savant abilities of individuals like Daniel Tammet and Jason Padgett, whose minds may access Nexus structure via distinct "quantum filter functions" (F_Q). We further explore a conceptual bridge to the conscious agent formalism of Hoffman et al. (2023), whose agent-based dynamics offer a compelling candidate for the microphysical substrate of Nexus topology. An appendix outlines early mathematical formalisms linking QCN, conscious agent dynamics, and the geometries underlying both physical interaction and structured experience.
