Holographic Discrete Unified Cosmology: An Emergent Spacetime Model Based on Minimal Geometric Units and Thermodynamic Drives

We introduce Holographic Discrete Unified Cosmology (HDUC), a conceptual framework in which spacetime is treated as an emergent approximation to an underlying discrete, dynamical causal network. Within this setting, we outline a “Dual Line” coupling picture in which matter degrees of freedom are represented as topological excitations on a background geometric graph, and we interpret the speed of light c as a geometric conversion factor relating spatial updates to causal (temporal) updates of the network. We further motivate a thermodynamic/information theoretic viewpoint in which inertial effects and gravitational dynamics admit an effective description in terms of update constraints and entropy maximization, consistent with existing entropic gravity and holographic arguments. Finally, we propose a phenomenological program for confronting the framework with cosmological and high energy astrophysical observations, including potential implications for late time acceleration and signatures associated with non-singular high-density states (e.g., “Planck Star”–like scenarios).
