Life of Cosmos: The Feldt–Higgs Universal Bridge (F-HUB) Theory, Part Two: Measurement Density as the Informational Driver of Cosmic Expansion

Life of Cosmos presents Part Two of the Feldt–Higgs Universal Bridge (F-HUB) framework, advancing a novel informational cosmology in which cosmic expansion arises from measurement density rather than dark energy. Building on Birth of Spacetime, which reformulated mass, gravity, and entropy as emergent properties of structured quantum information, this work formalises the role of observation as an active driver of spacetime stability and expansion. At the core of the paper is the F-HUB Life Equation, which links Reality Persistence to three quantities: cumulative observation, entropy accumulation, and observational density. Each irreversible measurement event collapses quantum states and embeds information into spacetime, generating a thermodynamic requirement for expansion. Regions with high measurement density are predicted to exhibit enhanced classical stability, while sparsely observed regions retain prolonged quantum coherence. The framework is tested using a comprehensive simulation suite and compared directly against observational Hubble parameter data. The optimised Life Equation achieves a reduced chi-squared value of 0.62, outperforming ΛCDM (1.03) without invoking a cosmological constant or exotic energy components. The model reproduces observed expansion trends across redshift while offering testable predictions, including spatial variation in spacetime stability, redshift anomalies correlated with low-observation regions, and measurable decoherence gradients between terrestrial and deep-space environments. Beyond empirical performance, Life of Cosmos reframes cosmic expansion as an emergent thermodynamic response to informational growth driven by observation. If validated, the work positions consciousness and measurement not as passive by-products of physical law, but as fundamental contributors to the evolution and persistence of classical reality.
