Diffusion of Information Hypothesis XIIIa — The Hunt–Lyra Informational Atlas (World's First Measurement of Informational Luminosity Across 100 Cosmic Systems).

Version 13a marks a defining moment in the development of Informational Cosmology. Building on the Informational Luminosity Law (ILL) and the Hunt–Lyra Parameter (ΩHL), this Atlas presents the first large-scale empirical measurements of informational luminosity across the universe. Using verified luminosity and temperature data from one hundred stellar and galactic objects — from ordinary stars to pulsars, white dwarfs, quasars, and active galactic nuclei — the study quantifies the informational output of radiative systems for the first time in history.   Results show a consistent linear relationship between information emission, energy output, and temperature, confirming the predictive strength of the ILL across over fifty orders of magnitude. Compact and extreme objects demonstrate strong agreement with the Hunt–Lyra Parameter, reinforcing its interpretation as a universal scaling constant linking information, energy, and entropy.   A ±20% Monte Carlo stress test confirms the law’s resilience to observational uncertainty, further strengthening confidence in its validity. Together, these results transform the Diffusion of Information Hypothesis from a theoretical construct into a reproducible, data-driven framework.   This version also introduces the proposed Informational Field Principle (IFP) — the emerging hypothesis that information behaves as a universal field interacting with energy and matter. Version 13a therefore unites the ILL, the Hunt–Lyra Parameter, and the IFP into one cohesive vision: a measurable, testable, and universal description of information as a fundamental component of the cosmos.
