Informational Thermodynamics

We develop a generalized framework of thermodynamics where the fundamental quantity is not energy but information. Building on the Hertault Axiom (e^4σ = Sent/SBek), Bekenstein’s entropy bound, and Hawking’s black hole thermodynamics, we formulate four Informational Laws that reduce to classical thermodynamics in appropriate limits while revealing new physics at cosmological and quantum gravitational scales. The Dark Boson emerges as the quantum of informational exchange, and the transition between dark matter and dark energy is reinterpreted as an informational phase transition. We show that black holes are maximally efficient informational engines and that the universe’s expansion is driven by informational disequilibrium. The framework provides a unified language for gravity, thermodynamics, and quantum information.
