Cosmic Entropy Symmetry: Unifying the Dark Sector via Holographic Thermodynamics

Here is a Zenodo-style project summary in English for the paper "Cosmic Entropy Symmetry: Unifying the Dark Sector via Holographic Thermodynamics": Description: A Unified Framework for Dark Matter and Dark Energy via the Cosmic Entropy Symmetry Hypothesis Title: Cosmic Entropy Symmetry: Unifying the Dark Sector via Holographic Thermodynamics Author: Bo Zhang (Independent Researcher) Summary: This research presents a novel theoretical framework that addresses the core crises of modern cosmology—specifically the $\Lambda$CDM model's "Hubble tension" and the unexplained physical origins of dark matter and dark energy1111. By synthesizing the holographic principle with Shannon information theory and the Landauer principle (the HSL synthesis), this paper proposes a paradigm shift: the Cosmic Entropy Symmetry Hypothesis222222222.+4 Core Theoretical Framework: The central postulate is that the total thermodynamic entropy of the universe is identically zero: $S_{total} \equiv S_{m} + S_{v} = 0$, where $S_{m}$ represents the positive entropy of matter and $S_{v}$ represents the negative entanglement entropy of vacuum geometry333333333. The Big Bang is reinterpreted as a spontaneous symmetry-breaking event that initiated the continuous dynamical interplay between these two components4444.+4 Key Findings and Mechanisms: Unification of the Dark Sector: Gravity and cosmic expansion emerge as dual mechanisms to maintain this zero-sum entropy balance5555. +1 Local Mechanism ("Dark Matter"): Gravity is a local entropic force that restores symmetry against matter-induced gradients6666. This naturally derives the MOND (Modified Newtonian Dynamics) relation in low-acceleration regimes, explaining galaxy rotation curves without the need for non-baryonic particles7777. +4 Global Mechanism ("Dark Energy"): Cosmic acceleration is a global entropic force required to preserve the holographic information bound as matter produces positive entropy over time8888. Dark energy is thus viewed as geometric pressure rather than a physical fluid9. +2 The Pivotal Scale ($a_{0}$): The research derives the critical acceleration scale $a_{0} = cH_{0}/2\pi$10101010. This scale acts as a phase boundary between local Newtonian physics and global information-thermodynamic physics11. +2 Resolution of Cosmological Issues: The framework provides a first-principles resolution to the Coincidence Problem (identifying the transition from computation-dominated to storage-dominated evolution) and refutes the "Heat Death" hypothesis in favor of a potentially cyclic cosmology12121212. +1 Observational Predictions: Hubble Tension: Predicts that $H_{0}$ is not a universal constant but depends on local entropy density, leading to systematic variations in measurements between cosmic voids and galaxy clusters13131313. +1 Dynamic Equation of State: Suggests a dynamic effective equation of state for dark energy, $w_{eff}(z)$, which correlates with the history of cosmic star formation14141414. +1 Redshift Evolution of $a_{0}$: Predicts that the characteristic acceleration scale in the Radial Acceleration Relation (RAR) evolves with cosmic time according to $a_{0}(z) = cH(z)/2\pi$15151515. +1 Significance: This work roots cosmic dynamics in fundamental laws of information and thermodynamics, offering a unified, mechanistic solution to the most pressing conceptual issues in contemporary physics16161616.+1
