| contents | <h1><strong>GeNeSyS Model</strong></h1> <h3><strong>Generalized Emergent Non-Equilibrium System Yoking Substrate</strong></h3> <p>This english/french document (+ .py scripts) presents the cosmological version of the GeNeSyS model (Generalized Emergent Non-Equilibrium System Yoking Substrate), an effective framework designed to integrate memory effects, viscoelastic dissipation, and stochastic noise into the core of cosmological dynamics, within a covariant and testable setting.</p> <p>Unlike traditional approaches derived from a Lagrangian formalism, GeNeSyS adopts a non-equilibrium dynamics inspired by relativistic hydrodynamics with memory. It is built around a single effective equation (denoted (G$^\dagger$)), where appear:</p> <ul> <li>a Kelvin–Voigt viscoelastic term,</li> <li>a retarded memory variable encoding nonlocal effects,</li> <li>a Gaussian noise source representing unresolved fast degrees of freedom.</li> </ul> <p><strong>From this equation, the model aims to:</strong></p> <ul> <li>reproduce standard cosmological observables (acoustic horizon $r_s$, effective cosmological constant $\Lambda_{\rm eff}$, CMB spectra, BAO),</li> <li>provide a unified framework for several current tensions ($H_0$, value of $\Lambda$, CMB damping scales),</li> <li>deliver falsifiable signatures directly testable with present and future surveys (Planck, BAO, SH0ES, CMB-S4, Euclid, LISA).</li> </ul> <p><strong>The document includes:</strong></p> <ul> <li>a step-by-step derivation of the effective scalar and tensor dynamics,</li> <li>an analysis of dissipative effects in the high-$\ell$ CMB spectrum,</li> <li>an estimation of the slow drift of $\Lambda_{\rm eff}$ linked to memory relaxation,</li> <li>a prediction of quadratic damping of gravitational waves ($\propto k^2$),</li> <li>empirical bounds on the dissipative parameters $A_2$ (KV term in the CMB) and $\gamma_2$ (GW sector).</li> </ul> <p><strong>The text is structured into:</strong></p> <ol> <li>an introduction and the context of current cosmological tensions,</li> <li>the mathematical development of the effective equation (G$^\dagger$),</li> <li>observational constraints and numerical extractions from CMB/BAO/SN/GW data,</li> <li>a discussion of the non-Lagrangian but causal and stable framework,</li> <li>a scientific FAQ,</li> <li>detailed appendices linking the effective substrate to cosmological observables.</li> </ol> <p><strong>Note.</strong> This work remains exploratory: it does not replace the standard $\Lambda$CDM paradigm but proposes an alternative, falsifiable route.
