Python Computational Suite for Emergent Flatness and Dynamical Expansion in Environmental Transition Cosmology

etc-cosmo-core is an open-source Python library implementing the numerical solutions of Environmental Transition Cosmology (ETC). It provides full solver routines for background FLRW expansion under emergent Euclidean flatness (k=0k=0k=0), exact dynamical elimination of the cosmological constant (Λ≡0\Lambda \equiv 0Λ≡0), resolution of the Hubble (H0H_0H0) and growth (S8S_8S8) tensions, and galactic rotation curve evaluations without cold dark matter halos.

Abstract

etc-cosmo-core is an open-source Python library implementing the numerical solutions of Environmental Transition Cosmology (ETC). It provides full solver routines for background FLRW expansion under emergent Euclidean flatness (k=0k=0k=0), exact dynamical elimination of the cosmological constant (Λ≡0\Lambda \equiv 0Λ≡0), resolution of the Hubble (H0H_0H0) and growth (S8S_8S8) tensions, and galactic rotation curve evaluations without cold dark matter halos.
