Entropic Cosmology Outperforms ΛCDM in Observational Tests

This paper challenges the standard ΛCDM model of cosmology by proposing an entropic origin for cosmic acceleration. It uses a generalized mass-to-horizon scaling relation and entropic force to explain the observed expansion. The study's significance lies in its comprehensive observational analysis, incorporating diverse datasets like supernovae, baryon acoustic oscillations, CMB, and structure growth data. The Bayesian model comparison, which favors the entropic models, suggests a potential paradigm shift in understanding the universe's accelerating expansion, moving away from the cosmological constant.
