Abstract

This work investigates whether current geometric datasets (Pantheon+ SNe and DESI BAO) can be fitted without assuming a standard cosmic age or structure-growth history. The analysis shows that resolving the Hubble tension geometrically leads to a “cosmological trilemma,” suggesting a possible decoupling between expansion geometry and structure formation.
