Geometric interpretation of the dark energy from projected hyperconical universes. Physical Review D, 98(4), 043508.This paper explores the derivation of dark energy from a locally conformal projection of hyperconical universes. It focuses on the analysis of theoretical compatibility between the intrinsic view of the standard cosmology and an adequate transformation of hyperconical manifolds. Choosing some parametric family of locally conformal transformations and taking regional (second order) equality between the Hubble parameter of both theories, it is predicted that the dark energy density is ΩΛ =0.6937181 (2). In particular, we used a radially distorted stereographic projection, the distortion parameter of which is theoretically predicted about α =0.325+-0.005 and empirically fitted as α=0.36+-0.02 (χ20 =562) according to 580 SNe Ia observations.engAtribución 3.0 Españahttps://creativecommons.org/licenses/by/3.0/es/journal articlehttps://doi.org/10.1103/PhysRevD.98.043508https://journals.aps.org/prd/abstract/10.1103/PhysRevD.98.043508open access524.8Cosmological constantDark energyDark matterEvolution of the UniverseRelativistic aspects of cosmologyAstrofísicaAstronomía (Física)Geometría1204 Geometría
