The different physical conceptions of the cosmological constant have been analysed, as well as the relation of the cosmological constant with the vacuum energy, whose discrepancy is considered the one veritable crisis remaining in physics5 p.application/pdfengcc-by-nc-nd (c) Gil, 2024http://creativecommons.org/licenses/by-nc-nd/3.0/es/CosmologiaEquacions de camp d'EinsteinTreballs de fi de grauCosmologyEinstein field equationsBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
