The interrelations between the problems of missing mass, the galactic age, and the cosmological constant Lambda are discussed. Under the assumption that the universe should have a very nearly Euclidean metric, two types of Euclidean cosmological models are considered, the standard model with Lambda = 0 and the Euclidean Friedmann-Lemaitre models with Lambda of greater than 0. It is suggested that measurements of apparent diameters of galaxies up to redshifts of 2 should aid in discriminating between the two models.
