The numerical values Omega_Lambda = 0.737 (dark energy), Omega_M = 0.263 (matter) which determine today's concordance (consensus) model essentially, are deduced from a purely relativistic one-parameter model of a stationary universe. To that end the line element of a spatially Euclidean universe is given in a general scalar form ds = zeta*ds_SRT, as fixed by the requirement of a constant intergalactic speed of light c* = c (postulate I). With the special assignment zeta = exp(Ht*) this leads to a stationary cosmological solution of general relativity theory (postulate II). Therein, for galaxies statistically at rest, the redshift parameter z = exp(Hr*/c) - 1 is independent of time. Already by itself, this model is near the observational facts. Now, an evolutionary cosmos is distinguished from the embedding universe. The cosmological constant Lambda is used to describe this cosmos heuristically. Finally the 'constant' Lambda, fitted straightforwardly from the stationary universe, meets today's concordance model almost perfectly.
