The use of observable relations (kinematic information) to determine a relativistic model of the universe is examined. The relations between the apparent luminosity of distant galaxies as a function of redshift, S(z), the number of galaxies per unit solid angle up to redshift, N(z), the average cross-sectional area of a galaxy orthogonal to the line of sight, the intrinsic luminosity of a standard galxay, L(t), and the proper number density of galaxies in the past, n(t), are studied. The calculation of the expansion factor and curvature of the Robertson-Walker metric using the S(z) and N(z) combined with L(t) and n(t) is described, and the necessary equations are provided.
