The Cosmological Constant Kinematics II Basic Idea: Equation for expansion of universe gives information about history through various classical cosmological tests. Emphasis here is on how the expansion affects observational phenomena. metric and spatial curvature equations of motion in terms of cosmological parameters a(t) determines many properties Age: H0 and lambda Combined with properties of light: redshift and null geodesics provides distance as function of redshift and parameters. path length angular diameter distance/ luminosity distance volume Some references.
