Inflectional Friedmann-Lemaitre universes are examined, showing that current observations of graviational lenses and QSO absorption lines cannot rule out an antipode at z(a) greater than 5. Consideration is given to the expansion dynamics of a high-redshift antipode and observable properties in which a loitering universe with an antipode would differ from an Einstein-de Sitter universe. The effects produced by high-redshift antipodes are discussed, including the microwave background radiation shell, reduction of theoretical predictions for the microwave background radiation anisotropy from a combination of magnification and damping, and departure from the blackbody spectrum which may be produced by a moderately high-redshift antipode. Also, the redistribution of microwave background radiation brightness due to gravitational lensing by galaxies and cluster is studied. 40 refs.
