Kinematic Tests of Exotic Flat Cosmological Models
Abstract
Theoretical prejudice and inflationary models of the very early universe strongly favor the flat, Einsteinde Sitter model of the universe. At present the observational data conflict with this prejudice. This conflict can be resolved by considering flat models of the universe which posses a smooth component of energy density. The kinematics of such models, where the smooth component is relativistic particles, a cosmological term, a network of light strings, or fastmoving, light strings is studied in detail. The observational tests which can be used to discriminate between these models are also discussed. These tests include the magnituderedshift, lookback timeredshift, angular sizeredshift, and comoving volumeredshift diagrams and the growth of density fluctuations.
