COSMOLOGY IN A STRING-DOMINATED UNIVERSE

The string-dominated universe is a flat universe that locally resemble s an open universe and Bts dynamical measures of power spectra, cluste r abundances, redshift distortions, lensing constraints, luminosity, a ngular diameter distance relations, and microwave background observati ons. We show examples of networks that might give rise to recent strin g-domination when formed by a phase transition near the electro-weak s ymmetry breaking scale. We discuss how future observations can disting uish this model from other cosmologies.
