Scientific paper

Spectra are calculated for the primordial adiabatic perturbations and the gravitational waves that would develop in the author's 1980 model of a nonsingular cosmology with an initial de Sitter quantum stage resulting from gravitational vacuum polarization. The gravitational-wave spectrum will be flat; the adiabatic-perturbation spectrum, nearly so. In that event, the most promising way to detect large-scale temperature anisotropy in the cosmic microwave background would be to measure Delta-T/T correlations over 5-10 deg angles.
