Abstract
The study of sky background thermal radiation as a tool for probing remote outer reaches of the universe and for testing theories on cosmology, on the primeval plasma, and on isotropy of physical laws is discussed. Measurements and interpretation of antenna noise temperature, the remarkable isotropy of the background thermal spectrum, and aspects of the theory of an oscillating (expanding-contracting) universe are also dealt with. Requirements of future large-scale anisotropy measurements with greater precision are outlined. Distance determinations, from local objects to the outermost perceptible distances, are reviewed.
