The Large-Scale Structure of the Universe
Across blllions of light-years space is a honeycomb of galactic superclusters and huge voids. The structure may result from perturbations in the density of matter early in the big bang

The Structure of the Early Universe
The large-scale structure of the universe today is regular to within one part in 1,000. There is evidence that it has been that way since 10-35 second after the start of the big bang

The Origin of Galaxies
The size, shape and other properties of the observed galaxies are traced to slight density enhancements in the expanding primordial fireball. Enhancements of certain mass were favored over others
