Also understand how different phenomena of nature, from small elementary particles and fundamental forces right up to very large scale structures in the universe such as clusters of galaxies, all fit together. When first started, it was estimated the universe was 9-25 billion years old. If the universe is infinite and static, then at any given angle from the earth the line of sight will end at the surface of a star. All matter, space and time were compressed into an infinitely small space known as a singularity. Prevailing theory of the early development of the universe.
