Jim Peebles' Physical Cosmology of 1971, possibly the first book with this title, may be taken as the beginning of modern physical cosmology. Cosmology is a synonym of cosmogony. It is most closely related to the specific fields of astronomy and astrophysics, though the last century has also brought cosmology closely in … Cosmology is the discipline of science that studies the origin and eventual fate of the universe.
