Cosmology is the philosophical, religious, or scientific study of the origin, evolution (when considering scientific cosmologies), nature, and (when considering religious or spiritual cosmologies) purpose of the universe. Cosmologies answer the Big Questions.


"Cosmology (from the Greek κόσμος, kosmos "world" and -λογία, -logia "study of") is a branch of astronomy concerned with the studies of the origin and evolution of the universe, from the Big Bang to today and on into the future. It is the scientific study of the origin, evolution, and eventual fate of the universe. Physical cosmology is the scientific study of the universe's origin, its large-scale structures and dynamics, and its ultimate fate, as well as the laws of science that govern these areas."[1]
