The science of the origin and development of the universe. The study of the universe as a whole, including its structure, evolution, and ultimate fate.
From Greek kosmos (universe, order) and logos (study, word). Coined in the 17th century as natural philosophy began separating into distinct sciences, combining ancient Greek concepts of cosmic order with systematic study.
Ancient Greek kosmos originally meant 'order' or 'ornament' - the universe was seen as beautifully ordered rather than chaotic. This aesthetic dimension of cosmic study persists today when physicists speak of 'elegant' theories.
