Cosmology is the branch of astronomy that deals with the origin, structure, and space-time relationships of the universe. Modern cosmology is dominated by the Big Bang theory, which brings together observational astronomy and particle physics. The term is often used synonymously with cosmogony in casual conversations. A more in-depth look at the word shows that cosmology (from Greek κοσμολογία - κόσμος, kosmos, "universe"; and -λογία, -logia, "study"), in strict usage, refers to the study of the Universe in its totality as it is now (or at least as it can be observed now), and by extension, humanity's place in it. Though the word cosmology is recent (first used in 1730 in Christian Wolff's Cosmologia Generalis), the study of the universe has a long history involving science, philosophy, esotericism, and religion. (See Cosmogony for the study of origins of the Universe and Cosmography for the features of the Universe.)
