Theology is the systematic and rational study of religion and its influences and the nature of religious truths, or the learned profession acquired by completing specialized training in religious students, usually at university or school of divinity or seminary.
Augustine of Hippo defined the Latin equivalent, Theologia, as “reasoning or discussion concerning the Deity”; Richard Hooker defined “theology” in English as “the science of things divine.”

Cosmology is the discipline that deals with the nature of the Universe as a whole. Cosmologists seek to understand the origin, evolution, structure, and ultimate fate of the Universe at large, as well as the natural laws that keep it in order. Modern cosmology is dominated by the Big Bang theory, which brings together observational astronomy and particle physics.
