What does cosmology study?
Cosmology examines the origin, structure and development of the universe. It includes questions about Earth, the Sun, Moon, planets and stars, as well as the age and evolution of the cosmos.
Cosmology can be approached through religious story, philosophical reasoning, observation and mathematical science. These approaches often ask different kinds of questions, so comparing them requires care rather than treating every account as a scientific model.
