Detailed explanation-1: -cosmogony, in astronomy, study of the evolutionary behaviour of the universe and the origin of its characteristic features. For scientific theories on the unsolved problem of the origin of the solar system, see planetesimal; protoplanet; solar nebula.

Detailed explanation-2: -Cosmology is the study of the structure and changes in the present universe, while the scientific field of cosmogony is concerned with the origin of the universe.

Detailed explanation-4: -Physical cosmology is the branch of physics and astrophysics that deals with the study of the physical origins and evolution of the universe. It also includes the study of the nature of the universe on a large scale. In its earliest form, it was what is now known as “celestial mechanics", the study of the heavens.

Detailed explanation-5: -cosmology, field of study that brings together the natural sciences, particularly astronomy and physics, in a joint effort to understand the physical universe as a unified whole.
