SharePhysical cosmology, as a branch of astrophysics, is the study of the large-scale structure of the universe and is concerned with fundamental questions about its formation and evolution.

Cosmology involves itself with studying the motions of the celestial bodies and the first cause.
Physical cosmology, as it is now understood, began with the twentieth century development of Albert Einstein's theory of general relativity and detailed astronomical observations of extremely distant objects.
