What is the cosmology branch of astrophysics?

Im quite interested in this branch of astrophysics, i just wanted to know what exactly it involves


Thanks :)|||It is about the origin, evolution, structure and future of the (observable) universe as a whole.|||Cosmology talks about the universe as a whole. Big Bang Theory, for instance is a very important topic in cosmology, whereas the orbit of a comet is another area within astrophysics but is not cosmology.





Cosmogony is similar but concerns itself with more of the origin of the universe, though not on much on the events when time was zero or time before that since science itself has no means to address it, yet.|||Cosmology and astrophysics are two separate fields with some overlap.





Cosmologists seek an overall understanding of the universe. They try to connect the smallest fundamental particle to the observable universe and beyond with one unifying principle.





Astrophysicists are concerned with mechanisms that explain how specific objects, like supernovas and black holes function internally.
