What is theoretical astrophysics?

Theoretical astrophysics employs the laws of quantum physics and chemistry in order to understand the internal structure of various objects in the universe. It employs a variety of theoretical tools, such as analytical and numerical models in order to compromise the results obtained from the experimental data and the theoretical predictions.

Several interesting topics are examined in theoretical astrophysics including galaxy formation and spinning effect, star creation and collapse, the impact of general relativity theory in the universe as well as the practical implication of string theory (i.e. black holes, event horizon). The Bing Bang conjecture is a famous theory that has been created from theoretical astrophysicists.
