Cosmology
Cosmology is a branch of astronomy that relates to the origin of the Universe, its evolution and eventual fate. It covers a broad variety of topics from string theory to dark matter, and cosmologists work to both broaden and refine our understanding of the current model of the Universe: The Big Bang Theory. With ties to physics, philosophy and ancient history, cosmology is an expansive subject that aims to discover the true theory of everything.
