Theoretical Cosmology
Theoretical cosmology is a branch of astrophysics that seeks to understand the origins, evolution, and ultimate fate of the universe through the use of theoretical models and mathematical frameworks. Researchers in theoretical cosmology explore topics such as the Big Bang theory, dark matter, dark energy, inflation, cosmic microwave background radiation, and the formation and structure of galaxies and large-scale cosmic structures. By developing and testing theoretical models, scientists aim to uncover the fundamental principles that govern the universe on the largest scales.
