Hi there, I'm in my final 2 years in high school studying mathematics, physics, further mathematics and chemistry. I'll be applying to universities next winter. But, here in the UK, there're courses for physics in the uni titled: Physics with Theoretical Physics or Physics with Astrophysics. And I'm not really sure which to apply to in order to be able to go into cosmology research in the future. I've a strong inclination to the relationship between physics and maths as well as the study of stars and the observable objects in the universe. And I'm really confused which to decide with. Can someone clarify to me more what cosmology is and which degree of those shall be more preferable to a cosmologist?
