I'm in high school, thinking about what I want to do in college. I am aiming to get some sort of PhD in Theoretical Physics. I would love to just get one in general theoretical physics, but I am unsure if that is offered. I know that I can go into specific areas such as particle or field theory, but I am unsure of which one I would want if a general program is not offered. I am looking to hopefully create or solve theories about "the theory of everything". I am unsure of the field that that is associated with, or if it is ultimately associated with all of it.
