Hi, so I was initially planning on becoming a geologist, the subject does interest me but a major motivation for this was of course the money. Anyways I would always try to squeeze in astronomy classes as my electives and would spend a lot of time reading and watching documentaries about astronomy and physics. So when my room mate asked why I wasn't doing a minor in physics or astronomy, it kind of set of a spark in my mind and I went even further and decided I would major in it. Being quite far into a geology degree the only reasonable option was to do a geophysics degree. Sorry for the long background story, here is the real question. So I know that geophysics is an excellent degree to have in terms of getting a job. However if I did decide to go to grad school, I just could not see myself enjoying geophysics. My passion is definitely more in the field of astronomy and "traditional" physics (not sure how to describe that, I think you all get what I mean though). I was just wondering if it is possible to make this shift when getting into grad school?
