I love astronomy, physics, and mathematics. For the past couple years I have been set on becoming an astrophysicist, but as of late I have been questioning the exact field of physics I would like to get into. I will preface by saying I have no prior physics classes under my belt, but understand basic principles and enjoy doing independent research on the subject. In high-school I did very well with chemistry but I want to study something a little more big picture. Science has always been intriguing to me and I would love to make a career out if it, but I am having a hard time deciding whether or not to shoot for my PhD, or aim my sights a little lower, and its also troubling to find the exact career to choose. A job that would interest me would be designing spacecrafts, but then that gets into more engineering. Another thing I would love to do is make ground breaking discoveries in creating worm holes that could one day possibly take the human race to explore Kepler-22b. Am I over-thinking things too much for someone that hasn't even started their first year of college? Or are these things that I need to worry about now? Thank you, Will Edit: I see now I have this in the wrong place, sorry.
