Hi, I don't know where to begin, please forgive me for asking this if it's been answered before. I'm confused, I don't know what to study, can you help me out? I'm fascinated by the Universe, my only regret in life is that I don't live in space far away from humans. I've always liked everything related to the Universe, but life took me to another direction. Well I'm pretty stable now, mentally, emotionally and financially, I'm 31 working in IT with a good job and good salary but lately I've been thinking about my never fulfilled fantasies and that lead me here to ask for advice. I can't remember how or why but I've been attracted to Maths lately and I always hated it in high school (irony is not lost on me). I've been watching one or two science talks/documentaries every night and I'm getting really excited about being part of that community of scientists/researchers. I know I can do it, I've done everything myself so far, but my only problem is I don't know what to study. I obviously need to study something if I want to approach this from a scientific perspective. I have some spare money, just enough to pay for a BSc degree and about 4h every day (I'm single) so I thought about going back to Uni. However, I can't figure out what is the best programme for me. Every talk I watch on WSF I see Mathematicians, Physicists, Astronomers... discuss Quantum Theory, laws of the Universe all backed by knowledge from Maths and Physics. I don't quite understand the difference. I'm aware Astronomy and Cosmology are similar and that there are elements of both Maths and Physics if you want to study either but I Astronomy courses don't have any Maths as far as I'm aware and Maths courses don't teach you anything about the Universe, so what gives? How do you combine all these fields? I'm not sure how to go about all this.
