Here is the background. First of all, I am not an 18 year old without responsibility and can do anything. I have 4 children, and spent most of my young adulthood "screwing around" so-to-speak (that has NOTHING to do with the 4 kids thank-you-very-much, that came AFTER I settled down). After my divorce, I finally found I could go to school (my ex did not "allow" it) so I went, firstly, the logic route. I started my bachelors program in software engineering. As I got my brain up and running again, I remembered. How MUCH I love Astrophysics. I love Astronomy, I love physics. My free time revolves around research and self-teaching and learning everything I can about the universe and everything in it. So now, here I am about to finish my last year for my BSIT/SE, and I know that I would be a content and happy person getting my doctorate in Astrophysics. What I want to know is... is my idea stupidly wrong? I have my engineering minor as a fallback for income (4 kids, you need good income, and software engineering is GREAT income) and my future physics doctorate as my love and passion. Would I have a hard time getting into graduate school with an engineering bachelors and not one in physics? I do not want to change my minor but if I have to in order to have a life in astrophysics... well... it's a no brainer.
