Hello all, This is my issue. I did my undergrad in Physics. After finishing I decided I was done with "pure" physics. I wanted to do something more practical so I went into a Masters in Medical Physics. I quickly realized, that although I don't find it un-interesting, I don't feel much of passion for the field of clinical Medical Physics. As part of my degree I have to do research as well and I'm now doing research in a lab which really interests me. I really like the subject, and I really like the group. (It's not in clinical medical physics, it's more so part of Biomedical Engineering) However, I'm no longer doing something "practical", I'm back to research. Which, if I like, then why not do it in Physics, which was my passion to begin with? I've always been very passionate about Astrophysics but never wanted to go into it because I though I didn't want to do research. But that's what I'm doing now anyway. So I'm thinking of switching into a PhD in Astrophysics and going back to my first love, so to speak. What do you all think? Do I stand a chance? Is it way too random to go from Medical Physics to Astrophysics? And is it too big a risk to leave a place I like, and could very well continue in to do my PhD, for something unknown? I feel like if I go on as things are, I'll be happy, but I'll always feel like I didn't pursue my original dream of doing Astrophysics... Is it a complete handicap that I don't have a Masters in Astrophysics? Thanks in advance for any advice/insights that you might be able to give me!
