Hello PF, If it isn't too much trouble, how did you guys decide what kind of research you wanted to do in graduate school? I will soon apply to graduate school yet I still don't really know what I want to do. Does this mean that I don't have a passion for physics? I really only have experience in astronomy research so I feel like getting accepted into other fields would be difficult. Also, will universities accept me if I am still unsure, or do they prefer students with concrete ambitions? Thanks for all of the help! P.S. Sorry if this is the wrong forum. I wasn't sure if this was academic or career guidance.
