Can you steer me in the right direction for my graduation project?

A requirement for me to graduate is to do a graduation project, so I decided I wanted to do it on something I’m incredibly interested in: astrophysics. I want to do my project on something in that area, whether it deals with the universe, physics, or people like Einstein and Newton. I just can’t think of a question to do it on. The question has to be broad because I need to write a whole research paper about it.

Could anyone help steer me in the right direction? I’m not asking for a direct question, just a little help to get me started.
