Hey guys and gals, I am at a bit of a stand still right now. I am a third year P.h.D. student and I have an advisor, but I am not exactly sure what area I want to research in. I went to talk to him yesterday and I said that I wanted to study General relativity, but he says that is not specific enough. What are some interesting recent developments in the field? are there any current research trends that might be viable thesis options? I am afraid if I don't decide soon then i might be asked to leave the program. Currently, my research (which up to this point was on WIMPs and dark matter) is stagnant because I have no direction.How did you all come up with thesis topics? Can someone give me an example of a P.H.D. thesis proposal? Thanks for the help.
