Again, it should come as no surprise that many very talented people have determined that this level of understanding is important and have applied a great effort in addressing these questions.
I suggest that at this level of your learning the nature of your questions should be in the form: I am interested in (subject xyz) - can you point me in some introductory material and an overview of the state of the art. This will be the path to learning what is out there now and what questions researchers in the field are exploring.
I don’t know if you are behind the great firewall but I find that google is a very good tool to start with myself. It is amazing how fast you can “get the lay of the land” on a new topic that way.
If you don’t mind me asking; where is your home?
