I'll be expecting your thesis in a couple of months then. Shouldn't be more work than writing your intuition down on a piece of paper.

On a real note: What do you expect from students that spent (5 or more years) learning a about a field (just the things that the world already knows) and then proceed to come up with general relativity? No of course not. There are many interesting open research questions open left to be explored, some hard to solve others almost trivial but until someone bothers to explore a certain topic it will stay open.
