Physicist, string theory pioneer, and excellent author Michio Kaku has written a set of guidelines called "What to Do If You Have a Proposal for the Unified Field Theory" that describes all the fundamental workings of the universe. A few of Kaku's tips:
1) Try to summarize the main idea or theme in a single paragraph. As Einstein once said, unless a theory has a simple underlying picture that the layman can understand, the theory is probably worthless…
2) If you have a serious proposal for a new physical theory, submit it to a physics journal, just as Physical Review D or Nuclear Physics B. There, it will get the referee and serious attention that it deserves.
3) Remember that your theory will receive more credibility if your theory builds on top of previous theories, rather than making claims like "Einstein was wrong!"
