does anyone understand string theory?

I got a book about String Theory...but haven't got to it XDD (bought it with my own money at Barnes & Nobles). Its about sub-sub-subatomic strings (smaller than quarks and electrons). Often called "the theory of everything" because it would unify all the other theories. But no, I don't understand what string theory is unless I pay attention to my own book (the theory has not been proven yet and little is known; I probably wouldn't get it then).

Of curse I do!
It's the theory that Earth is held up bởi strings! Duh!
