You mentioned a divergence from time lines. How is it possible to measure such a divergence? I would assume that it would be impossible to calculate how causes of one single event would propagte into the future. Does not chaos theory make such determinations impossible? Even if I gave you the exact position and velocity of all objects in the universe (which is impossible(I can not even give you the exact position and velocity of a single object due to the Heisenberg Uncertainity Principle)) you could not tell me what the future holds. Of course this results from the fact that the objects do not represent individual closed systems but in fact can interact.
You said 6 curled up dimensions. The current theory suggests that there should be at least 7 curled up dimensions. It was discovered by Ed Witten that if you added an additional dimension that the 5 slightly different versions of string theory would combine into a single theory, which is often called M-theory.
