there are not 11 dimentions.
There are 11 "sets" or "groups" of 11s.
HOWEVER, some are Trigonametry based, and some are Calculus based.
Some are also certain combinations of Trig and Calculus "11"s, unified with algebra "11"s.,
The resulting unified math fields, as well as the physically existing structure itself, MUST then "balance" in a "3-D frame of reference" in order for "String Theory" to become "String Fact".
I STRESS: AND I MEAN STRESS, everything as I have "explained" so far are nouns. Verbs come later.
Summing up: there are only three "measures" to consider so far; Algebra, Calculus, Trig. I STRESS: AND I MEAN STRESS those are also just nouns so far.
All string theories, like all advanced mathematics, have a 3-D "heart", or "frame of reference": where the theories begin, and where they are "propossed" to return for unification. "Unification" is ALWAYS a noun, and should never be considered a verb.
For this thread, let's state "unification" as "Big U"; the ultimate "goal" or "solution", and stop to recognize a major "brain buster" people get "confused" with.
As I read every possible theory I come across, the term: "unify", or the phrase "seeks to unify it all together" create errors in elemetary logic. Both "unifys" are verbs there.
When ANY verb is "referenced" or "defined", most people "start it up" too soon.
We are just gathering "materials" so far. We'll "start" it later.
