I never understood the question that thread posed, it was like half the facts where missing...
If the Earth had a flat surface ... it doesnt
...was a perfect sphere ... it isnt
So do we get rid of gravity too, what other factors remain or are removed?
Then the diagram was so badly drawn I didnt understand what it was demonstrating.
I concluded the reasoning that answers where so evenly split was because the question wasnt clear, so i've stuck well clear.
Then of course there is the question of which mathematical model of string theory is being used (there are several, I favour a 16 dimensional model). Then we need to ask in which dimensions is the string circumnavigating the Earth, all of them or just 2 (as shown in the diagram)? If all of them, what definition do we have for the higher - undefined - dimensions?
Ultimately I am sure I would have to conclude that the string has no colour, or is polychromatic, as neither red nor blue are likely to exist in all dimensional states within an observable spectrum. Possibly even bringing us to the ultmate question of quantum mechanics: What string?
