The cone of the model is a 4D cone. The cone depicted in the atricle is
that of a 2D universe.
The interesting point is that at the narrow end of the cone, one of our
spatial dimention is curled up just like the extra dimentions in sting
theory..
Does the mean that space in that region is 2D not 3D?
The question them becomes... is there a point in the universe where one
or more of the curled up higher dimention of string theory "unwind".
Perhaps the ovservable univers is just a small rejion on a 11+1 D Picard
topology, where all spatial dimentions but 3 are coiled up.
physics at lower and higher dimention might be very interesting.
