The mathematics that model memory and the mathematics of string theory would seem to indicate that there are 11 dimensions. But there are belief systems and philosophical models, both ancient and contemporary, which propose that there are 12 dimensions. However there seems to be no scientific support for this, other than, perhaps, the shape of the universe.
If such a dimension exists, what would it look like? Why is the presence of a 12th dimension not clear in those formulae and models which would suggest that there are at least 11 dimensions? I would propose that the answer to that question is that the 12th dimension presents us with a seldom used value, and that value is ∀.
The twelfth dimension is the dimension where all the other dimensions intersect. It can’t be measured because the value of the 12th dimension is always ∀, or “all”.
This understanding of the 12 dimensions explains various puzzles in quantum physics. How it is possible for a particle to exist in every possible random location until the probability wave is collapsed? How is “spooky action at a distance”, a.k.a. quantum entanglement, possible? The answer is that any particle which manifests in the 12th dimension will have the same “value” in that dimension as every other particle which manifests in that dimension.
There are theories in physics which support the idea that the universe has 12 dimensions. If you have a universe where only three dimensions exist, and you give the limits of each axis positive and negative values approaching infinity, the shape of that universe will be a cube. If you have a universe where there are 12 dimensions, and you assign a value for the limits of each axis to approach infinity, for both positive and negative values, it’s “shape” will be a dodecahedron. Interestingly enough, this is the shape of the universe that recent advances in physics are suggesting.
