Visualizing seven extra dimensions

[shatteredligh]

Hi, I am a sculptor working with glass. I have come to this forum for some information.

Several years ago I read an article on sting/M-theory that gave a description of one of the possible shapes the the 7 compact extra dimensions of m-theory. I have been unable to find the article again. I shall do my best to remember the description.

It was something like: 3 curled up dimensions surrounding another 3 curled up dimensions somewhat like a russian doll. These two "sets" of dimensions are somehow separated yet a strange straw-like dimension stretches between between these two "sets", making a total of seven extra compact dimension rolled up into a plank sized nugget.

Does this mean anything to anyone.
I am interested to make my next project a representation of this preposed shape.

I would appreciate any information, the name of this structure, web references etc.

I am also curious as to how a straw like dimension could represent only one dimension.

Thanks Dave.

This is what the shape is: http://en.wikipedia.org/wiki/Calabi–Yau_manifold, but your description is different. The extra-dimensions in M-theory are compactified on a G2-manifold: http://en.wikipedia.org/wiki/G2_manifold.
