Calabi-Yau Manifold Crystal
According to string theory, space-time is not four-dimensional as you might expect, but actually 10-dimensional. The extra six dimensions are believed to be compactified or rolled up into such a small space that they are unobservable at human scales of sight….
Their size and six dimensions make Calabi-Yau spaces difficult to draw. But, this model shows a three-dimensional cross-section of this likely space to reveal its structure and shape. – Scientifics Online
And all that mind-bending fun is just $90! String theory, in the palm of your hand! Or, if you don’t subscribe to string theory, it’s a paperweight.
