According to string theory, spacetime as we know it isn't 4-dimensional, but 10-dimensional. The next question is, where are the extra 6 dimensions that we don't see? One answer is that they're 'compactified': roughly speaking, rolled up into such a small shape that they're unobservable by humans.
Calabi-Yau spaces may be that submicroscopic shape. There are many such spaces, but being 6-dimensional, they're not easy to draw! This model is a 3D cross-section through a likely space. Surprisingly it's beautiful – a wildly self-intersecting ride.

Hi! Maybe you came here from the MSNBC CosmicLog blog? Good news: our supplier has stepped up and we have the Calabi-Yau cubes in stock. Check here for Christmas ship deadlines. Bad news: we're out of the light bases, they're backordered until probably mid-January. We won't delay the rest of your order to wait for a base (unless you ask), and when they come in we'll ship them at no extra cost to you. Thanks for coming! |
Calabi-Yau Manifold, 80mm glass cube – $72

Without illumination the crystal works best on a dark background. It comes with clear rubber feet to avoid scratching your desk or mantel. On the left, this light base is a great way to light up your manifold! It's made of black Formica and has white LEDs that are cool, long-lasting and energy-efficient. Bright enough for the office by day, or a brilliant nightlight. |
