Several speculative physical theories have introduced extra dimensions of space for various reasons:
* Kaluza-Klein theory introduces extra dimensions to explain the fundamental forces other than gravity (originally only electromagnetism).
* Large extra dimensions and the Randall–Sundrum model attempt to explain the weakness of gravity. This is also a feature of brane cosmology.
* The extra dimensions in superstring theory are required for mathematical consistency and are often assumed to have the shape of a Calabi–Yau manifold.
