- There is, in fact, some work on "membrane theory," the higher dimensional
- generalization of string theory. In general, membranes don't work very
- well for particle physics purposes. For instance, strings have a
- discrete energy spectrum, yielding particle-like excitations of
- different masses; membranes typically have a continuous spectrum,
- and would lead to a continuous range of particle masses.

- There may now be ways of fixing this --- I'm not up on the most
- recent literature.
