How long is a piece of string if it's travelling at warp speed?

Well, by positing supersymmetry, superstring theory removed the faster-than-light tachyons from Bosonic string theory. The history of a string is a surface in space-time, called a "world-sheet". There are also space and time directions inside the world-sheet. So the world-sheet is like a little two-dimensional space-time, embedded in the n-dimensional space-time that the string is moving through. In the larger space-time, every point on the world-sheet has an n-dimensional position vector. So it's as if there are n fields on the string - on the world-sheet - corresponding to the space-time coordinates that the string is moving through.
