Are strings really just one dimensional? Is it possible that strings are 3 dimensional? Or even 10 dimensional?
but what if they are like a string like a string on a guitar which has 3 dimensionsandrewkirk said:If they had more than one dimension, they would not be called strings.
There is something called 'brane theory' (brane is short for membrane) that has big membranes wobbling around in a many-dimensional manifold, with exciting things happening when they touch. In common language, a membrane is two-dimensional. So I imagine Branes have two dimensions, although it could be 'two or more'.
A "string" on a guitar is not a string in that sense, BECAUSE it is 3D. It is a tube with length, breath, and height, not a stringNav said:but what if they are like a string like a string on a guitar which has 3 dimensions
Nav said:Is it possible that strings are higher dimensional branes but are just more compacted to seem like they are one dimensional when in reality they are more?

rootone said:Or even 24 dimensional, that works too.
Have to remember that string theory is not as yet supported by evidence, though a lot of people like the idea.
haushofer said:You end up with branes, and as far as I know the action of such a brane is not renormalizable, and we don't know how to write a Polyakov-like action like we know for strings. I'm also not sure how you could quantize such an action.
