## Main Question or Discussion Point

Is it just me, or are dimensions supposed to simply add another coordinate, i.e., I can move 1m in x, y or z direction and be 1m away from where I started, are the dimensions in string theory based on this concept or do I not understand what a dimension is? The most confusing part is how these dimensions are supposedly rolled up and small, why are they now being treated like manipulable entities?

Also, another poster stated that there are conjectures which say that, given enough energy, a string can leap to another dimension, if each dimension simply represents a coordinate that every material entity has, then why would this make any sense at all?

I know I must have a fundamental misunderstanding somewhere, can anyone explain what dimensions are really considered to be, and how any of these ideas are possible? Thank you
