Greetings. My question comes in two parts.(adsbygoogle = window.adsbygoogle || []).push({});

Part one - In most "low-level - made for t.v." explanations of the extra dimensional space they describe these extra dimensions as "curled-up". If I were to visualize the extra dimensions of string theory would it be better to think of these extra dimensions as having their "end points" connected to the endpoints of our visible 3 linear dimensions (Lets just say there is endpoints for sake of discussion) yet their "length" in comparison to the 3(X,Y,Z) is very,very small. My other idea for visualization would be something like a infinite spiral such as that of a Mandelbrot set.

Part two - Are these dimensions spatial like our 3(X,Y,Z) or more 'exotic' like space/time in the String Theory models? Or do some groups of thought consider them a sort of 'placeholder' to keep the Theory 'stable'?

-Thanks in Advance
