I am no expert in the string theory, but I was curious why it has so many dimensions. After thinking about it, I think I know why. It has to do with the assumption of 2-D strings. This can be understood with an analogy. We can make any color using combinations of red, blue and yellow. If we plot these three on a graph we can express all the colors on one piece of paper. If instead we assume 2-D, instead of 3-D, or only use two colors at a time, we will need three plots for the three possible two-color combinations. We will also need another plot for white and neutral gray, since these can not be made with two primary colors. Then there are the tan-grays, blue-grays, red-grays, etc., each needing their own plot. The result is an escalation in the number of dimensions. Could all the extra dimensions be a mathematical necessity due to the 2-D assumption. Based on this analogy, if strings were made more 3-D, like the single string filament that is wound inside a golfball, the result should theoretically decrease needed dimensions.(adsbygoogle = window.adsbygoogle || []).push({});
