Re:String Theory (Score 5, Insightful)

The issue isn't the inability to understand higher dimensions, most critics have an issue with the inability to observe higher dimensions. If higher dimensions exist, why don't we observe things moving in them? The only reason String theory predicts higher dimensions is because the matrix it uses (the math kind not the movie kind ;-) can only be solved in higher dimensions. So the explanation that these higher dimensions must in fact exist on a plane smaller than our observable limit (roughly a proton) seems a bit arbitrary to some (many).

Surely we can agree that the gap between quantum and relativity needs to be filled, but going off on a whole set of random assumptions based on what needs to be true to solve a little math issue might not be the best approach. Then again, look what it did for Einstein... Of course the difference there was that his predictions were actually observed...
