I'm not a theoretical physicist and only took a few math courses beyond which were required by my major, but it was my understanding that mainstream string theories have 10, 11, and 26 dimensions, but I recall, and could be wrong, that there can be infinitely many string theories with 4 dimensions being the lower bound and some unspecified upper bound. But I'm not an expert and I was mostly being hyperbolic with my original reply. Corrections are always welcome. |
