There aren't any definitive equations of string theory AFAICT. For the Standard Model, there are. This is on top of the lack of rigour that's already in QFT. T

There aren't any definitive equations of string theory AFAICT. For the Standard Model, there are. This is on top of the lack of rigour that's already in QFT. The result is a theory that isn't really mathematics as mathematicians understand it, and nor is it physics as many physicists understand it.
