String theory is an attempt at a deeper description of nature by thinking of an elementary particle not as a little point but as a little loop of vibrating string. Part of the process of evaluating the path integral in our quantum gravity model is to integrate over the metric on the onemanifold, modulo diffeomorphisms.
