The direction of theoretical physics that studies the dynamics of the connections are not point particles and the one-dimensional comprehensive objects, the so-called quantum strings. String theory combines the ideas of quantum mechanics and relativity theory, therefore, based on it, may be to build a future theory of quantum gravity.
String theory is based on the hypothesis that all elementary particles and their fundamental interactions are the result of vibrations and interactions ultramicroscopic quantum strings on the scales of the order of the Planck length 10 -35 m. This approach, on the one hand, to avoid such difficulties, quantum field theory, a renormalization, on the other hand, leads to a deeper view of the structure of matter and space-time.
