The string realizations of point particles work only in 26 dimensions which is far from describing the four dimensions of the Universe in which we live. According to this, there are still spaces in the Standard model that should be filled by the new particles. However, there are still anomalies in this theory: First, the theory is based upon the concept of Supersymmetry meaning that as much as there are fermions there should be Bosons. When they are represented by strings, it can trace a surface and thus can explain all the probabilities of the interactions thus ignoring the infinities when describing graviton properties. If the particle is a point, it traces its trajectories which can be resembled by lines. The math describes the interactions and existence of the gravitons at the quantum level. It means that the point-like particles that we see are just the result of the excitement of strings that results in the intuitions. It is that when strings are excited gives the intuition of different particles. It can vibrate into different modes of oscillation(s): One, two three etc… It’s due to these different oscillations that one string can resemble different particles. If carefully observed through the particles with resolutions high enough, they can be viewed as one-dimensional strings that can be considered as the Planck length. The string theory is based upon the simple idea that the point particles of the standard model are just an approximation. The string theory is the collective effort of many theorists who have dedicated their lives to research and are still on the verge of its development.
