String Theory

String theory corresponds to a theoretical (As the nameimplies) framework introduced in physics. This framework sharesimilarities with particle physics, as it presents point like particles(from particle physics) as one-dimensional objects, these objectsare said to be string. They are stored in the frameworkdescribed above. String theory describes the behavior of thesestrings through space. It also determines how these stringsinteract with each other. It a string is observed on a largerscale than standard string scale, it may look very similar to anyordinary particle. The particle that is being observed will holdmass, charge and other string properties that are determinedaccording t their vibrational state. Graviton is corresponded byone of many vibrational states of string theory. Graviton issimply said to be a quantum mechanical particle, which isresponsible for carrying gravitational force. According to thisstatement, it can be said that string theory focuses mainly onquantum gravity thus it is a theory of quantum gravity.The main goal of string theory is an attempt in order toaddress in-depth questions about fundamental physics. It is saidto be a broad subject that holds a wide range of concepts.Concept of black hole, cosmology, nuclear physics, matterphysics etc are some of those concepts in which string theoryis applied in order to solve a variety of questions. In the fieldof pure mathematics, many developments are carried outsuccessfully by the application of string theory. String theory issaid to be a theory for everything, since it contains descriptiveconcepts of gravity and particle physics. It literally covers allfundamental forces and concept of matter physics, which makesit a self-contained mathematical structure.Despite the theory being too much descriptive you may facecertain challenges while trying to practically apply the theory.One of the major reasons behind these problems is that thistheory does not contain a perfect definition that can be appliedin all the situations and circumstances. It becomes complicatedto develop particle physics theory based on string theory, sincestring theory describes a number of landscapes of possibleuniverses. This fact can be determined as another limitation inapplication of string theory. As a response to these limitations,many communities criticize this theory for its variousapproaches in the field of physics. Many theorists and expertsalso question about the legality of the research that is beingcontinued while using string theory as a base.
