String theory corresponds to a theoretical (As the name
implies) framework introduced in physics. This framework share
similarities with particle physics, as it presents point like particles
(from particle physics) as one-dimensional objects, these objects
are said to be string. They are stored in the framework
described above. String theory describes the behavior of these
strings through space. It also determines how these strings
interact with each other. It a string is observed on a larger
scale than standard string scale, it may look very similar to any
ordinary particle. The particle that is being observed will hold
mass, charge and other string properties that are determined
according t their vibrational state. Graviton is corresponded by
one of many vibrational states of string theory. Graviton is
simply said to be a quantum mechanical particle, which is
responsible for carrying gravitational force. According to this
statement, it can be said that string theory focuses mainly on
quantum gravity thus it is a theory of quantum gravity.
The main goal of string theory is an attempt in order to
address in-depth questions about fundamental physics. It is said
to be a broad subject that holds a wide range of concepts.
Concept of black hole, cosmology, nuclear physics, matter
physics etc are some of those concepts in which string theory
is applied in order to solve a variety of questions. In the field
of pure mathematics, many developments are carried out
successfully by the application of string theory. String theory is
said to be a theory for everything, since it contains descriptive
concepts of gravity and particle physics. It literally covers all
fundamental forces and concept of matter physics, which makes
it a self-contained mathematical structure.
Despite the theory being too much descriptive you may face
certain challenges while trying to practically apply the theory.
One of the major reasons behind these problems is that this
theory does not contain a perfect definition that can be applied
in all the situations and circumstances. It becomes complicated
to develop particle physics theory based on string theory, since
string theory describes a number of landscapes of possible
universes. This fact can be determined as another limitation in
application of string theory. As a response to these limitations,
many communities criticize this theory for its various
approaches in the field of physics. Many theorists and experts
also question about the legality of the research that is being
continued while using string theory as a base.
