In physics, string theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called

In physics, a Unified Field Theory (UFT) is a type of field theory that allows all fundamental forces of nature, including gravity, and all elementary

of superstring theory. Although these theories initially appeared to be very different, work by many physicists showed that the theories were related in

Classical physics refers to scientific theories in the field of physics that are non-quantum or both non-quantum and non-relativistic, depending on the

In theoretical physics, the Einstein–Cartan theory, also known as the Einstein–Cartan–Sciama–Kibble theory, is a classical theory of gravitation, one of

Alternatives to general relativity are physical theories that attempt to describe the phenomenon of gravitation in competition with Einstein's theory

referred to as non-abelian gauge theory, the usual example being the Yang–Mills theory. Many powerful theories in physics are described by Lagrangians that

particle physics theory is not solved; many theories have addressed this problem, such as loop quantum gravity, string theory and supersymmetry theory. Experimental
