a theoretical framework

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

a model of physics

String theory is a model of physics where all "particles" that make up matter are composed of strings (measuring at the Planck length) that exist in an 11-dimensional

a branch of theoretical physics that studies the dynamics of interaction not of point particles

String theory is a branch of theoretical physics that studies the dynamics of interaction not of point particles, but of one-dimensional extended objects, the so-called quantum strings.

a hypothesis for the unification of general relativity and quantum theory

String theory is a hypothesis for the unification of general relativity and quantum theory; but since quantum theory has not yet provided an explanation of the standard model of particle physics that is hard to vary, the hypothesis is regularly questioned.
