Question

Define string theory and prove it using mathematical representation ​

Answer 1

Explanation:

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. String theory describes how these strings propagate through space and interact with each other. ... Thus string theory is a theory of quantum gravity.

The Hamiltonian of the closed string, provided by the quantum theory, yields a formula for the mass-squared M 2 M^2 M2 of the closed string in terms of these "number operators" [1]: M 2 = 2 α ′ ( N + N ~ − 2 ) .
