Answer 2

Answer:

A cosmological theory based on the existence of cosmic strings.

Explanation:

String Theory, in relation with particle physics is a theory that attempts to merge quantum mechanic with Albert Einstein's general theory of relativity. The name string theory comes from the modeling of subatomic particles as tiny one-dimensional “stringlike” entities rather than the more conventional approach in which they are modeled as zero-dimensional point particles. The theory envisions that a string undergoing a particular mode of vibration corresponds to a particle with definite properties such as mass and charge.
