What is String theory

Answer 1

String theory, in particle physics, a theory that attempts tomergequantum mechanics with Albert Einstein’s general theory of relativity.Thename string theory comes from the modeling of subatomic particlesas tiny one-dimensional “stringlike” entities rather than the more conventional approach in which they are modeled as zero-dimensional point particles.Thetheory envisionsthat a string undergoing a particular mode of vibration corresponds to a particle with definite properties such as mass and charge. In the 1980s, physicists realized that string theory had the potential to incorporate all four of nature’s forces—gravity,electromagnetism, strong force, andweak force—and all types of matter in a single quantum mechanical framework, suggesting that it might be the long-sought unified field theory. While string theory is still a vibrant area of research that is undergoing rapid development, it remains primarily a mathematical construct because it has yet to make contact with experimental observations.

Answer 2

A cosmological theory based on the existence of cosmic Strings.
