Importance of String Theory

Theoretical physicists try to create general models or theories that group the different forces that govern the universe. It is a conceptual necessity to understand the universe as a whole. The most advanced proposal in this regard is precisely String Theory.

It is not an absolutely endorsed conception and with its corresponding confirmations. experimental, since there is a possibility that said theory does not correspond to the truth of the facts.

On the other hand, this contribution is simply a theoretical framework or paradigm that encompasses a series of beginning.

General principles

In 1968 an Italian physicist at CERN named Gabriele Veneziano observed that the strong force that binds the protons and neutrons in the nucleus of the atom can be explained with an equation math 200 years that had already been formulated. With this old equation it is already possible to affirm that all the particles of the universe are united by filaments of subject, that is, some strings.

The strings vibrate in such a way that the particles we know are generated (basically protons, neutrons and electrons). This theoretical view became popular in the 1980s.

With the new paradigm, all the particles in the universe are understood from the vibration of a single fundamental element, the strings. The type of vibration of the same causes one behavior or another in the state of matter.

In a language colloquially it could be said that these filaments are like the strings of a violin, which produce one or another musical note depending on how they move. In this way, the way of understanding the universe has been simplified in a very significant way.

A scientific model that allows to unify the theory of relativity and quantum physics

String Theory has become a general formulation or Theory of Everything. Thus, it is possible to describe within the same framework any phenomenon in the universe, from the movements of subatomic particles to the movements of planets.

Despite the progress in explaining the laws of the universe, this theory has some limitations or weaknesses. For one thing, strings are infinitely tiny and are billions of times smaller than a proton. This means that the only way to perceive these particles is through a collider specifically designed for this purpose. This means that to see a string, a particle accelerator as large as the solar system itself would be necessary.

On the other hand, for the theory to make full sense it would be necessary for reality to have a total of eleven dimensions, which in turn means that there are several dimensions that we do not see or know but that we do exist.

In short, from String Theory we have an explanation of the mechanisms of the universe, but the proposal has not yet been fully developed.
