In the field of theoretical physics, attempts are made to understand the universe and for this, physicists resort to mathematical formulas. One of the questions that arises is the following: how did the universe come to be? This question is equivalent to asking how everything began and for this reason we speak of the theory of everything.

The definitive mathematical formula that explains the origin of the universe does not yet exist.

## Looking for the equation that explains the universe

One of the problems when it comes to finding an explanation for the universe is presented again in the form of a question: can human beings get to know the origin of the universe?

The fact of discovering the expansion of the universe from the explosion generated in the big-bang has been fundamental to understanding the origin of the universe, but such progress has not been translated into a specific mathematical formula. In this sense, the formula of general relativity expressed by Albert Einstein affirms that where there is mass and energy there is a distortion of space and time.

## Einstein’s advances on the relationship between mass, energy and space-time were complemented by another theoretical physicist, Stephen Hawking.

According to Hawking, the big-bang is directly related to black holes. Thus, if it were possible to calculate what the center of a black hole is, one could also calculate the moment in which the universe arose.

In the search for the Theory of Everything, some theoretical physicists propose to unify the theory of general relativity with the explanatory models of the most elementary particles, which are integrated into the field of quantum physics.

In other words, it is proposed to create an explanation that combines the micromatter of the universe with space-time. This new course of theoretical physics was proposed by the self-taught Russian scientist Matvei Petrovich Bronstein. This scientist took as a reference some particles in microscopic space and tried to understand how the law of gravity intervened in such particles.

He came to the following conclusion: the microscopic world and gravity can be unified in a mathematical equation.

## Superstring theory is the new paradigm of the Theory of Everything

According to superstring theory, before the creation of the universe, there was a world of elementary particles that were fluttering like moving strings.

This paradigm of theoretical physics proposes a new combination between elementary particles and the general theory of gravity. The search for a mathematical formula that explains everything implies understanding the smallest (atoms) and the largest (galaxies).

According to the proposal, both matter and energy in the universe are made up of a single element: tiny filaments of vibrating energy known as strings. This theory states that the particles into which atoms are divided (quarks) are made up of oscillating strings of energy that are similar to moving strings.

In other words, the type of movement of the strings is what generates the mass and electric charge of the different particles. For this model to make sense, theoretical physics must contemplate a universe made up of ten dimensions and not the traditional four, which means affirming that there are parallel universes that are in the same place as our universe, but in another dimension.
