How many multiverses are there in the world according to physicists and astronomers

Despite great technological advances and various investigations to better understand the universe and resolve the doubts that come from previous generations, there are still many questions to be answered about this cosmos and how it works. A great unknown concerns the existence of multiverses and how many there might be.

The hypothesis that is most interesting in the scientific world, and which completely changes the panorama of everything we believed about the functioning of our universe, is the string theory. This model was proposed by scientists in the second half of the 20th century Joel Scherk AND John Henry Schwarzto explain how gravity works.

String theory and its explanation of multiverses

String theory disrupts everything we believed about the universe to give us a new perspective. To better understand this new narrative, we must forget everything we believed, like that subatomic particles they have a specific shape and they begin to imagine them as ropes.

Then photons, electrons, quarks, among others, are formed small spheres That They interact and vibrate in space. The strings of these particles have different sizes and shapes that vibrate in a certain way, but they make up everything. Vibrating and combining they give rise to the totality of existence.

The novelty of this theory is that it proposes the existence of other dimensions which we don’t know about, but it makes sense for the proper functioning of the strings. This hypothesis needs at least 10 dimensions to be developed: the four we know (one temporal and three spatial) and six compact ones that remain hidden.

It is estimated that each dimension contains from 10 to 500 universes that compose it. That is, an infinite number of universes could exist in spacetime, giving rise to the possible existence of multiverses.

This theory again it could not be proven, so it is simply a possible hypothesis about how our universe and its other dimensions work. However, the National Geographic Spain website states that this theory is the best candidate for achieving a goal unified theoryand this has not been verified why it is not falsifiable.
