Multiverse Theories

The multiverse is a global concept, which encompasses other theories, which talk about alternative universes, parallel universes or multiverses and there are possibilities of universes compatible with each other, that is, we could be living in a multiverse that also had other multiverses on other scales. cosmic

Brian Greene, who is an American mathematical theoretical physicist and string theorist or stringer as some say, has made a popular science series and is quite well known. This theorist organizes multiverses into several categories, into inflationary multiverse, cyclical multiverse, self-producing multiverse, multiverse. brane, landscape multiverse and holographic multiverse and I say that this would only be one of the options of how to organize them and only some of the theories how to develop the theme of multiverses.

Although it seems like science fiction, this is science and although it seems almost philosophical or mystical, they are theories that, although we cannot yet prove them because in recent years very interesting experimental proposals have been made that many scientists and theorists develop and study, although the first concepts that They are born from philosophy and religion.

The first concept of multiverse and the oldest is the cyclic universe or cyclic universes, this concept was born, unless we have reference to it, about 2,500 years ago in ancient Greece, there the wise Heraclitus stated that the universe was born from fire and perished in fire in an infinite cycle, that cycle lasted exactly 25,776 years, which is known as the great year or Platonic year.

The cycle measured the complete rotation of the axis of rotation of the earth around the current North Pole of the cryptic, in Greece at the same time there were also the atomists whose main wise man was Democritus, of whom unfortunately we do not preserve any of his works. , but we have very interesting references and quotes.

Democritus and his followers maintained that originally the universe was composed only of small atoms that churned in chaos until they collided with each other to form larger units, including the earth and everything that inhabits it, he assumed that there were many worlds, some growing others dying, some without sun and without moon.

Practically from the same time are the first writings in India where they speak of infinite time with a cyclical universe, where the current universe was preceded and will be followed by an infinite number of universes, it is possible that these ideas are previous and it is also It is possible, at least I believe it, that the existence of infinite cyclical universes that are born and end up destroyed in an apocalypse, occurred in an ancient common focus and then will be transmitted through the different trade routes between East and West, because it is a It is not strange that at the same time in Greece and India such similar ideas arose.

When theorists make a theory they also try to design experiments to demonstrate it, because at the end of the day theories try to explain a reality and of course what counts is reality, it is the evidence that must be sought, evidence to confirm that theory until it is confirmed. that theory with the evidence and with reality that theory is still up in the air.
