An ocean of Universes

The multiverse is the set of universes, it is a very complex subject, it is fashionable now thanks to the Marvel superhero movies on Earth-616, it is the universe where the main stories take place, although there are, as you already know, countless other universes that they have arisen due to major events, changes in the timeline or other phenomena that end up triggering an alternate universe where time and the laws of nature may be different.

Those of Marvel are not the only ones who have worked with this idea, the multiverse thing is a much older idea than you may be thinking, the first reference to multiple universes comes from the medical literature of India from the year 800 to 200 Before Christ, specifically a work entitled Bhagavata Purana, which is a religious text on Krishna where he speaks of innumerable universes.

There are also some references in the literature and the term itself, the term multiverse emerged in 1895 by the psychologist William James and this term has been used in various fields, but what interests us is the field of the cosmos and the field of reality , because it is well said about the real world, the world that we know another universe outside our world would also be another reality, perhaps, it can even have different universal constant laws.

The multiverse are terms that scientists use to actually describe what is beyond the observable universe, multiverses are predicted in various scientific theories and describe different possible scenarios from regions of space on planes different from our universe, to separate bubble universes that arise and are constantly destroyed, universes where the dimensions and the laws of nature can work differently, we could see a bubble universe that is created and disintegrates in seconds although within those universes time could pass in a completely different way , extremely slow in such a way that within them tens of billions of years could have passed quietly.

In recent years, various hypotheses have been developed and there has also been much speculation about the hypothesis or explanation that is given to try to solve a problem that has the origin of the universe itself, the "problem of inflation", the origin of the big-bang .

This gave rise to the laws of nature and the universal constants, the universal constants are things like the speed of light or other constants that regulate the existence from stars to our existence with vitality, these values ​​adjust very much to the needs and measurements of the universe itself that we have, the atoms exist thanks to those constants, and the stars, the planets, and life itself exist thanks to the fact that there are a series of very precise and very specific constants for this to occur and this is quite weird.

The current theory that explains the "big band" says that this phenomenon took place 13.8 billion years ago, it was an event where the universe we know was born, but as more and more evidence is compiled and our observation of the cosmos improves, it also emerged Another problem is that it was discovered that the universe is highly uniform and homogeneous, even though it is clear that due to the great distances it is not at all clear how a thermal and dynamic equilibrium could have been produced in these dimensions and that problem was called horizon problem and to explain it the hypothesis of cosmic inflation was proposed.

One of the predictions of the theory of inflation is that it could occur again and again, perhaps infinitely, and this supposes that it would create a constellation of bubble universes, not all those bubble universes would have the same properties as in our universe they could be spaces where physics behaves differently, some of those bubble universes might be similar to our universe, but they all exist beyond the realm we can directly observe.

This would be a model of the multiverse, of the bubble universes, that of an ocean of bubble universes each with slight differences from the rest, but there are more models of the multiverse theorized by science, do you know any others? Which one is your favorite? ?.
