It all starts with a curiosity; Before the Big Bang

There are many different interpretations about what parallel universes are, the most accepted theory is what is known as inflation, which proposes that, before the Big Bang, when the universe was neither as hot nor as dense as it is now, it already existed, but in a very different way.

Back then, it was cold and empty, although it was expanding very quickly. Then, that rapid expansion came to an end and began to slow down. Currently, many scientists believe that inflation does not stop immediately, but in small areas. So, one of these rapidly expanding areas slows down and causes a Big Bang, and that would be our part of the universe.

Then, in another area, the slowdown occurs and stops, generating another Big Bang, thus creating a different universe. This process continues, producing more Big Bangs in different universes. This is called the inflationary multiverse, which consists of a series of bubble universes, that is, an infinite number. And this could be our reality.
