Is there another Universe
It is commonly believed that the universe arose as a result of the Big Bang about 13.8 billion years ago. However, some researchers believe that this hypothetical event was not the only one of its kind. It is possible that many such "explosions" occurred before. The result of such revolutionary leaps could be the formation of a multitude of universes different from that in which mankind had lived.
How many universes exist?
Three decades ago, the so-called theory of inflation began to spread in the scientific world. At the center of this concept is the notion of a special form of matter, called the "false vacuum". It has very high energy characteristics and large negative pressure. The most amazing property of a false vacuum is repulsive gravity. The space filled with such a vacuum can quickly expand in different directions.
Spontaneously arising "bubbles" of vacuum propagate at the speed of light, but practically do not collide with each other, because the space between such formations expands with the same speed. It is assumed that humanity lives in one of many such "bubbles" that are perceived as an expanding universe.
From the ordinary point of view, the multiple "bubbles" of a false vacuum are a series of other quite self-sufficient universes. The catch is that there are no direct material links between these hypothetical entities. Therefore, to move from one universe to another, alas, will not work.
Scientists conclude that the number of universes that look like "bubbles" can be infinite, and each of them without any limitations expands. In universes that never intersect with the one where the solar system is located, an infinite number of variants of the development of events are formed. Who knows, maybe in one of these "bubbles" exactly repeats the history of the Earth?
Parallel universes: hypotheses require confirmation
It is not excluded, however, that other universes, which can be conditionally called parallel, are based on completely different physical principles. Even a set of fundamental constants in the "bubbles" can differ significantly from that provided in the native universe of mankind.
It is possible that life, if it is a natural result of the development of any matter, in a parallel universe can be built on principles that are unbelievable for the earthlings. How then can the Reason be in the neighboring universes? About this so far can only be judged by science fiction writers.
It is not possible to verify the hypothesis of the existence of another universe or even a multitude of such worlds directly. Researchers are working on collecting "indirect evidence", looking for workarounds to confirm scientific assumptions. So far, scientists have only more or less convincing guesses, built on the results of studying the relic radiation, shedding light on the history of the origin of the universe.
