After the recent sensational announcement of the potential discovery of the first signs of the presence of gravitational waves in space, which left their imprint in the relic radiation of the Universe, serious passions flare up among the international scientific community. So a group of theoretical physicists believes that the new discovery gives the right to support the theory of the Multiverse.
The essence of the Multiverse theory, if anyone does not know, is the hypothesis that our Universe (that is, the one in which we live) is not the only, but only one of the almost infinite number of other Universes united into one indescribable giant Multiverse. And this theory in fact may not be as far-fetched as it may seem at first glance. One of the theories of the Multiverse tells us that the almost instantaneous expansion that the Universe experienced in the first split second (that same cosmic inflation) after the Big Bang was uneven.
As a result of the Big Bang, the expansion of some parts of space-time could happen faster than in others. This effect in turn could create space-time “bubbles”, which in turn would develop into other Universes. Detection of gravitational waves without a doubt can say that the Big Bang really was, and after the first fraction of a second after it began, the process of cosmic inflation, or a rapid (almost instantaneous) expansion of space-time, started.
The gravitational waves themselves, as scientists believe, in space-time were formed by this inflation. And although the theory of the expansion of the Universe has existed for more than a decade, direct evidence of the existence of inflation, which occurred in the first fraction of a second after the Big Bang, could not be detected by scientists. What is even more interesting is that scientists are confident that the rate of inflation of the cosmos itself was several times higher than the speed of light itself.
The idea of the Multiverse suggests that each individual Universe that is present in it has its own set of physical rules, although it does not exclude the possibility that some of them (Universes) share these rules.
“It is difficult to build any of the space inflation models that would not ultimately lead to the Multiverse theory. I think it is just impossible. Most likely, scientists will still have something to smash their heads in the near future, ”says Alan Gat.
An expert in theoretical physics from the Massachusetts Technical Institute did not participate in the detection of gravitational waves, but during a conference that took place yesterday, the physicist stated that “most inflation models lead to the principles of the Multiverse and proof of inflation each time will lead us to that in the end we will have to take the Multiverse theory seriously. ”
Andrei Linde, a theoretical physicist at Stanford University, known to the scientific community for his theories of constant inflation and the Universe inflation model, agrees with his colleague from MIT and believes that there is a very strong connection between the Multiverse theory and inflation.
“In most models of inflation, there is actually inflation itself and the Multiverse model. Of course, there is indeed an opportunity to create inflation models that would not contain the Multiverse model, but this is a very, very difficult task. Each experiment aimed at finding evidence of the existence of inflation in one way or another, in one way or another, leads us to believe that the Multiverse is really real, ”the expert says and agrees with her colleague Gath of MIT.
