Astronomers are arguing about whether they can trust this untested and potentially untestable idea or not!
The universe began as a big bang and almost immediately began to expand faster than the speed of light in a growth spurt called inflation. 
 This sudden stretching smoothed out the cosmos, smearing matter and radiation equally across it like ketchup and mustard on a hamburger bun.
That expansion stopped after just a fraction of a second. But according to an idea called the “inflationary multiverse,” it continues just not in our universe where we could see it. And as it does, it spawns other universes. And even when it stops in those spaces, it continues in still others. 
This “eternal inflation” would have created an infinite number of other universes.
Together, these cosmic islands form what scientists call a “multiverse.” On each of these islands, the physical fundamentals of that universe like the charges and masses of electrons and protons and the way space expands could be different.
Cosmologists mostly study this inflationary version of the multiverse, but the strange scenario can takes other forms, as well. Imagine, for example, that the cosmos is infinite. Then the part of it that we can see the visible universe is just one of an uncountable number of other, same-sized universes that add together to make a multiverse. 
Another version, called the “Many Worlds Interpretation,” comes from quantum mechanics. Here, every time a physical particle, such as an electron, has multiple options, it takes all of them—each in a different, newly spawned universe.
But all of those other universes might be beyond our scientific reach. A Universe  contains, by definition, all of the stuff anyone inside can see, detect or probe. And because the multiverse is unreachable, physically and philosophically, astronomers may not be able to find out for sure if it exists at all.
Determining whether or not we live on one of many islands, though, isn’t just a quest for pure knowledge about the nature of the cosmos.
If the multiverse exists, the life-hosting capability of our particular universe isn’t such a mystery: An infinite number of less hospitable universes also exist. The composition of ours, then, would just be a happy coincidence.
 But we won’t know that until scientists can validate the multiverse¿
 And how they will do that¿ and if it even possible to do that, remains an open question...
Bless you!
Have a great day.
