Multiverse: real or not

We have come across this concept of the multiverse in books, movies, or even heard of it. Is it possible to have a multiverse that is functioning just like our universe? The answer would be there is a possibility of a multiverse. How? Here is a video to help you understand better.

The video is nothing rocket-science to understand. Just simply stating the distance and over-all galaxies from Earth to Multiverse.

I came across this video while scrolling through youtube. It really does blow my mind into thinking that there are not only other planets but Milky ways and universes leading to Multiverse. Whether or not, one should believe in it is one’s own way of understanding. 

The video shows our milky way is not the one in the galaxy. It is joined by millions of other Milky ways. In Spirituality, people think our dreams are our gateway to other universes. How true is it? I got no idea. I know it has no proof to be real but at the same time, there is a chance for it to not be fake. 

I have nothing to explain here but only arise questions on the authenticity of the fact of Multiverse. Could it be true that our every decision is a decision made in all those other alternative universes? Could it be true that sometimes we travel to other universes through our dreams? Are all those rumours true about the people time travelling to Earth? 

Whether or not, this theory can be proved or not. There are equal chances of this theory to be fake and irrelevant  as much as it is to be true and relevant. Which side do you pick?
