You might be very familiar with the Big Bang theory that says that our universe began from a single originating point and from there on, it has been expanding ever since. Within this expanding space we call the universe, exists the entirety of space, time, matter, energy, the physical laws and the constants that describe them, and all the things that we know of, can see or can’t see—it all exists in the universe. It is fascinating to think that all these things came into existence only because that point in space exploded and began expanding for some unknown reason. Anyway, my argument is not about the existence of our universe, but where does our universe exist.
It is highly debated what is beyond our universe, but no one has been able to come up with an answer that makes sense. When asked about it, well celebrated physicist and cosmologist Stephen Hawking said there can’t be anything beyond our universe if the universe came from nothing and brought everything into existence.
It makes sense, but there might be a thing that we don’t take in consideration—if the point that began the universe existed, where did it exist, in what space? It couldn’t have been under the same forces of our universe because if it did it would mean the point existed in our universe before our universe came into existence—it wouldn’t make sense. It definitely must have been under a different force.
Now, for the sake of argument, if you add the Multiverse theory here that talks about having multiple universes, maybe you can say the point existed in some other universe that we are a part of, it would make sense, but our parent universe must have existed somewhere too, where does it exist, in what space? Can universes even exist within universes that exist within universes? Maybe, but all the universes must exist somewhere, in some space. This is the Unknown Space.

In the figure above, you can see that when we put the Big Bang theory on paper, we assume a point existing in the space, where, it is not precisely defined, it’s just somewhere in the space, and with its explosion, it kept occupying the space it was in bringing everything we know into existence. Here, if you say the space the explosion created, and the space that existed before the explosion, are the same, I will disagree. As, as I said before, the point must have been under a different force that doesn’t exist within our universe. This force might be keeping our universe in its place. And if you say the universe doesn’t need any kind of force from the outside to hold it together, it itself keeps itself together, then still, it doesn’t dismiss the idea of existence of a space beyond our universe. The unknown space exists and our universe keeps occupying this unknown space. We yet can’t consider the existence of this unknown space because we have accepted that everything that we know and see in our universe is all there is, plus, we can’t imagine the unimaginable.
I’m strongly saying there must be a space out of our universe because this space could be the answer to our higher form of existence. If only we can understand what this unknown space is and how it functions, we might be able to understand a force greater than the forces that exist in our universe. And if we can somehow learn to have access and control over this unknown space, we might be able to travel through universes, or maybe through dimensions. The mystery of this unknown space is what is keeping us bound to this universe of ours. If only we can figure this unknown space out, we might reach a new level of our existence.
