## <center>How much space is there?</center> ##
<br>
The Universe may or may not be limitless. I cannot accurately define an answer to this question because the question itself is inaccurate. Is the limit of the Universe the limit of the most distance point of matter from us? Is it fourteen billion light years in one direction or fourteen billion in the other? It is known that the limit of the observable Universe is a with ninety-three billion light years of diameter. As the universe is only fourteen billion years old, and knowing that matter cannot travel faster than the speed of light, one can conclude that the material universe is actually something expanding inside a spacetime that is much larger than it, where a great majority of its volume is in fact devoid of matter. 

Thus, if there is a hard limit to the size of spacetime, what lies at its boundary? What lies on the other side? There must be -something- there, because if the universe existed relative to something else, that something else -must- also exist for our Universe to be relative to. A boundary always has two sides; the side it is bounding us into and the side it is bounding us away from.

## <center>Beyond our space</center> ##
<br>

If it holds true that we cannot travel beyond the limits of our dimension, we will never know what lies beyond the Universe, and I cannot even begin to imagine what may be out there. Is the limit something physically hard, like a shell that surrounds us all all sides, or could it be something more exotic, such as matter being something akin to a ray of light moving back of forth between two mirrors perpetually?

Such a concept is far beyond the comprehension of the human mind, as it breaks down the walls of the physical spacetime that we are bound to. It is simply impossible for us to imagine what the experience of a higher dimension is like, as we cannot visualize the relationship between dimensions from lower to higher. A cube becomes a tesseract, and we can imagine the tesseract in a three-dimensional space, but that is only an imagine of the tesseract projected onto 3D space, much like the drawing of a cube on a sheet of paper. It is in no way able to properly translate the cube from one dimension to the next. How do we imagine the tesseract in its natural space?
