And again, it is just a concept, it's not visible to the human eye (because our perceptions only work with three dimensions). Given that, it is only understandable thanks to mathematical and ideational tools. The zero-dimensional space (0D) is the nothingness, just a point , a position, a dot. The one-dimensional space (1D) is a line , the length. The two-dimensional space (2D) is a plane , the width. The three-dimensional space (3D) is a  solid , the depth. And the four-dimensional space (4D) is time , the consolidation of time-space.  Although the strings theory says that there are ten dimensions in total, I won't focus on those other six during this post, just in the fourth o...
