There is no doubt that we are now in three dimensions. If we stare at a flat piece of paper, we see it as two dimensions. I folded this two-dimensional paper, and it can be presented with the three-dimensional length, width, and height. Then flatten it again, draw the folded piece of paper we just saw on this flattened one, and the three-dimensional is presented in the way of two-dimensional. At this time, the three-dimensional paper exists in four-dimensional space (we are always surrounded and incorporated by high dimensions), and the two-dimensional paper appears on three dimensions. Then, I cut off the center part of the two-dimensional paper I drew. Now, what is the relationship between this two-dimensional appearance and four-dimensional? For our vision, it is an inclusive relationship, but is that true?
