The world before us is in constant motion, folding and unfolding. If we are sensitive enough, and have open minds, we can have a glimpse of the fascination of the creation during each folding and unfolding. Knowledge comes to us. Everything in the universe is there, past, present, and future. All we need to do is to tune in.
Now, back to the hypercube. Let's start from a 3D cube. A 3D cube unfolds into 6 squares on 2D plane. Take one square, and 4 squares around it, plus one more tagging along the end of any direction, we can fold these 6 squares into a cube.
Similarly, a 4D hypercube unfolds into 8 3D cubes. Take one 3D cube, and 6 cubes around it (in all 3 directions), plus one more tagging along the end of any direction, we can fold these 8 cubes into a tesseract (4D hypercube).
A 5D hypercube unfolds into 10 4D hypercubes. Take one 4D hypercube, and 8 4D hypercubes around it (in all 4 directions), plus one more tagging along the end of any direction, we can fold these 10 4D hypercubes into a penteract (5D hypercube).
Higher the dimension, the more "compact" is the hypercube, the more information does it contain.
When we can tap into the higher dimension, we receive knowledge that we don't get normally. And when we are present in higher dimension, we see more at once.
When the dimensionality goes to infinity, the hypercube becomes so "dense" that it turns into a point. At that point, one sees everything, past, present, and future. There is no time. And it is God.
