How to understand the multidimensional universe, and how to understand multidimensional? Can you make it easy to understand?

Suppose the line is a one-dimensional creature living in its own one-dimensional world, and can only see zero-dimensional things, that is, a point. Even if its world intersects with the two-dimensional world, that is, the plane, the intersection point can only be a line, which is the projection of the two-dimensional world in the one-dimensional world. So he can never imagine a two-dimensional world. But for himself, every time he looks at a point, he can imagine, oh, I am like this.

Similarly, a two-dimensional creature, a face, can only see one dimension The projection of the three-dimensional world in the two-dimensional world is a surface.

A three-dimensional creature, that is, we can see a two-dimensional plane, and through imagination and synthesis, we can get the whole picture of us. No one can see three-dimensional objects.

In this way, the four-dimensional universe and four-dimensional creatures can see the three-dimensional panorama at a glance. The four-dimensional self, which we can't imagine, is like a straight line that can never see a face clearly.

But the projection of the four-dimensional universe in our three-dimensional universe will be three-dimensional. We add a timeline to this three-dimensional problem, so the four-dimensional universe is the sum of a three-dimensional body on the entire timeline.

This is a world that we can treat rationally, but we can never see through. And so on.

What would a higher dimension look like? I really want to know.

I don't know what you think of this description.
