The exploration of the universe is endless. Throughout the ages, we have been full of curiosity about the extraterrestrial world. Through the combination of mathematics, physics, chemistry and other disciplines, we have unveiled the mysterious veil of the universe step by step, in order to get what we want. s answer. The scientist created a Mobius ring, which is an object that has no positive or negative sides. It is a ring, but it can be combined after reversal, regardless of how it can't distinguish between positive and negative sides. Isn't that the answer we haven't been able to find in space?

Next, we will introduce an object that we can't see in real life due to different dimensions. It is a Klein bottle. It has the same meaning as the Mobius ring. Since we can't create such an object, we can only draw such a four-dimensional object through a computer. This object is very strange, its bottle mouth can reach the bottom of the bottle through the four-dimensional space, and the freedom of entering and leaving is like there is no isolation zone, so the Klein bottle is a bottle filled with water.

The understanding of the Klein bottle can be extended to the universe. We live in the universe, and we can live in the universe. Because the boundaries are all at the mercy of others, that is, exploration is borderless. In the Klein bottle, the location does not affect the distance to go. Just as we are in the universe, exploration is endless, and every time we take a new step, there will be new surprises.

We are currently in three-dimensional space, four-dimensional space has not been well known by many people, but we can roughly understand the construction of four-dimensional space through computer drawing.
