How to locate the coordinates of the earth in the universe with gossip?

Our present universe uses three-dimensional coordinates to represent space, and eight hexagrams are flat. Many galaxies in the universe move on the same plane. For objects in plane motion, gossip can explain. At present, people find that it is not enough to describe the universe only with three-dimensional space theory. We need the help of eight diagrams, but eight diagrams can't completely describe the universe. We are still looking for tools to understand the universe. Children's shoes, come on, the task of saving the universe falls on you.
