The universe is a complete space-time structure, with all spatial structures and all temporal structures. Very grand, the Milky Way is very huge, it is not a dust in the universe. Very mysterious, full of countless different time and space, each time and space has its own different time field, time period, space size, space shape, and all kinds of laws that suit it. Parallel spacetime is interrelated. For example, the nine planets and nine spacetimes in the solar system all have their own orbits, which are arranged in order, corresponding to the Taiji structure of the human body, and the arrangement order is the same. In ancient China, people used holographic multidimensional thinking to know that everything in the universe has holographic multidimensional space-time, so it is easy to find their holographic correspondence. The same is true of vertical space-time. For example, the earth is Saturn, but the center is nearly 6000 degrees of molten iron; The solar system is such a big earthen dish surrounded by nine planets. The sun is at the center, and the surface is 6000 degrees of molten iron, which all have holographic correspondence with the Tai Chi structure of the human body, another Tai Chi, another arrangement order and different Tai Chi numbers. Space-time in the universe has infinite subspaces corresponding to this kind of transverse and longitudinal holography, and they also correspond to the Taiji structure of human body. Because the universe is a giant. Everything in the universe is made up of small particles and evolved, just like seeds and leaves evolved into trees. The universe evolved from the human body and experienced numerous qualitative changes. The same is true of the human body that evolved from fertilized eggs. The truth of the universe is infinite, which urges people to set up great aspirations for goodness.
