The universe that we can see or react to is called the visible universe, or more strictly baryonic matter. It’s only about five percent of the universe. The branch of science that deals with its structure is called particle physics. In the early days, the earth was the center of the universe.
Although we have come a long way since then, much of the universe is still in its infancy. The invisible matter that determines the unity, motion, and shape of the galaxy is called dark matter. It is thought to make up 27% of the universe. Let’s say.
Everybody is waiting in the lab ??? -?????? filled with liquefaction at a depth of 5000 feet to catch them. Those 5% of the visible and visible universe are galaxies that look like twinkles in the dark matter infinity in the image below. Another large 27%, a large cane, covers us and hides.
