[New Tang Dynasty Beijing August 07, 2021]Where is the edge of the universe? Perhaps many people have thought about this problem more than once. At present, with the short-term technological level of human beings, our observable universe is 93 billion light-years in diameter, but unfortunately, since the universe is currently expanding at a speed faster than light, our technological development is far inferior to the expansion of others. Speed, so there is no way to know what is the side of the universe today.
In the previous article, we introduced that the solar system is on a branch spiral arm of the Milky Way, and there are not many stars distributed around us, which also guarantees the safety of the earth. But what we need to clarify is that even if there are 400 billion stars in the Milky Way galaxy, below its 100,000 light-year diameter scale, the average star density is still very low on the plane of the silver disk, that is to say. In the Milky Way, most of the space is very “empty”.
The Andromeda Galaxy is the galaxy next to the Milky Way, our neighbor, and the closest galaxy to us. It is 2.5 million light-years away, and it is twice the size of the Milky Way. Therefore, the Milky Way, the Andromeda and the surrounding small galaxies form a group of galaxies, which is called the “local group of galaxies.” Researchers predict that the Andromeda is currently moving toward us at a speed of 120 kilometers per second, so in the next 4 billion years, two galaxies may form a new galaxy.
The diameter of the local group of galaxies has reached 10 million light-years. Within the range of 110 million light-years including the local group of galaxies, it and more than 100 other groups of galaxies form the Virgo supergroup. Looking bigger, the Virgo Supercluster is once again part of the Rania Kea Supercluster. The diameter of the Rania Kea super galaxy cluster has reached 520 million light-years, and it mainly includes the Virgo Cluster, the Hydra Cluster, the Centauri Cluster, Abel 3565, Abel 3574, Abel 3521, and the Furnace Galaxy. It is composed of 300 to 500 galaxy clusters and groups of galaxies, such as the constellation of galaxies in the constellation of Galaxies.
Similarly, under such a giant scale, the density of galaxies is still very low. Under such a scale, the planet is like a particle of dust in our living space, appearing particularly emptiness and misty. However, in such a seemingly empty space, researchers discovered that the largest known structure of the universe is a large-scale fibrous structure, which is like a huge net, and these fibers connect all the empty world in Together. This is what this net looks like:
Have you discovered whether this huge network of the universe resembles the capillaries in the human body, or more accurately the veins of the human body. There are no blood vessels in the center of the heart of the human body, and only the veins are left. , The various muscles are tightly connected together. At the same time, we can also compare this large network with the context in the human brain, which is also extremely similar-this is a large-scale “brain” network.
Buddhism says: “Heaven and earth are a big universe, and the human body is a small universe.” The universe itself is even a part of the body of higher-level beings on a larger scale. Now this sentence is really well confirmed in science.
