We all know that the vast cosmic space contains one layer. The world outside the earth is the solar system. The starry sky outside the solar system is called the Milky Way, and the outside of the Milky Way is a larger super galaxy cluster. There is also more vast space outside.
This interlocking cosmic structure forms the cosmic space network we see now. The observable universe of mankind currently reaches 93 billion light-years. From the perspective of the universe, the Milky Way is only the smallest observation unit. The structure of star clusters with a diameter of hundreds of millions of light-years or even billions of light-years constitutes the vast universe. The main unit.
In the observable universe, scientists believe that under the influence of gravity, visible matter forms a huge “three-dimensional network”, which is a giant cosmic fibrous structure with a range of 93 billion light years. Within this vast range, each node that makes up the network is a cluster of galaxies.
So does this vast fibrous structure show a uniform and dense distribution? The answer is no. Through a large number of observations and studies by scientists, it has been found that the distribution of matter in the universe is uneven. From the perspective of the earth, the solar system has eight planets and a large number of asteroids. This is a galaxy with densely distributed matter.
But from the perspective of the Milky Way, the solar system is at the edge of the Milky Way, 26,000 light-years away from the center. It is a star with sparsely distributed matter. In the Milky Way, celestial bodies and densely distributed areas are mainly concentrated near the center of the Milky Way.
So standing in a larger supercluster outside the Milky Way, is the area where the Milky Way is located in an area with denser celestial bodies? In fact, the location of the Milky Way in the supercluster is relatively close to the edge, not in the central area. So from the perspective of the fiber-like structure of the entire universe, what is the position of the solar system? Is it an area with rich celestial matter or an area with very little celestial matter?
According to the continuous observations of scientists, the solar system may be in a huge “cosmic cavity” with a diameter of 2 billion light-years. Many of my friends may not understand the void of the universe. It is actually an astronomical term, which generally refers to the space between the fiber-like structures of the universe. As we said earlier, the entire observable universe is equivalent to a fibrous three-dimensional structure. In this structure, there are countless nodes connected to each other to form a cosmic network.
And there are spaces between nodes and nodes, some are relatively small, some are particularly huge, and those huge spaces are called cosmic voids. It can be called a cavity, which means that the material distribution here is very scarce, and the entire cavity contains only a few galaxies or no galaxies at all.
A cosmic cavity is a very special and terrifying region in the universe. Scientists have yet to understand how the vast cosmic cavity is formed. It is very normal for matter to be unevenly distributed in the universe. This is because different places receive different gravitational forces. The matter distribution in areas with high gravity is naturally denser, and areas with low gravity are very sparsely distributed.
If you still don’t understand the void of the universe, we can use a fishing net as an analogy. We all know that if a fishing net is used for a long time or is damaged, some large holes will appear in the originally densely distributed net. The same is true of cosmic holes. It is also in the vast network of the universe. For some reasons, some particularly huge holes have appeared. They are cosmic holes.
In the horizon of the astronomical telescope, the cosmic cavity is completely dark, and no galaxies and material reflections can be seen. The temperature there is also extremely low, much lower than the temperature of the surrounding starry sky. Just like this, cosmic black holes are not a difficult-to-discover area. What’s more important is that cosmic holes are often very large, small ones are millions of light-years away, while larger ones can reach hundreds of millions of light-years.
American astronomers have discovered that there is a super “hole” with a diameter of about 1 billion light-years in the universe. There are no stars, no galaxies, and no mysterious invisible dark matter. Of course, nothing does not exist in the void of the universe, but the matter there is very scarce, and galaxies and celestial bodies are also extremely rare.
Human observation technology is also very limited, so it is difficult to observe the situation in the cosmic cavity, only to see huge black holes distributed on the background map of the universe. Why do scientists say that the solar system may be in a huge hole? In fact, it was mainly discovered by observing the solar system and the surroundings of the Milky Way.
As we know, the solar system is about 4.2 light-years away from the nearest neighboring galaxy. In this area, there is almost no matter in sight except for some interstellar medium. Of course, from the perspective of the Milky Way, there are still many galaxies and matter near the solar system.
However, when we stand from the perspective of the Rania Kea supercluster, we will find that the Milky Way is not in the center, and it is a region with relatively sparse material distribution. Not only that, it is a super-large structure such as the Rania Kea supercluster of galaxies. Its location in the universe is not in a densely distributed area. On the contrary, its location is likely to be located in a super-large hollow structure. The diameter of this hole Reached 2 billion light years.
Of course, these are only our current preliminary observational structure. If we want to get more accurate information, we cannot do it with the current scientific and technological strength of mankind. After all, human beings are in this void, and it is normal to be in it without knowing the true face of Mount Lu.
We want to really understand whether the solar system exists in a huge hole, then the most intuitive way is to go out and observe the solar system from a more distant starry sky, so that you can see what kind of space the solar system is in the universe. Inside. To get out of the range of 2 billion light-years, we need to truly master the mysteries of time and space, and have the technical strength to break through and shuttle through space.
Perhaps only the wormholes that have been explored and studied can go out and let us truly understand where the solar system is. If the entire galaxy cluster in which the solar system is located is really in a huge cosmic hole, then humans cannot find alien civilizations, and perhaps there is a new explanation.
In a cosmic hole, the distribution of galaxy matter is small, then the probability of birth of a planet of life will be very low, and it is not easy to be able to appear as a planet of life in the hole where we are. . Therefore, in this cavity with a diameter of 2 billion light-years, perhaps there is only one civilization of humans.
The cosmic void may be a natural cosmic barrier, making it difficult for other intelligent civilizations to enter and detect it, so alien civilizations do not know the existence of the earth and human beings. If so, it is good news and bad news for the earth and mankind.
The good news is that our future development is very safe. We don’t need to worry about the threat of alien civilization. The downside is that we may not be able to contact alien civilization for a long period of time in the future. Only after possessing the superluminal technology that spans the interstellar, can we hope to get out of this void.
