However, with the continuous progress of human civilization, some of these wise men have learned through long-term observations and thoughts that the sun, moon, and stars in the sky do not belong to the earth at all, but are celestial bodies outside the earth. After continuous development, hundreds of years ago, mankind entered the road of scientific development and developed astronomical telescopes.
With the astronomical telescope, we can see farther and see the true colors of some celestial bodies outside the earth. At this time, we finally understand that there is a wider world outside the earth. So scientists began to study and explore how to get out of the earth, and this dream of flying to the sky was soon realized by us.
When we walked out of the earth, we really saw the vast universe. In front of the universe, the earth is as small as a grain of dust. Of course, for human beings who have just stepped out of the earth, we only saw a vast solar system. Later, with the continuous improvement of observation technology, we saw the Milky Way outside the solar system.
The solar system is just a dust in front of the Milky Way. There are 100-400 billion stars in the entire Milky Way, and every star basically has a star system. So is the Milky Way big? From the perspective of the solar system, its diameter is 100,000 light-years, which is indeed very large. But when we had more advanced observation technology, we also traveled through the Milky Way, and saw the vastness of the starry sky outside the system.
So what kind of galaxy structure is outside the Milky Way? In the past, scientists observed that the Milky Way belongs to the Virgo super galaxy, which is a galaxy with a diameter of 110 million light-years and includes 47,000 galaxies. So is this cluster of galaxies the largest cosmic structure outside the Milky Way?
After more advanced observations, scientists have discovered a more vast superstructure of the universe outside the Milky Way, with a range of 520 million light-years. This newly discovered super cosmic structure is the Rania Kea supercluster, and the Virgo supercluster as we know it is only a part of the Rania Kea.
The Rania Kea supercluster contains about 100,000 galaxies with a range of 520 million light-years, and the mass is 100,000 times that of the Milky Way. Our Milky Way is located on a “tassel” on the network of the superstructure of the universe. If this super structure is reduced, it is a large-scale fibrous shape, like a huge net.
These fibers form the boundary of the void in the universe. There is almost nothing in the void of the universe. “Fibers” are composed of super galaxy clusters. The places where these filamentary fibers intersect back and forth are huge clusters of galaxies, and the blank part of the filaments is the void of the universe.
The so-called cosmic void refers to the blank area of the universe, where there is almost nothing. In the lens of an astronomical telescope, there is a dark area, which looks like a huge black hole. Of course, the cosmic hole is not completely free of stars and other celestial bodies, but the number is too small and the light emitted is too dim for us to observe.
It can be seen that the structures of galaxies and star clusters in the universe are not evenly distributed, but are arranged unevenly. This uneven structural arrangement forms a huge cosmic network consisting of various criss-cross lines. The locations of these lines are where the star clusters gather.
Scientists observe and analyze the trajectories of galaxies, and after mastering a large amount of data on the distribution of galaxies, we can draw a cosmic starry sky network. This network is very important for mankind’s future exploration of the universe. We all know that we need satellite navigation for our travel on the earth. Without the existence of the earth’s network, it is easy for us to get lost and find our way home.
This is true for a small earth, let alone the vast expanse of the universe. When mankind will become an interstellar civilization in the future and move towards the universe, if there is no picture like the cosmic network, we will easily get lost in the universe and never find a way home.
You must know that the environment of the universe is harsh and cruel. Once you lose your way on the interstellar path, you may face death. Therefore, our future interstellar road needs a huge and complete network map of the universe, which is our navigation map to the interstellar. With it, you can go to the universe freely, otherwise there will be no return.
Of course, this kind of thing is still very far away from us. Many people will have this question: With such a huge and vast universe super structure, is there any hope for mankind to go out? Perhaps in the eyes of many people, the theory of relativity tells us that the fastest speed of an object is the speed of light, and even if humans achieve the speed of light, it would take at least 520 million light-years for us to fly out of the Rania Kea supercluster.
If calculated at the speed of the fastest human aircraft, it would take at least 4.4 trillion years. You know, the universe was born only 13.8 billion years ago, and at the current speed of the aircraft, it would take 4.4 trillion for humans to pass through the Rania Kea super galaxy cluster. This obviously tells us that human beings will never get out of this superstructure of the universe.
Even if we achieve the speed of light, it is impossible to go out. Does this structure make many people feel desperate? We must know that this super structure of the universe is only the tip of the iceberg of the vast universe. There are still many superstructures such as the Rania Kea supercluster in the universe. At present, we have discovered multiple galaxy clusters such as the Hercules supercluster and the Perseus-Pisces supercluster. Each of them can be comparable. Rania Kea Super Cluster of Galaxies.
If we can’t even go out of a small Rania Kea supercluster, what else can we talk about exploring the mysteries of the entire universe? In fact, we don’t need to be pessimistic at all. The speed of light is not the fastest in the universe. The fastest speed of an object in the theory of relativity is the speed of light, but the theoretical speed in a stable three-dimensional space has limitations.
General relativity tells us that the universe is distorted, and the existence of space distortion makes the speed not limited by the speed of light, and there is no upper limit. The expansion of the universe is obviously far beyond the speed of light, otherwise it would only expand to a range of 13.8 billion light-years in 13.8 billion years.
But in fact, the current observable range of human beings has reached 93 billion light-years, and beyond the observable range, there is even more vast space. It can be seen that the expansion speed of the universe far exceeds the speed of light, and this super-light phenomenon is the result of space distortion. As long as we can master the mysteries of space and have the ability to warp space, then we can achieve space jumps or wormhole shuttles.
At that time, human spacecraft can easily traverse various galaxies, traverse various star clusters, and reach every corner of the universe. Of course, this super-light-speed navigation mode is still a conceptual theory under conjecture for current human technology, and we are still far from realizing it.
For humans, there is no shortcut to science. We only have one step at a time. We will first study how to achieve sub-light speed, explore the entire solar system, and then go out of the solar system to explore the entire Milky Way. After our scientific and technological strength has reached a certain level, we will naturally be able to master the super-light technology and the space jump technology. At that time, human beings are truly powerful.
