In October 2018, the news that scientists had discovered the cosmic wall began to circulate online, and scientists discovered a vacuum band spanning 3.5 billion light-years in the constellation of Eridanus, about 15 billion light-years from Earth, which is the cosmic wall. So what exactly is a cosmic wall? That is, astronomers discovered a phenomenon when observing the universe, the universe space to a specific place there is nothing, what galaxies, stars, celestial bodies to there does not exist, but there is not a black hole, but a large cosmic range, as if there is a wall, the universe on this side of everything is isolated, drawing a boundary.
Of course, this wall is just a figurative metaphor, and such a concept has also attracted a lot of attention and various speculations, believing that this wall is the boundary of the universe, and some people speculate that it is the dividing line between different civilizations in the universe. Some people say that our universe is a prison locked up, and we people are trapped in it and can't get out. Others say that we were captive by a higher civilization. Earth is a testing ground, so this wall prevents us from escaping the universe.
In short, various theories have arisen around the cosmic wall. These various theories and reports are quoted from the reports of new scientists in international scientific and technological journals. However, after two years, scientists have made new discoveries, and the truth seems to be deliberately revealed to us step by step.
When looking up at the stars in Antarctica, no one knows what will be behind these stars, but in 2020, astronomers discovered a huge wall on the southern boundary of our universe, which is a spectacular and incredible wall, and contains thousands of galaxies. Located in the south of the solar system, the wall is more easily spotted in the Antarctic region, hence the name Antarctic Wall. Through observations, scientists preliminarily determined that the length of this wall is about 13. At 700 million light-years and more than 600 million light-years deep, it is one of the largest known structures in the universe. For a long time, Nanji Strong has been hidden from view until now, because most of its structure is located 500 million light-years away from the bright Milky Way, in other words, it is located in a place called the lead, which is obscured by bright stars, dark gas, dust in the galactic disk, so we can't see it. However, scientists chose to observe the redshift phenomenon of structures outside the galaxy, and eventually discovered the existence of the Antarctic Wall. Let's take a look at a computer model of the Antarctic Wall. Red shows the denser regions of matter, spanning about 1.3 billion light-years, and our Milky Way is at the center of this image, the birthplace of the red and blue arrows, only 100,000 light-years in diameter. Scientists have found that the Antarctic Wall is an arc of wood spanning at least 700 million light-years of space, winding behind dust, gas and stars in our galaxy, from the northern hemisphere of Cepheus to the far southern constellation of Swiftlet, and they have also found that its mass is so large that it disrupts the local expansion of the universe. The results were first published in the July 10, 2020 issue of the Journal of Astrophysics.
Daniel Pomaride, a cosmologist at the University of Saclay in France who participated in the mission, said the wall is bow-shaped, allowing its length to fit into the observed range. If it happens that the part of it that curves is beyond our observation limits, maybe we won't see all of it. To put it bluntly, humans are really lucky to be able to find its existence, and it feels like an arrangement in the underworld. Also because the South Pole Wall is about 1 billion light-years from the position of our solar system, this distance is not too far from the perspective of the universe, so scientists believe that the South Pole Wall plays an important role in studying the real structure of the universe.
Scientists have long noticed that galaxies are not randomly scattered throughout the universe, but are clustered together in a cosmic network. In this huge hydrogen chain, galaxies are like pearls on a necklace, surrounding a vast empty space of space. It has also long been believed that the structure of the universe resembles the cells of living things, especially nerve cells. Taking humans as an example, the human body has a neural network, all over the body, substances can be transmitted in neural networks, such as various neurotransmitters, and the brain controls the whole body through the neural network. The same is true of the universe, each supercluster is equivalent to a neuron in a neural network, which does not exist alone in the universe, but may have some special structural connections between neighboring superclusters. In this way, the entire universe seems to be spread over a network, called the cosmic network, and matter can be transmitted to each other through the cosmic network, so the cosmic network is also called the interstellar highway by scientists.
For humans, the solar system is already very huge. Our probes Voyager 1 and Voyager 2 have flown for more than 40 years and still haven't reached their outermost Oort Nebula. However, the solar system is only the smallest level of the cosmic system units. The cosmic hierarchy located above the solar system is the Milky Way. The Milky Way has more than 100 billion stars, including red supergiants 4.5 billion times larger than the Sun, called Uy Scuti, and red dwarfs with half the mass of the Sun. And galaxies also come in many shapes, we are in the mussel galaxy, in addition to spiral galaxies, elliptical galaxies and irregular galaxies. Our Milky Way and about 50 neighboring galaxies make up the Local Group. This is a smaller galaxy cluster, covering about 10 million light-years, and when the number of galaxies exceeds 100, it is called a galaxy cluster.
The closest galaxy cluster to us is the Handmaid Cluster, which contains more than 2500 galaxies. In fact, whether it is a galaxy group or a galaxy cluster, they are not the highest level in the cosmic system, and there is a greater existence above them, that is, superclusters. The supercluster we are in is called the Local Supercluster, because its center is the Handmaid Cluster, so it is also called the Handmaidservant Supercluster.
But even if it is the Handmaid's Supercluster, it is not the largest size structure, it belongs to a structure called Raniakea, which is also the largest supercluster discovered by humans, and the South Pole is stronger than the Raniakea Supercluster, and the range of Raniakea is only 5. 200 million light-years, but the Antarctic Wall extends twice as far. So in terms of location, the South Pole Wall is behind the Raniakea Supercluster, about 500 million light-years away, so the South Pole Wall can also be understood as our huge neighbor. So far, the largest system in the universe is the superstar group, and scientists do not deny that there are larger systems above the supercluster, but it has not been discovered by current astronomical observations. The South Pole Wall is likely to be another cosmic structure outside the supercluster, which connects the existence of different superstar groups, and they are connected in the form of a filament, which may be woven from dark matter.
Having said that, although Antarctic Qiang stretches for a distance of about 1.4 billion light years, it is still too small compared to another similar structure, that is, the largest structure in the universe currently observed by humans, the Great Wall of Northern Burma. The Great Wall of galaxies stretches for more than 10 billion kilometers, about 10 times the size of the Antarctic Wall. As a result, scientists proposed the structure of the universe with fibrous structures, and they believe that whether it is a supercluster or the Great Wall of the Five Immortals of Northern Myanmar, such a galaxy Great Wall is a fibrous structure. Perhaps there is still a giant fibrous structure in the universe that is larger than the Great Wall of the Five Immortals North Burma. Having said all that, we still feel like a blind man touching an elephant, what do we see? Judging from what you see, so it is often the more you dig yourself, the more chaotic it is, in the final analysis, what is the universe strong? Is our planet really a prison in prison? According to the Buddhist scriptures, our galaxy is known as the world of Baba, and it was concluded that there are 1 billion stars in the Milky Way long before modern astronomers.
The Buddhist scriptures say that the world of Baba is made up of 1 billion small worlds, each containing a sun and a moon. It is also believed that the world is composed of three thousand worlds, that is, the world is composed of 1000 large worlds, and each large world is composed of 1000 middle worlds, and each middle world is composed of 1000 small worlds, which is equivalent to a solar system. That is to say, there are a total of 1 billion small worlds in the three thousand worlds. Buddhism's understanding of the small world is different from what we call the solar system. We generally believe that the planets revolve around the sun, and the sun is the absolute center of the solar system. However, in the Buddhist cosmology, the center of the small world is not the sun, but Mount Void, and both the sun and the moon rotate halfway up Mount Void. According to the Buddhist scriptures, Mount Meru is the most famous sacred mountain in the Three Realms, also known as Mount Meru. The sacred mountain is extremely tall, in the center of our three realms, you can't see its side when you look at both sides, you can only see halfway up the mountain, and you can't see the edge when you go straight into the sky.
When we read classical novels, we often encounter such a sentence, jumping out of the three realms, such as Journey to the West and Romance of the Gods have similar expressions. The three realms are the Buddhist concept, the so-called three realms, that is, the desire realm, the color scale, and the colorless level. Buddhism believes that each of the three realms contains several heavens, and the three realms total 28 days. Buddhism has another concept, the thirty-three heavens, but unlike the 28 days, it is another name for the second day of the desire world. Later, the thirty-three layers of heaven were more widely circulated, while the 28 days in the three realms were less known. But regardless of whether there are 33 heavens or 28 days in the three realms, the Buddhist scriptures say that Mount Meru is at the center of the three realms. Mount Meru is surrounded by eight mountains, which, together with Mount Meru itself, are collectively known as the Nine Mountains and the Eight Seas. The sea on the inner side is fresh water, and near the outermost iron mountain, it is salt water, the sun, moon, stars, and even the color scale of the Zen sky, and even the wind wheel under the earth. Such a world is called a small world.
In other words, a small world contains people, hell, demons, beasts, asuras, and the heavenly realm of the heavenly path, the color scale of the Zen heaven and the sun, moon and stars, which is equivalent to a solar system world, and the lowest layer of each small world is a layer of qi, called the wind wheel, and above the wind wheel is a layer of water, called the water wheel. Above the water wheel is a layer of gold, called the golden wheel, and above the golden wheel is the earth composed of mountains, ocean continents, etc., and Mount Meru is located in the very center of this world.
Not only that, Mount Meru is surrounded by four continents, namely East Katsu Shinshu, West Uiga Prefecture, Nanzhan Bu Zhou, and Luzhou in the north. Then our earth is located in the southern island of Mount Meru. For life in the three realms, including the celestial beings, Mount Kamiyama is an boundless existence, and from the scope of this cosmic space, this Mount Meru is much larger than the entire solar system.
So if what the Buddhist scriptures say is true, such a big mountain, why can't people see where it really is? Could it be that space-time folds or multidimensional space isolates us from each other? Or is there some special cosmic barrier? Or is it that our human eyes cannot see its real existence? After all, the human naked eye is indeed very limited, this part we also talked about in the video of the eye of the sky, will there be another possibility, that is, astronomers found these so-called galactic walls or cosmic walls, will it be accidentally discovered part of Mount Meru? After all, Mount Meru is so big, and there are so many mountains around it, right? So it seems that the statement that our earth is a prison does not seem to be true, but from another point of view, we people are indeed trapped in the three realms, at least the religious community says so, and modern astronomers have gradually discovered this.
In 1986, astronomers announced that in a large expanse of sky in the direction of Centauri, galaxies were flying much faster than Hubble's law predicted, as if they were being pulled toward something. Astronomers call it the big attractor, and they believe that this giant attractor is likely the central region of the Ranikian supercluster, which humans inhabit. All the different parts of this superstar group are pulling us, so where is he pulling us. This may reveal another cosmic mystery in the future.
This corresponds to the discovery by astronomers in 1965, when they discovered that space was filled with microwave radiation left over from the birth of the universe 13.5 billion years ago. Subsequent observations showed that the radiation was not uniform, but slightly warmer in one direction, suggesting that our Earth's galaxy and local galaxy are moving toward Centaurus at about 400 miles per second like goldfish in a fish tank, with the final destination being a more distant place. So the question is, why is this? So what is on the other side of this so-called fish tank that is attracting us closer step by step? Astronomers say the main reason for this movement is the large attractor, and of course there is also the influence of the Antarctic Wall, but this is only part of it, and most of it is something that we cannot see directly. So if it's true that we're really stuck in a fish tank, as astronomers have described, or as religious circles say, we're trapped in the three realms. So who is using this attractor to manipulate the motion of our galaxy? And where that final destination is, I'm afraid we'll never know. The universe is so mysterious, human beings are so small, I think we still have to face everything in the world with a little awe.
