The "wall of the universe" was found to span 3.5 billion light years. How did it come into being? Is human really "imprisoned"?

The well-known scientific magazine "New Scientist" once wrote that a special structure with a span of 3.5 billion light years was found in the constellation Bojiang, which is 0/500 million light years away from the earth, and it was called the "cosmic wall".

Such reports in the media have caused a deep misunderstanding among the general public, thinking that the edge of the universe has really been discovered, or that it is a cage that imprisons human beings.

If higher life factors are added to the "cosmic wall", then human beings will once again become the object of alien experiments. I don't agree with this statement, and I hate this irresponsible marketing number. Every article they read is like not reading it, and people who read it are puzzled.

First of all, let's not talk about what this "cosmic wall" is. Let's start with New Scientist. This scientific magazine was founded in Italy on 1956. Its essence is a news periodical, including some review articles.

It is not rigorous, similar to nature and science? Professional scientific journals such as Cell. Therefore, the report published in New Scientist does not need rigorous scientific review and peer review, but is more a press release with strong personal views.

The word "cosmic wall" is a typical example. It's not a scientific statement, it's an image metaphor of the author. What you know is naturally understood, and what you don't know is misled. The media will also seize this stunt and vigorously promote it.

So what is the "cosmic wall"

"The universe is powerful" means that the universe is super empty in professional terms. We know that in addition to planets, stars, clusters, galaxies and other structures, there are larger clusters of galaxies (clusters) and superclusters composed of galaxies.

In our impression, the universe should be full of these material structures, which are evenly distributed on a large scale, but the real situation is that material structures really only occupy a small part of space, and many interstellar spaces are really empty.

Then these regions with no material structure, except the planets and stars mentioned above, have no dust, gas or even invisible dark matter, so such regions are called cosmic supercavitations.

The universe is super empty. In our view, there is no light, it is a completely dark area, in sharp contrast to the area with galaxies around it.

In particular, the hole found in the constellation Bojiang, which spans 3.5 billion light years, hangs in front of our vision like a black curtain. Does it look like a wall?

To tell the truth, the metaphor of "cosmic wall" is really good and vivid, but when we compare it, we need to explain to readers what its essence is, instead of deliberately creating misunderstandings.

So what does this "cosmic wall" look like on a large scale?

Thanks to the development of various telescopes, we can now study the universe on a large scale, as long as we observe how the material structure is distributed in the universe on a scale of billions of light years.

Through investigation, we found that the galaxies and clusters of galaxies in the universe have formed the filamentous structure shown in the above picture on a large scale, in which the luminous areas are all areas with high material density, that is, full of galaxies, so the dark area is a hole.

On a large scale, it has nothing to do with the fence. However, one interesting thing about the large-scale universe is that it looks very similar to the neural network in our human body, so the majority of netizens speculate whether the universe will be a creature.

The idea that we just live in one creature is artistic, but it can't be true. It can only be said that our macro universe and micro world have the same nature in some aspects and abide by the same physical principles, so this similarity will occur.

Carl sagan once said: The atom in the universe, the universe in the atom. This means that there is a certain * * * between macro and micro. It is a bit bizarre and arbitrary to say that the universe is a cell, or that we live in creatures.

In addition to observing the universe on a large scale, we also have microwave background radiation, which not only contains a lot of information of the early universe, but also shows the material distribution of the early universe.

Blue dots and red dots represent cold spots and hot spots, that is, low temperature zone (high material density) and high temperature zone (high material density), but the fluctuation of this temperature is very small and only occurs on the micro-Kelvin scale.

This shows that the distribution of matter in the universe is relatively uniform, which causes why we see the same thing no matter which direction we look at, and also creates the illusion that the earth is the center of the universe.

So who built these "cosmic walls"?

We know that when the cosmic microwave background radiation was emitted, the age of the universe was about 380,000 years. At this time, neutral atoms have been formed, mainly composed of hydrogen, helium and a very small amount of lithium.

At this time, these gas clouds fill the space, but as mentioned above, there is a slight density difference in the distribution of matter in the universe. At this time, under the action of gravity, substances will begin to gather in high-density areas, attracting more and more species.

This has caused those areas with low material density to be deprived of a lot of material and unable to form an effective material structure, thus forming a cavity.

There will be more and more substances in high-density areas, which will gradually condense until nuclear fusion is ignited to form stars, galaxies and even later clusters of galaxies.

Therefore, the "person" who makes the material structure is gravity, and the "person" who makes the giant hole is also gravity. However, in addition to gravity, there is also the help of dark energy. At present, the expansion of the universe is accelerating, and those substances that are not bound by gravity will be farther and farther away.

Therefore, the supercavitation of the universe will gradually increase and increase in the future.

Are we imprisoned by the so-called higher life?

This statement is more about awe of the universe, and then fantasy. When we look up, we can see the stars. Photons travel through tens of billions of years of space and transmit the ancient information of the universe to the earth. The universe has always been an open state for us.

When human beings can't overcome gravity, they feel imprisoned on the earth. There are so many stars in the sky that we can only look at them and can't reach them at all.

When humans have the ability to ascend to heaven one day, they will also set foot on the moon, the brightest celestial body in the night sky.

At present, our farthest aircraft has also flown away from the top of the solar wind. One day it will also fly out of the control range of the sun's gravity. As long as our technology is advanced enough, it is not impossible for us to leave the galaxy in the future. Everything depends on the level of human scientific and technological development.

If there are really higher creatures imprisoning us, do you think they will make us live so comfortably on earth? Will it let us mess around in the solar system?

There is no denying that in such a huge space, it is impossible to have only human beings as the only intelligent life. It is very likely that they are much more developed than our science and technology, which is the knowledge of the scientific community.

But so far, such life has not been discovered by us, and they have not visited the earth. Whether it is the explanation of the dark forest, the big filter of life or other insurmountable factors, it is only human speculation at present.

We can't explain exactly why humans haven't seen aliens yet. I think all kinds of speculations about aliens can only be answered when they really meet one day.
