Is there a cosmic wall 15 billion light years away? What is the nature of the universe wall that keeps us trapped?

More than half a century ago, through the rapid development of science and technology, human beings finally realized the dream of flying to the sky and walked out of the earth. Only when we really walk out of the earth can we feel the insignificance of the earth and see the vast universe.

The whole universe is endless. In the world with our naked eyes, the universe is dark, and we can’t see a few light spots flashing at all. But through astronomical telescope observation, we can see a brilliant bright universe through the dark.

The real universe is not dark, but the visible ability of our naked eye is limited, we can’t see those bright stars and galaxies. Under the astronomical telescope, the real face of the universe is revealed. The whole space is full of bright spots. They basically represent a large galaxy like the Milky way.

With the continuous improvement of human observation technology, we can see more and more areas. At the same time, we also understand that the universe is accelerating expansion. Due to the accelerated expansion of the universe, after the distance reaches a certain extent, the speed of photons there is less than the speed of space expansion, and light will never come to the earth, so there is an observable universe.

At present, the observable universe of mankind has a range of 93 billion light-years, which looks very wide, but this range may only be the tip of the iceberg of the whole universe. How big is the universe? No one can give an answer, but we have also found many strange phenomena in the observable universe. For example, an astronomical research team from Italy announced their new discovery, that is, the discovery of a “cosmic wall” 15 billion light-years away, and published the discovery in the form of a paper in the journal New scientist.

After the publication of the paper on the “cosmic wall”, it naturally attracted the attention of the scientific community and became a hot topic for discussion. According to the astronomical research team, the diameter of this “cosmic wall” has reached 3.5 billion light years, wrapping the space we live in. The temperature here is extremely low, and it may be close to absolute zero. We can’t see any matter, and it’s a silent dead place.

A cosmic wall with a diameter of 3.5 billion light-years trapped us in it? This result naturally makes many people feel incredible. So what is the essence of this so-called cosmic wall? Is it really the equivalent of a barrier that keeps us in it? Before we discuss the nature of the cosmic wall, let’s also look at a cosmic bubble theory.

This theory holds that there are different divisions in the universe, and the universe in a certain area is wrapped in a huge bubble. Even multi cosmology holds that different parallel universes are equivalent to a huge bubble. Are there any isolated areas in space? Is that possible? In fact, the possibility of its existence is relatively large.

Let’s take the small solar system in which human beings live. There is also a “bubble” around the outer solar system that envelops the whole inner galaxy. The famous scientist Tesla predicted the existence of this “bubble” as early as last century, but Tesla called it the energy mask.

So does this energy shield exist? The answer is yes. Scientists launched Voyager 1 and Voyager 2 in 1977. Their goal is to move beyond the solar system. Voyager 1, after decades of navigation, chose to reach the edge of the solar system. After arriving here, Voyager 1 observed the huge energy at the edge.

After Voyager 1 sent the data of the edge of the solar system back to earth, scientists naturally saw that there was a strong energy at the edge of the solar system. So how does this energy come from? According to the research of scientists, this is the energy produced by the collision of solar wind and interstellar space radiation. We all know that the solar wind is a kind of particle radiation, which radiates the entire solar system.

At the edge of the solar system, the radiation range of the solar wind has reached its limit. Beyond the solar wind that can not be reached, there is interstellar space, which also has very strong cosmic radiation energy. If this energy tries to enter the solar system, it will naturally have friction with the solar wind, thus generating a huge energy. This energy forms an “energy shield” to protect the solar system.

Since there are such “energy bubbles” at the edge of the solar system, it is not surprising that the whole universe is divided into different regions, and each region is also wrapped with a similar “energy bubble”. Of course, this is only a conjecture at present. Our observation ability is still very limited. Naturally, such bubbles cannot be observed.

So is the 3.5 billion light-year-old cosmic wall observed by the Italian astronomical team similar to the “energy bubble” at the edge of the solar system? In fact, this cosmic wall is essentially different from the energy bubble that envelops the solar system. They have different concepts.

We can use another word to replace the cosmic wall observed by astronomers, that is, the cosmic hole. We all know that the order of the universe is controlled by gravity, and gravity is the core power of the motion of matter in the universe. Stars, planets and other celestial bodies are formed by the condensation of matter through universal gravitation.

Countless kinds of celestial bodies converge to a certain region under the action of gravity, forming various galaxies. In a galaxy, the gravity is different in different positions. The closer to the center, the stronger the gravity, the more objects and matter will gather. And far away from the galaxy, the gravity is weak, so there are fewer celestial bodies and matter.

The same is true in cosmic space. The gravity will be different in different places. If the gravity is weak, a lot of matter will disappear. In the end, there will not be much matter in this area, forming an “open area”. There are so many “open areas” in cosmic space that scientists call them “holes”.

The diameter of holes in the universe is often very large. The larger holes can reach hundreds of millions of light-years or more. For example, in the supercluster Virgo, there is a hole with a diameter of more than 100 million light-years. And the cosmic wall that the Italian astronomical team measured in the appearance of 15 billion light years is actually a cosmic hole, but its diameter is larger, reaching 3.5 billion light years.

Of course, the hole does not mean that there is no matter in it, but there are very few celestial bodies and matter, which can not be observed by our current observation technology. So in the lens of the astronomical telescope, it looks like a huge area with nothing. Although the wall of the universe is empty, this result makes many people feel sorry, but the discovery of this huge hole is still of great significance for us to understand the universe.
