More than half a century ago, through the rapid development of science and technology, mankind finally realized the dream of flying out of the earth. Only when we truly get out of the earth can we feel the smallness of the earth and see the vast universe at the same time.
The entire universe is endless. In the world of our naked eyes, the universe is dark, and there are no light spots flickering at all. But through observing through the astronomical telescope, we can see a wonderful colorful and bright universe through the darkness.
The real universe is not dark, but our naked eyes have limited visibility and cannot see bright stars and galaxies. Under the astronomical telescope, the true appearance of the universe is revealed. The entire universe is full of bright spots, and they basically represent a large galaxy like the Milky Way.
With the continuous improvement of human observation technology, the area we can see is getting larger and larger, and we also understand that the universe is accelerating. Due to the accelerated expansion of the universe, after the distance reaches a certain level, the speed of photons there is less than the expansion speed of space, and light will never reach the earth, so there is an observable universe.
The current observable universe of mankind is 93 billion light-years away, which looks very wide, but this range may be only the tip of the iceberg of the entire universe. How big is the universe? No one can give the answer, and we have observed many strange cosmic phenomena in the observable universe. For example, an astronomical research team from Italy announced their new discovery, which was in 150 A “cosmic wall” was discovered 100 million light years away, and the discovery was published in the journal “New Scientist” in the form of a paper.
After the publication of the paper on the “cosmic wall”, it naturally attracted the attention of the scientific community and became a hot topic of discussion for a time. According to the astronomical research team, this “cosmic wall” has a diameter of 3.5 billion light-years and envelops the cosmic space we live in. The temperature here is extremely low and may be close to absolute zero. We can’t see any matter. Existence is a silent place of death.
A cosmic wall with a diameter of 3.5 billion light-years traps 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 equivalent to a barrier trapping us in it? Before discussing the nature of the cosmic wall, we also come to understand a cosmic bubble theory.
This theory believes that there are different divisions of cosmic space, and that the cosmic space within a certain area is wrapped in a huge bubble. Even multiverse theory believes that different parallel universes are equivalent to a huge bubble. Are there various isolated regions in the universe? Is this possible? In fact, the possibility of its existence is still relatively large.
Let’s take the small solar system where humans live. There is also a “bubble” on the periphery of the solar system that envelops the entire inner galaxy. The famous scientist Tesla predicted the existence of this “bubble” as early as the last century, but Tesla called it an energy shield.
So does this energy shield exist? The answer is yes. Scientists successively launched Voyager 1 and Voyager 2 in 1977, and their goal is to advance outside the solar system. After decades of voyage, Voyager 1 chose to reach the edge of the solar system. After arriving here, Voyager 1 observed the huge energy of the edge.
After Voyager 1 sent the data on the edge of the solar system back to the earth, scientists naturally also saw a powerful energy at the edge of the solar system. So how does this energy come from? Scientists believe that this is a burst of energy generated 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, and beyond the inaccessible solar wind, there is interstellar space, which also has very powerful cosmic radiation energy. This energy will naturally cause friction with the solar wind when it tries to enter the solar system. This produces a huge amount of energy. This energy forms an “energy shield” that wraps and protects the solar system.
Since there are such “energy bubbles” at the edge of the solar system, it is not surprising that the entire universe is divided into different regions, and each region also has a similar “energy bubble” package. Of course, this is just a guess at present, our observation ability is still very limited, and it is naturally impossible to observe such bubbles.
So is the 3.5 billion light-year-in-diameter cosmic wall observed by the Italian astronomy 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, and they are different concepts.
The cosmic wall observed by astronomers can be replaced by another word, which is the cosmic void. We all know that the order of the universe is controlled by gravity, and universal gravity is the core power of the movement of the universe. Stars, planets and other celestial bodies are formed by condensing matter together through gravitation.
Countless various celestial bodies converge in a certain area under the action of universal gravitation, forming various galaxies. Within a galaxy, the gravitational force is also different at different positions. The closer to the center, the stronger the gravitational force, and the more celestial bodies and matter will gather. Whereas far away from the galaxy, the gravitational force is weaker, and there are naturally fewer celestial bodies and matter.
The same is true in cosmic space. Gravity will be different in different locations. In areas with weak gravitation, a large amount of matter will disappear. In the end, there is not much matter in this area, forming an “open area”, and the original “open area” is in this way. There are a lot of them in the universe, and scientists call them “holes.”
The diameter of cosmic holes is often very large. Larger holes can reach hundreds of millions of light-years or more. For example, the Virgo Supercluster has a hole with a diameter of more than 100 million light-years. The cosmic wall observed by the Italian astronomy team 15 billion light-years away is actually a cosmic hole, but its diameter is larger, reaching 3.5 billion light-years.
Of course, a hole does not mean that there is no matter in it. It is just that celestial bodies and matter are very scarce and cannot be observed with our current observation technology. Therefore, in the lens of an astronomical telescope, it looks like a huge area with nothing. Although the cosmic wall is hollow, many people feel sorry for the result, but the discovery of this huge hole still has a great effect on our understanding of the universe. Significant significance.
