For the universe, in many people’s cognition, it is a vast and boundless space. The modern theory of the universe believes that it originated from the big bang, the starting point 13.8 billion years ago. The big bang gave birth to the universe, and the universe after its birth is also expanding rapidly.
Through the Big Bang theory, we can see that the universe is an infinite space with no boundaries and no boundaries. However, an astronomical science team from Italy published their latest discovery in the journal “New Scientist”, that is, there is a cosmic wall about 3.5 billion light-years in diameter in the universe.
If this cosmic wall really exists, then the modern theory of the universe may be rewritten, then does this cosmic wall really exist? Cosmologists have always disputed whether there is a boundary in the universe. Some scientists have put forward the theory of cosmic bubbles. They believe that different cosmic spaces are wrapped in a huge bubble, and there is a bubble between the bubble and the bubble. Barrier, and this barrier is similar to a cosmic wall.
The cosmic wall proposed by the astronomical research team in Italy has a diameter of about 3.5 billion. In this largest area of light-years, the temperature may be close to 0 degrees, and the common matter in the universe basically does not exist here, that is to say , Here is a silent dead place.
So does such a cosmic wall exist? On the basis of modern cosmic theory, this cosmic wall cannot exist. Although modern theories believe that this cosmic wall cannot exist, there is a silent space like the cosmic wall in the universe.
This kind of cosmic space has a name in modern cosmological theory, that is, cosmic void. I believe many friends are aware of universal gravitation, and universal gravitation is the core power of the movement of the universe. Stars, planets, and other celestial bodies are formed under the condensing of gravitation, and planets of varying numbers are formed under the action of gravitation. One by one galaxy.
However, the universal gravitation of different universes is also different. The denser the material, the stronger the gravitational force. Under the action of gravitation, these materials continuously gather to form stars, planets and galaxies, and the gathered material has stronger gravitational force. Constantly absorb the matter around the galaxy.
The gravitational force of the space with sparse matter is naturally weaker. The matter in this space area cannot resist the gravitational force of other densely-material areas, and a large amount of matter begins to lose continuously, and finally forms a “empty area” which is called cosmic voids in astronomy. , And the essence of the cosmic wall is actually this kind of cosmic void.
The Milky Way belongs to the Virgo Supercluster, and within this supercluster, there is a huge hole with a diameter of 100 million light-years. The diameter of the cosmic hole in the constellation of Eriocheir is about 3.5 billion light-years in diameter. So the so-called cosmic wall observed by Italian astronomers is actually a huge cosmic hole.
There are many cosmic holes like this in the universe. Hubble has exposed the deep space of the universe many times. Scientists merge the photos produced by the exposure together, and we see a beautiful deep space world.
In this photo, in addition to seeing a large number of galaxies, there are many dark regions between galaxies and galaxies. These dark regions are cosmic holes. They are all very large in diameter, and they are basically in More than 100 million light years.
Seeing this, I believe many friends have already understood that the cosmic wall observed by Italian astronomers is not a real cosmic wall, so does the cosmic wall really exist at all? For this question, it is difficult for scientists to give a definite answer.
Although the modern theory of the universe believes that the wall of the universe does not exist, science is constantly advancing, and mankind’s knowledge of the universe is also constantly being updated and advancing. We still can’t really determine whether the universe is big or not. Is there a realm in the universe?
If the universe has a size and boundary, then a cosmic wall may also exist. More importantly, scientists have also proposed a multiverse conjecture. If this conjecture is correct, then there will be a space barrier between different parallel universes, and this space barrier is the real wall of the universe.
Of course, it is necessary to prove that cosmic pluralism cannot be achieved by the current technology. It also requires us to continuously develop technology and continuous efforts. Perhaps in the infinite future, we will find the real cosmic wall. At that time, we will pass through the cosmic wall. Perhaps we can understand the world outside the universe, and we look forward to this day.
