There is a black crack moving deep in the galaxy 11000 light-years away from the earth. What is it?

Soon after mankind entered the era of science and technology, we successfully realized our dream of flying to the sky and walked out of the earth. When human beings stand in space, they find that the earth is so small and the universe is so vast.

The vast universe is made up of numerous kinds of celestial bodies, among which stars and planets are more common. And each star is attracted by its own strong gravity, leading some planets to form small galaxies, such as the solar system. Many small galaxies form larger galaxies. For example, the galaxy in which the solar system is located is called the Milky way. The diameter of the entire Milky way is 100000 light-years, and it is composed of at least tens of millions of small galaxies.

This is the basic structure of the universe, and there are some special galaxy clusters in the universe, which can also be called cloud clusters. Cloud clusters are very common in the universe. They are of different sizes. From a distance, the cloud seems like a cloud. For example, our solar system is within the Oort nebula, and its diameter can reach about 2 light years. This is also the reason why human beings can not see the solar system It’s too broad.

Generally speaking, the cloud cluster is relatively large, and there are often different number of star systems in the cloud cluster. There is only one solar system in your Oort nebula, which is just a very small cloud cluster. There are many extremely large clouds in the universe, dozens of light-years in diameter, hundreds of light-years or more, and there are many star systems in them.

If the star system is located in the cloud cluster, it will be difficult to observe through the cloud cluster, which will block the line of sight of the astronomical telescope. The formation of cloud clusters is very complex, and some cloud clusters are also very mysterious. For example, scientists once found a very strange black crack like a snake in the depths of the Milky Way galaxy, which is very similar to the cosmic crack, attracting scientists’ interest.

Maybe many people don’t know much about space cracks. In fact, scientists don’t know much about them. Many people may think that our universe is a very stable and smooth space, but this is not the case. If we enlarge the universe many times, you will find that the universe is full of all kinds of small cracks, just like a mirror full of cracks.

So what’s the use of these cracks? Scientists speculate that behind these cracks will be wormholes? We all know that the vast universe takes light years as the basic distance unit. If human beings want to realize the dream of exploring the universe, the spaceship needs super fast speed, and this basic speed is super light speed. However, in the existing physical system, the speed of matter with mass can only be infinitely close to the speed of light.

If our spaceship can’t fly faster than light, we can’t even get out of the galaxy, let alone explore the whole universe. However, according to the normal speed of scientific and technological development, it may take a long time for human beings to achieve superluminal flight. It may take tens of thousands of years or hundreds of millions of years.

So there’s no other way to fly faster than light? The scientist thought of a possible wormhole in the conjecture. Wormhole is a door connecting two universes, through which you can travel quickly, far faster than the speed of light. Scientists speculate that there may be many natural wormholes in the universe, but it is difficult for us to find them. And the space crack is the entrance of the wormhole that scientists suspect. Therefore, scientists will be so excited when they find this black crack 11000 light-years away from the earth.

However, with the continuous deepening of observation, scientists are greatly disappointed that this black crack is not a space crack, it is just a huge cloud cluster forming. At present, there are dozens of solar systems in this cloud cluster, and it is still moving, gathering and absorbing stars and interstellar matter around.

The volume of the cloud cluster is still moving, and it is also growing. Through the astronomical telescope, scientists found that there are many “spots” around it. These “spots” are actually stars that are forming. From this, we can see that this is just a galaxy cluster that was born soon. There are at least dozens of stars forming inside it. When it stabilizes in the future, it will form a huge galaxy cluster.

Of course, it is not so easy for this huge cloud to completely stabilize. It will take a long time to evolve, which may take tens of millions of years or billions of years. When it stops and devours the star, maybe it’s stable, then we can see more clearly what’s going on inside it.

However, tens of millions of years later, human civilization may have already become an interstellar civilization. The distance of 11000 light will be an insurmountable gap for today’s human beings, but for tens of millions of years of human science and technology, it may be just a little farther away, and spaceships can still go to observe.

Through the example that the earth is in the Oort nebula, we may also get a guess that the star system in the cloud cluster is more likely to give birth to life planets and even intelligent civilization. The role of clouds is also a very good protective cover for a living planet. For example, the solar system is protected by the Kuiper belt at the edge, and there is a larger Oort Nebula outside.

With the protection of clouds, it will be more difficult for the celestial bodies outside the solar system to enter the solar system. We should know that there are many kinds of celestial bodies inside the clouds, which will hinder the matter outside the clouds from entering. And another important role of the cloud cluster is to protect the living planet or civilized planet in the cloud cluster from the possibility of being discovered by the alien civilization before it really grows strong.

If an alien civilization observes the direction of the solar system through an astronomical telescope, the first thing it will observe is the Oort nebula. At this time, the clouds will prevent the alien civilization from observing the clear solar system. It is possible that the alien civilization can observe the fuzzy solar system through the clouds, but it will be more difficult to observe the earth again. Heavy barriers will protect the earth .

In the same way, if we find a stable cloud cluster, it will be more difficult to observe the galaxies inside the cloud cluster, and even more difficult to observe the planets inside the cloud cluster. Therefore, it is very difficult to observe and find the planets in the cloud cluster. The astronomical telescope is hindered by the celestial bodies in the cloud cluster, and the light can’t penetrate into it. Naturally, it can’t find the planets that may have life or civilization inside.

To understand the situation in the cloud cluster, we have to send spacecraft or probes to go deep into it. But for the alien civilization, if the astronomical telescope can not observe the possible life planet or intelligent civilization planet, it is difficult to send spacecraft to explore the solar system, unless the earth can be found. It’s the same with human thinking.

If human beings are becoming an interstellar civilization and want to explore and search for living or civilized planets in the universe, we need an astronomical telescope to observe and screen them first, and then we will send spaceships to identify some planets that may have life. If the astronomical telescope can’t observe whether there is a planet with suspected life in a galaxy, isn’t it a waste of time and energy to send a spacecraft to explore? You know, every interstellar voyage takes a long time.
