IC1101 is the largest galaxy in the observable universe, with a diameter of nearly six million light-years. In the observable universe, where the diameter of a river system is usually measured in ten thousand light-years, a river system with such a huge diameter appears to be
Something unusual.
In fact, this river system is indeed unusual. Xiao Yu found that his current theory of river system evolution is difficult to explain why such a huge river system was formed.
Of course, it is still unknown whether there is a larger river system than IC1101 in the unobservable universe, but one thing is certain, this is a big thing, and an unusually big thing.
Here, one thing needs to be explained clearly. We usually think that the radius of the universe is 13.7 billion light-years. The "universe" referred to here is only the scope of the observable universe, because the universe has only been born for 13.7 billion light-years.
In 1.7 billion years, if we calculate our visible range based on the speed of light, the radius of our observable universe is also 13.7 billion light years. It does not mean that beyond this 13.7 billion light years distance
Then there will be nothing. There may be stars and galaxies there, but Xiao Yu cannot know the specific situation there, because the light carrying the information there has not yet reached Xiao Yu. There, it belongs to the unobservable universe. The observable universe
Together with the unobservable universe, they form our huge three-dimensional universe.
This will lead to another contradiction - the speed of light is the upper limit of the speed of this universe. It stands to reason that the expansion speed of the universe will not be greater than the speed of light. So, how did they do it? In 13.7 billion years
Among them, has it spread over a range of more than 13.7 billion light-years?
The answer is simple. The expansion of the universe is not an ordinary movement. They are the expansion of space. The expansion of space is not limited by the speed of light.
IC1101 is the king of all river systems within this 13.7 billion light-year radius. Its size is somewhat extraordinary, which can be noticed through a simple data comparison.
The distance between the Milky Way and the Andromeda Galaxy is two million light years, and the diameter of the Milky Way is one hundred thousand light years. The diameter of the Andromeda Galaxy is two hundred thousand light years. In the past, the Milky Way was already the vast universe in Xiao Yu's eyes. The Milky Way
The distance to the Andromeda Galaxy is even more daunting. If there hadn't been the star gate left by the civilization in the direction of travel, it would have been a lot of trouble for Xiao Yu to cross this distance.
However, the diameter of the IC1101 galaxy has reached the order of six million light-years. Put it at the position of the Milky Way, it will include the Milky Way, the Andromeda Galaxy, the Large and Small Magellanic Clouds, the Triangulum Galaxy, etc.
Go in.
It is so huge. At this moment, Xiao Yu is at the edge of this huge river system.
The IC1101 presented in front of Xiao Yu is not too bright - of course, this "not bright" is in comparison with its huge size and numerous stars. In other words, with so many stars and huge
IC1101, which is large in size, should have a much higher brightness than it does now. But it does not. So this means one thing. Most of the member stars of IC1101 in the river system are dim red giants or
Red dwarf star.
Further observations proved Xiao Yu's conjecture. Xiao Yu saw that a large number of old red giants that were huge in size, but extremely low in density and extremely low in luminosity were filled in this river system. At the same time, these red giants were
The mass is also generally low, and stars with a mass greater than twenty times that of the sun are extremely rare.
This means another thing. Over there in the galaxy IC1101, the content of star dust is very small. If the content of star dust is small, the formation of new stars will be slow. Precisely because there are no new stars to replenish,
This situation of mainly old stars only occurs in the galaxy IC1101.
This is a very decayed and decadent situation. It is different from the vitality in the Milky Way. The star structure dominated by red giants means that it is difficult for life to exist here. Because there is no doubt that the surroundings of red giants are not suitable for life.
, and even if life evolves around a certain star, it will be difficult for it to survive the initial period of life safely. Because there are so many red giant stars, it also means that extreme phenomena such as supernova explosions have increased, and the energy released by high-frequency supernova explosions
Strafing fire is enough to destroy any initial life - even the second-level peak civilization. In this case, the third-level civilization will suffer heavy losses.
But this does not mean that there is no life in the galaxy IC1101. Because things always happen by chance, and thanks to the huge number and volume of stars in the galaxy IC1101, and thanks to this huge base, the chance of existence by chance is very high.
Xiao Yu's huge fleet has entered the river system IC1101 and is advancing at high speed here. Xiao Yu has a strong interest in this river system. Xiao Yu tried to further detect the river system IC1101 to solve several questions in his heart.
A doubt. In Xiao Yu’s eyes, Hexi IC1101 is a very qualified, excellent and rare experimental subject.
"I wonder if there are advanced civilizations in this river system? Like seventh-level civilization, eighth-level civilization, etc." Xiao Yu thought silently, "It takes a long time for advanced civilizations like seventh-level and eighth-level civilization to appear.
Based on the situation of IC1101 at the moment, we can know that in the distant past, IC1101 also had a young and glorious stage. During that stage, the galaxy was full of stars of moderate size.
Around these stars, life is very likely to be born. At that time, the river system IC1101 was still very calm, and the environment was very suitable for the development of life. Those life forms probably evolved intelligence and then began to explore the universe."
"Well, if they exist, they must be very powerful. Because they have experienced hundreds of millions of years, or even billions of years. Even if a pig lives for such a long time, it is enough to build a spaceship by itself.
. They have probably entered the category of eighth-level civilization. And below them, as the stars age rapidly and there are no new stars for a long time, the birth process of life in the river system IC1101 is very likely to have a fault. 5
The number of medium-level or sixth-level civilizations may be even rarer than the number of high-level civilizations, and are replaced by a large number of low-level civilizations. These low-level civilizations are constantly being born and being destroyed - the current IC1101 in the river system is indeed
Not a good place to develop life.”
Among the stars in the sky, Xiao Yu is constantly moving forward. What appears in front of Xiao Yu is a slightly dark red sky. This is caused by the influence of a large number of red red giant stars. These red
The stars are very hidden in the dark red sky. They only have a slightly brighter luminosity than the red background. If you look at it with the naked eye, it will be very difficult to distinguish these stars from the background color.
matter.
The scenery here has a slightly unusual and weird atmosphere amid its splendor. The environment here is easily reminiscent of a hell filled with dark red magma. These oppressions are not just reflected in the constant supernova explosions.
——Xiao Yu once observed the emergence of three supernovae in one hour. The emergence of each supernova means that a huge energy sweeps across thousands of light-years of space, killing
It can destroy any weak existence within thousands of light-years. But this is not the most important thing. With Xiao Yu's level of technology at the moment, he can basically ignore the energy of the supernova explosion. The most important thing is the dilapidated overall situation here.
atmosphere.
It is like an old man entering his final years, with destruction everywhere and the smell of death everywhere.
"If there is life here, will their civilization be affected by this atmosphere and evolve into cruelty and bloodthirsty?" Xiao Yu thought silently.
This is a very possible situation. Imagine if the sun in the earth's era was not in the stable state in Xiao Yu's memory, but had helium flashes and explosions from time to time - and it was impossible to say whether it would be a devastating explosion.
When will it come? Under that situation, human society will surely become chaotic and bloodthirsty, because people don't know when their lives will be ended due to an accident.
Of course, this is just Xiao Yu's guess. Xiao Yu is not worried about it. Xiao Yu's strong strength allows Xiao Yu to deal with any situation calmly.
Xiao Yu is setting off towards the core of the river system IC1101. It is the only area in this river system where a large number of stars are formed, and it is the only place where this aging river system still maintains its vitality.
At this moment, in a place unknown to Xiao Yu, there were several rather secret beings communicating with each other.
"The civilization of the universe was destroyed by Xiao Yu."
"We cannot tolerate Xiao Yu's continued existence. He will definitely become more and more powerful and eventually pose a fatal threat to our camp. The spokesperson suppresses different opinions within the camp because of his ridiculous personal feelings, but we
We can't sit back and wait for death like this. We must destroy him while he is still weak at the moment."
"Yes. A lion fights a rabbit with all his strength. We can't make the mistakes of cosmic civilization again. Let us several civilizations join forces and use the most powerful force to crush Xiao Yu. Regardless of whether the spokesperson is willing or not, these things,
We all have to do it."
"We need a reason. Otherwise, our actions may cause divisions in the camp. This is also very detrimental to ourselves."
