Xiao Yu knew about the primordial black hole, but before, Xiao Yu only regarded the primordial black hole as something no different from ordinary black holes, and did not pay special attention to it - even if it is the primordial black hole, isn't it also a black hole?
It also has the horizon boundary and indicators such as angular momentum, mass and charge. -{2}{3}{w}{x}
But at this moment, after obtaining this information from the Mechanical Civilization Group, Xiao Yu knew the differences between the primordial black hole and ordinary black holes. These differences made Xiao Yu understand that the primordial black hole was very important to him.
"After the Big Bang, no, it should be called the first time that there were rules in the universe, the primordial black hole was the first batch of stars to appear. The characteristics of the black hole caused it to only allow matter or information to enter, but not allow information to escape.
It comes out from the inside. Excluding the primordial black holes that were destroyed due to information storms and black hole explosions, the primordial black holes that have survived until now will definitely hide many mysteries of when the rules first appeared. What are the rules and the essence of the rules?
What it is, maybe the answer can really be found in the black hole of Taichu." Xiao Yu thought silently.
From the appearance, there is no difference between the primordial black hole and ordinary black holes. There are more than tens of millions of black holes in the universe, so how to distinguish the primordial black hole from these tens of millions of black holes? Xiao Yu can't just see one
Black Hole just ran over and analyzed it. Even if Xiao Yu had the energy, Xiao Yu would not do it like this.
Then, Xiao Yu must have a benchmark to distinguish the primordial black hole from the ordinary black hole.
There is a very trustworthy benchmark placed in front of Xiao Yu, and that is the mass of the black hole. The dividing line is two times the mass of the sun and 10 billion times the mass of the sun. Any black hole with a mass within this range, it
There is a very high probability that it is not a primordial black hole, but an ordinary stellar black hole or a collective black hole formed by the collision and fusion of many stellar black holes. The mass is not within this range. That is, it is less than twice the mass of the sun, or greater than 10 billion
A black hole with a mass twice that of the sun has a very high probability of being a primordial black hole.
But there are exceptions. Black holes will continue to reduce their mass through Hawking radiation, and the Hawking radiation rate is inversely proportional to mass. That is to say, the greater the mass of the black hole, the slower the mass will be lost by Hawking radiation, and vice versa. This
As a result, the primordial black hole with a mass below a certain mass has disappeared into the universe due to Hawking radiation. After calculation, Xiao Yu knows that the mass standard is about 100 million tons. According to conversion, the event horizon radius of this black hole is only less than
One femtometer. This is smaller than an atom. If Xiao Yu really finds this tiny black hole, it can only prove one thing. This is not a primordial black hole, but one created by an intelligent civilization.
By measuring the mass of the black hole, Xiao Yu can greatly narrow the scope of his search. Measuring the mass of the black hole is an extremely simple matter for Xiao Yu.
Xiao Yu doesn't know how many primordial black holes there are in this three-dimensional universe. But I guess the number will not be too small. And Xiao Yu also has the most powerful weapon to find primordial black holes. His seed network is constantly expanding.
.
After Xiao Yu received this information from the Mechanical Civilization Group, Xiao Yu had already launched his own seed network. The seeds in the seed network were built using the technological ideas of Mechanical Civilization. These tiny particles can not only continuously replicate themselves
, they can also be brought together to form any machinery and instruments that Xiao Yu wants. Now, they have been combined with each other to form countless tiny gravity measurement instruments, optical observation instruments, radio waves, and space observation instruments. Gravity measurement instruments
The gravitational strength of a certain area can be measured, and the optical observation instrument can measure the mass of visible matter in the area, and compare this data with the data observed by the gravitational observation instrument. If the two data do not match, then
It proves that there is probably an invisible black hole in that area.
In addition, optical observation instruments can also observe the existence of black holes through optical effects such as gravitational lensing. Radio wave observation instruments can observe the intensity and changes of rays in a certain area to find black holes. Space Observation
The instrument looks for traces of black holes through changes in the spatial level.
Xiao Yu believes that with the search of his seed network, any black hole, no matter how small it is or how hidden it is, will eventually be found by himself. As long as the black hole is found, the next step will be simple.
The purpose is to measure the mass of the black hole to confirm whether it is worthy of continued observation. If there is, further observations will be made. If not, the black hole will be numbered and abandoned. No more instruments will waste resources on it in the future.
So far, Xiao Yu's seed network has spread to nearly 100 million light-years away, and Xiao Yu has launched close search activities within this spatial scale. Moreover, Xiao Yu's fleet is still moving forward, and the scope of the seed network is also
Continue to spread. Xiao Yu's search for the Taichu Black Hole will become more and more efficient.
In addition to searching for the primordial black hole, Xiao Yu still has many things to do. The most urgent thing at the moment is to absorb and digest the numerous scientific and technological information harvested from more than 80 eighth-level civilizations of the Mechanical Civilization Group. Mechanical Civilization Group
The eighth-level civilization among them covers almost all types of eighth-level civilizations in the universe. Being able to become an eighth-level civilization has proved that this civilization has developed technology in this direction to the limit and even came into contact with the rules. After absorbing and digesting these
After obtaining scientific and technological information, Xiao Yu will become a truly top-level eighth-level civilization with all-round development.
Whether it is architecture, music, micro, macro, universe or extreme stars, Xiao Yu has the most profound attainments. And after smelting all these technologies into one furnace, the power they explode will be far from
It's as simple as one plus one. Although it still cannot become a ninth-level civilization, Xiao Yu's strength will still improve a lot.
"Think about it, after I fully master these technological data, even the rebel camp will no longer be my opponent if they don't have logical weapons." Xiao Yu stood in front of the porthole of the Humanity spacecraft and looked at it calmly.
The endless dark universe outside the window, I thought lightly.
There is a strange black sphere slowly rotating in Xiao Yu's hand. This black sphere undoubtedly has extremely strong gravity, but it is extremely docile in Xiao Yu's palm. It floats in the sky above Xiao Yu's palm.
,Quietly.
This is a black hole, a small black hole. Its event horizon radius is about seven centimeters. And the event horizon radius of seven centimeters means that the mass of this black hole is about 472 trillion tons. This number,
It is about eight times the mass of the Earth.
At this moment, Xiao Yu holds eight earths in his hands. After breaking away from the computer and integrating music civilization, Xiao Yu's body already has the strength of an eighth-level peak alien beast. With the strength of an eighth-level peak alien beast,
It is not a big deal to have the strength to do this, it can even be said to be a very simple matter.
The mass of this black hole is not within the range defined by Xiao Yu, which means that it may be an primordial black hole. In fact, through analysis, Xiao Yu also confirmed this. This is Xiao Yu's huge seed
The network found a primordial black hole in a medium whirlpool river system about three million light years away from Xiao Yu at this moment. After finding this primordial black hole, the seeds in the seed network immediately combined into
He obtained a Star Gate instrument and delivered it to Xiao Yu as quickly as possible so that Xiao Yu could carry out subsequent research.
"This is the primordial black hole. It was born more than 10 billion years ago. It was born together with the rules of our universe. It has witnessed the development of our three-dimensional universe to what it is today. In a sense, it is the same age as our universe.
." Xiao Yu lowered his head, looking at the small black hole in his hand in trance, thinking silently.
Xiao Yu noticed many things that have nothing to do with science from this primordial black hole, such as vicissitudes of life, such as antiquity. Millions of years in a hurry, in the eyes of this primordial black hole, are just fleeting. For it, time
It seems meaningless.
When the rules of the universe were first born, perhaps it was because the density of matter in a certain area was too high, so they did not have the chance to go through nuclear fusion or star explosions, and directly aggregated into such a black hole. Its luck
Maybe it's not so good. At least, it didn't find enough food during the next 13 billion years. Otherwise, it wouldn't still be as tiny as it is now.
body shape.
Xiao Yu's hand moved slightly, and immediately, the horizon boundary of the black hole began to shrink continuously. Obviously, the speed of light around the black hole was increased. As the speed of light increased, as the size of the black hole continued to shrink,
Things began to be released that were hidden inside the black hole and had never been exposed to the outside for more than 13 billion years. Those things were so wonderful that even Xiao Yu could not fully understand them. Xiao Yu
Yu knew that these things were probably the things he was pursuing so hard.
But these things are not complete. Moreover, inside the primordial black hole, in addition to these key things, there are many useless and messy things. It may be a piece of light, or a piece of information, or something
By chance, this black hole swallowed up a grain of cosmic dust. These things are witnesses of the long time that this primordial black hole has experienced since its formation. They originally had no chance to see the sky again, but now, they all appear in Xiao
