Super Battleship Reborn
Chapter 254 Star Surface
Through the lenses of these dedicated detectors, Xiao Yu carefully observed the surface of the star. . As the distance approaches, the star becomes more and more luminous and larger.
At a distance of only 50 million kilometers, the star looks like a millstone. At a distance of 20 million kilometers, it has become the size of a house and is so bright that it cannot be seen directly. When the distance was reduced to three million kilometers, it already occupied Xiao Yu's entire shot. Of course, beyond this distance, Xiao Yu's detector has already hidden to the side covered by the ghosts to avoid the amazing energy of this star.
In fact, strictly speaking, a star, like a gas giant planet, has no clear boundaries. The farther they are from the main star, the thinner the material is, and the closer the distance is, the higher the material density is. It is a gradual process from low to high material density. They do not have solid surfaces like rocky planets.
Xiao Yu speculated that at a distance of three million kilometers from this star, if there were no ghosts here, these detectors of his should have already touched the surface atmosphere of this star.
Above this distance, the radiant energy of the stars has reached an astonishing level, and various high-energy charged particle streams, that is, stellar winds are extremely strong. Equipment will be paralyzed. The light here is so intense that it almost drowns matter. Above this distance, if the influence of the gravitational force of the stars is excluded, the propelling force of these light rays alone can accelerate Xiao Yu's instrument from rest to a speed of tens of kilometers per second. It is conceivable that the luminosity here How strong is it.
This is light pressure. Photons have no rest mass, but they carry energy in motion. In the era of the earth, human beings also planned to use the light pressure of the sun to start interstellar travel, but it was not really implemented due to various reasons. After Xiao Yu has mastered the technology of controllable nuclear fusion, there is no need to use light pressure.
This star is only a moderately small star. There is even a class of giant blue stars in the universe, and their luminosity can even reach or temporarily exceed the Eddington luminosity limit, that is, the outward pressure of the light pressure exceeds the gravitational force of the star itself. When this happens, a large amount of stellar matter will leave the star under the push of its own light pressure and be thrown into space. Because the shedding of matter will reduce the luminosity of the star, its luminosity will be reduced below the Eddington luminosity limit. This kind of giant star maintains its own dangerous balance in this state.
Just thinking about that kind of crazy star makes Xiao Yu's heart shudder. During the space voyage, Xiao Yu would rather go around a hundred light-years rather than get close to them. Those kind of stars are really not to be trifled with, and they might explode at any time, turning directly into a black hole. At the same time, by the way, wipe out all creatures within hundreds of light years around.
Fortunately, in the universe, there are only a few such stars, so Xiao Yu doesn't have to worry about supernova explosions affecting himself all the time.
After the distance between Xiao Yu's detectors and the star was shortened to three million kilometers, Xiao Yu began to manipulate his detectors to accelerate in reverse. This is a necessary procedure, if you don't do this, the gravity of the star will continue to accelerate them, and eventually cause them to collide directly.
Because of the angle, at this moment, Xiao Yu sees the star as just a crescent crescent, but the leaked crescent heats up the surface of Xiao Yu's detector two million kilometers away. To the extent of more than three hundred degrees Celsius.
Above this distance, the specific shape of this crescent cannot be distinguished on the full-light photo, because its light is too strong,
As a result it looks like an irregularly shaped multi-pointed star. Only after reducing the luminosity by hundreds or thousands of times can it barely see its original shape.
Fortunately, all of Xiao Yu's detectors adopted ultra-distance communication, and all the internal instruments of the detectors were equipped with the most powerful anti-radiation materials, so they were not affected by the radiation of this crescent moon.
This is the closest Xiao Yu has been to a star in more than 10,000 years. The last time it was so close to a star was when it was traveling around the sun in the solar system. In the previous binary star system, it was impossible to count, because the brown dwarf cannot be regarded as a real star at all.
The power of a star, you will never experience it unless you get close to it. Xiao Yu sighed secretly in his heart.
Xiao Yu aimed the probe's camera lens at the half of the star covered by ghosts. What Xiao Yu saw was a vast black plain. That's right, under the cover of the ghost clan, the surface of this star has become an extremely flat plain with basically no undulations.
The stellar atmosphere here is also gone. Because of the ghost family's coverage, only half of the star's atmosphere is left. Xiao Yu speculates that the stellar atmosphere on this half may have been frozen into a liquid or solid due to heat insulation, and eventually fell onto the surface of the star.
This is the generosity of the Ghost Clan. The stars without a fixed surface were forced out of a surface by the ghosts.
After continuing to approach, Xiao Yu realized that all his previous preparations were in vain. Here, as the ghosts said, all heat and all radiation are isolated by it. Therefore, on this side of the star, except for the strong gravitational force, there is no difference from the interstellar space, just as cold and deserted.
After the distance was reduced to 200,000 kilometers, Xiao Yu could no longer see the whole picture of the star. In Xiao Yu's eyes, everything is that kind of black without much ups and downs, endless, vast and boundless plain. Above this distance, the crescent-shaped stellar body was also blocked behind because of the angle.
Senior, here I come. Xiao Yu sent a radio broadcast to the star.
The ghost family's reply came quickly: The surface of the stars here has been pressed into a solid by me, you can land here at will. After landing, do whatever you want to do research, don't bother me for a short time, I'm very tired ,need to have a rest.
Okay, senior, go and rest. Xiao Yu said respectfully.
I don't know why, but at this moment, Xiao Yu remembered the old cat he raised when he was on the earth. Every winter, this old cat always leans lazily by the fireplace, keeps its eyes closed and refuses to move. Every time it has to rely on the servant to bring cat food to its mouth, it is willing to eat a little. , continue to rest after eating.
At that time, Xiao Yu knew that this old cat would not live long. The facts did not exceed Xiao Yu's expectations, and the old cat died before it even survived that winter.
Even if you are as strong as you, is there such a time when you will be old and dying? Looking at this ghost family who was once strong and brilliant, but now just looks like an old man, Xiao Yu had mixed feelings in his heart.
Thousands of dedicated probes each chose a different location to land on the star's surface. The gravity here is hundreds of times stronger than that of the earth. If a person lands here, his bones will be crushed in an instant, and his body will be crushed into a thin sheet under his own weight. However, Xiao Yu's detectors have taken into account the environment here at the beginning of their manufacture, so they will not be affected by these strong gravitational forces.
It wasn't until after landing on the surface of the star that Xiao Yu discovered the real situation here. Under the feet of Xiao Yu's instrument, there is a layer of black translucent object that looks very thin but is extremely tough. Through this layer of objects, you can even see the surface of the star at close range.
These things attracted Xiao Yu's full attention. There are not many opportunities to observe the surface of stars at such a close distance, and it can even be said that there are not many opportunities for Xiao Yu to cherish it.
This translucent black film should be the body of the senior ghost clan. The senior ghost clan said that it is illogical and does not exist in this universe, but an existence with zero total mass and total energy. It's a miracle that it can appear solid, yet be so tough that not even a single star can be damaged.
When the senior Ghost Clan was at its strongest, it is estimated that even natural neutron stars or white dwarfs could not damage its body structure. Presumably, a seriously injured and dying sixth-level alien beast could survive on the surface of the white dwarf. They survived the world, not to mention the seniors of the Ghost Clan who can go head-to-head with the Neutron Battle Star.
Xiao Yu thought secretly.
Through this translucent black film, Xiao Yu carefully observed the stellar matter below it.
This black film seems to have an extremely superior function of blocking light. Through its filtration, the stellar matter presented in front of Xiao Yu is slightly yellow. This is in line with Xiao Yu's previous inference based on the principle of black body radiation. According to the principle of black body radiation, a star with this mass and temperature should be yellow.
These yellow, fluid-like stellar substances are surging angrily at the feet of the instrument made by Xiao Yu, like a crazy sea. However, no matter how violent their actions are and how powerful their energy is, they are still unable to break through the barrier of this black film. At most, it is a small bulge that raises the black film up to a height of no more than 100 meters, which looks like a small earth mountain appearing on the black plain.
At this moment, the strength of the ghost clan is fully revealed.
