Black holes are usually discovered because they produce radiation by gathering gas around them, a process called accretion. The efficiency of high-temperature gas radiating thermal energy will seriously affect the geometric and dynamic characteristics of the accretion flow. Thin disks with higher radiative efficiency have been observed, as well as thick disks with lower radiative efficiency. As the accreting gases approach the central black hole, the radiation they produce contributes to the black hole's rotation and thus the flow of the central extended material system. Accretion is one of the most common processes in astrophysics, and it is responsible for many of the common structures around us. In the early universe, galaxies formed when gas flowed toward the center of a gravitational potential well created by dark matter. Even today, stars are formed by the collapse and fragmentation of gas clouds under their own gravity, and then by accreting surrounding gas. Planets (including Earth) also form around newly formed stars through the accumulation of gas and rock. When the central object is a black hole, accretion is at its most spectacular. In addition to accreting matter, black holes also radiate particles outward through the Hawking evaporation process.
Liu Borong and his wife Yu Jinyu are discussing how spacecraft or space suits that can fight against black holes can go to the center of the Milky Way.
Yu Jinyu proposed about black hole evaporation. Since the density of black holes is extremely high, according to the formula we can know that density = mass plus volume. In order to make the black hole density infinite, it means that the volume of the black hole must be infinitely small, and then the mass must be infinite. Only in this way can it become a black hole. A black hole is a dead star formed after the "death" of some stars. It has an extremely massive mass and a very small volume. But black holes will also die. According to Hawking's theory, in quantum physics, there is a phenomenon called the "tunnel effect", that is, although the field strength distribution of a particle is as strong as possible in places with low energy, even if the energy is At quite high places, the field strength will still be distributed. For the boundary of the black hole, this is a potential barrier with quite high energy, but it is still possible for particles to get out, but it is impossible to do so with your current particle cannons. Unless you develop ultra-high-energy ion cannons and transform them at the particle level, we can't complete these things. We can't complete them without the contribution of science and technology from the people of the Underworld Vegetation.
You and I thought about it together. Although our technology can now make interstellar jumps and open wormholes, it still has to be under certain conditions. The number of light years in the Milky Way is actually twice as long, which means that it is twice the number of light years. Years, which is equivalent to 1.892105668e20, are needed to reach the center of the Milky Way, which is the universe, and the center of the universe is the center of the two galaxies. In other words, the universe is still out of reach for us.
It can also be said that although our current technology has arrived, those aliens would not have been able to come to the earth if their own planet had not become a white dwarf. If it had not been for the Galactic War, after some life planets were replaced, they would not have been able to come. our planet.
Now that we share their technology and imprison them, how could they not be angry, so I am here and in danger.
I think your worries are unfounded! Don’t you think we might be wrong? They couldn’t have come to our planet in the first place or they still want to go back. They have been living on our planet for a long time. In other words, it has been 60 years. Did he colonize just for that day? Now that you have rested, don’t think too much about it and just go and rest first!
It's not too early for you to go to bed early.
Late at night, on the isolated island in the city, there are aliens in the underworld vegetation, with red flames burning in their purple eyes. Some of them put on battle suits and carried weapons, trying to break out of the island.
One of the older men stopped and said: "Karl, stop, do you think you can see us if you go out? Why do those people on earth restrict our movements? Isn't it because our civilization may threaten them? If we rush out now, I guarantee that the cannons from their fort can penetrate your body. Although we can now genetically recombine, we still wrap our genes with flesh and blood."
You mean they can destroy our genetic system.
It will be death if not destruction.
But General, should we just let it go?
No, we still have a chance. Old generals look like thirty-year-old young people. Their genes can limit the functions of the human body, or they can be reassembled like computers, as long as the external parts of the computer are not damaged or worn out.
Karl stopped being impulsive and angry, and his eyes returned to a light purple color.
The old general said, "You have to be patient. There is a saying among the people on earth that three thousand Yue Jia can swallow up Wu. All the hard work has paid off. Millions of Qin passes will eventually belong to Chu."
General, I don't quite understand what these mean. I hope you can explain it.
It means to be patient and secretly accumulate the ability to destroy your opponents. Do you understand?
General, I understand. We will continue to combine the Genesis drive device with the data of our underworld vegetation to develop new weapons. We have named him Genesis Armor. As long as we wear them, we cannot be our opponents.
Carl impulsively wanted to rush out and kill them. Karl has an impulsive personality and seems to hate some of the beliefs he insists on.
The red dots on the surveillance camera were moving towards the central coordinates. It seemed that they were getting closer. The man sitting on the side wearing a military uniform lifted the end of the tea bottle in his hand. Issue an order to the adjutant on his side to activate our Skynet system immediately. I don't believe that their minds can resist our Skynet system. I want them to know what it means to hit an egg against a stone.
A few red dots were approaching in the surveillance system of Xu Tong, but the system machinery sent out seemed to have no effect at all, the operator who was controlling said.
It's good to let this person out, I want to see what skills they have against our weapons.
Three or four people with long knives in their hands had already poured into the skyscraper in their center from the coast by boat. They did not know that the overwhelming waves were coming, and they only had one belief in their hearts to escape. The mechanical group snaked from all directions. Some were running towards them at high speed, some were swimming towards them at extremely fast speeds, some had already climbed onto the top grid, and some were falling from high altitude and pounced on their heads. Karl raised his long knife to block and slashed horizontally to attack them. They killed them, but they were like ghosts that could not be killed. After being exploded, another group would come up, and piles of equipment were blown away by their armor. One of them stood on a high place, with the anger in his eyes trying to tear him apart. He raised a sniper rifle in his hand, and the crosshair in the scope was locked on Karl's shaking head. Always be ready to pull the trigger and blow him up.
