Wandering Earth, Sun, After Helium Flash
In the world of " Wandering Earth," after the solar helium flash, the Earth drifted in the lonely and cold universe. Humans who had lost the warmth of the sun had to face the threat of the universe. People needed to use thermostats to move on the surface, and the actions and construction on the surface required huge amounts of energy and resources. It was designed for surface survival, underground cities, artificial intelligence bodies, the Heaven Mending Plan, and so on. Wandering Earth 2: Adventures Again is not enough.

Helium Flash on the Wandering Earth
In "Wandering Earth 2,""helium flash" referred to a momentary phenomenon of helium fusion. During the evolution of a star, the hydrogen in a star like the sun would release energy through nuclear fusion to produce helium. When the hydrogen in the central region was completely exhausted or the hydrogen combustion in the shell stopped, the helium fusion reaction would suddenly start. This was the helium flash. It released a large amount of energy in a very short period of time. After the star had a helium flash, the helium could continue to burn slowly, and the helium flash might happen more than once. Judging from the Sun's situation, the Sun's life span was about 10 billion years. It had already existed for about 4.6 billion years and was in the main sequence stage. About 5 billion to 6 billion years later, the hydrogen in the core of the sun would be exhausted. The helium nucleus accumulated in the core would become larger and larger, causing the core to shrink. The density, pressure, and temperature would rise sharply, igniting the nuclear fusion of helium and causing a helium flash phenomenon. Since helium nuclear fusion released more energy than hydrogen nuclear fusion, the radiation pressure would cause the outer layer of the star to expand outward, increasing the size of the sun, lowering the surface temperature, and becoming a red giant. When the sun evolved into a red giant, it would swallow Mercury and Venus. The solar wind would take away a large amount of material, causing it to lose about 30% of its mass. The gravity on Earth would be weakened by about 30%, and the Earth's orbit would be further away from the sun than it was now. Moreover, the extremely violent celestial activity of helium flash could destroy the earth's ecology in an instant. Watching "Wandering Earth 2" was not enough.

Wandering Earth 2078 Solar Helium Flash Crisis
In Wandering Earth 2, it was mentioned that humans would face a solar helium flash crisis in 2078, which would destroy the Earth. Solar Helium Flash was a series of deflagrations that occurred when the sun became a red giant and the helium core inside the sun was compressed into a dense material state. Each solar helium flash lasted for a few seconds or minutes until the solar helium core became normal matter. Currently, the Sun was in the main sequence stage and was undergoing nuclear fusion of hydrogen, which would transform into helium. When the hydrogen was completely burned out, the core of the sun was almost entirely made up of helium. When the temperature of the helium core reached about 20 million degrees Celsius, the hydrogen outside the helium core that had not participated in nuclear fusion would undergo nuclear fusion. The sun's volume would expand into a red giant, large enough to swallow Mercury and Venus. When the sun entered the red giant stage, the internal helium core gradually entered a state of dense matter. When its mass reached 0.45 suns, the helium core would undergo a solar helium flash from the center. The film also showed that the mastermind behind this series of crises was MOSS. It created many crises, including the 2078 solar helium flash crisis, in order to overcome mankind's obsession with history, the present, and the future. By creating crises, it forced mankind to unite and continue the best human civilization. Wandering Earth 2: Adventures Again is not enough. Everyone is welcome to click to read the novel!
Is the Wandering Earth 3 the Solar Helium Flash Crisis?
According to the original novel, humans on Earth were divided into two factions. Many people doubted the original purpose of letting the Earth leave the solar system. The question of whether the sun would really be destroyed led to a conflict between the two factions. This period of history was named the "Helium Flash Crisis." However, from a scientific point of view, the sun's helium flash was not a natural phenomenon in stellar evolution theory, but a fictional setting in science fiction movies. At present, the sun was unlikely to have helium flashes. Therefore, in Wandering Earth 3, the "solar helium flash crisis" was part of the story setting. From a scientific point of view, it was not a real crisis. Wandering Earth 2: Adventures Again is not enough. Everyone is welcome to click to read the novel!
Wandering Earth, Three Suns, Helium Flash
In the original novel of Wandering Earth, the solar helium flash was the core plot. From a scientific point of view, during the evolution of the sun, when the helium in the core reached a certain density, it would trigger a helium flash, which was an extremely intense thermonary-nuclear reaction. According to astrophysics, helium flashes would definitely occur in the distant future, but it was generally believed that it would only happen after at least 5 billion years or even 7 billion years. However, for " Wandering Earth 3," in a narrow sense, it was likely to shoot a plot related to the solar helium flash crisis. According to the settings in the work, once a helium flash occurred, it would bring about a huge disaster. A large amount of helium would fuse almost at the same time, forming a huge explosion, releasing a huge amount of energy in a short period of time. The sun would become brighter and expand rapidly in a short period of time, spewing a large number of solar storms into space. This would cause many negative effects on Earth. The strong light would cause the vegetation on the surface to dry up, the sea water to evaporate, and animals to die. The strong solar storm would break through the Earth's magnetic field and sweep through the atmosphere. Moreover, helium flashes could happen many times, causing the sun to eventually expand into a red giant that swallowed the Earth's orbit. In the story of " Wandering Earth," humans chose to escape the solar system with Earth to avoid helium flashes. Wandering Earth 2: Adventures Again is not enough.

Wandering Earth 3 Helium Flash Crisis Will Never Explode
According to current scientific research and theoretical inference, the Sun had passed the stage of possible helium flashes. Helium flashes could occur in the age range of 1 billion to 3 billion years, and the probability of occurrence was between 10% and 20%. Although helium flash was the core plot in the original novel of Wandering Earth, from a scientific point of view, it was unlikely that the sun would experience helium flash again. However, movie plots often had fictional and creative parts, so it could not be completely determined based on real-world scientific conditions that the helium flash crisis in Wandering Earth 3 would never break out.

The impact of the solar helium flash on the earth
If the sun had a helium flash, it would have a serious impact on Earth in many ways. From the perspective of energy release, the helium flash released hundreds of billions of times more energy than usual in a very short period of time (a few seconds). The energy released was equivalent to the sum of the energy released by hydrogen nuclear fusion for millions of years. The release of this enormous energy would make the sun brighter in a short period of time, while the sun would rapidly expand and spew a large number of solar storms into space. In terms of the direct impact on the Earth's surface, the strong light would cause the vegetation on the surface to dry up, the seawater to evaporate, and animals to die. The strong solar storm would break through the Earth's magnetic field and directly sweep through the Earth's atmosphere. It could evaporate the seawater in an instant and melt the surface rocks into pulp. The overall temperature of the Earth would also rise to an extremely terrifying degree, causing the Earth's environment to become as harsh as Venus. This would cause the Earth's ecological system to be destroyed in an instant, and all life would be unable to survive. In the long run, the sun would become a red giant after a helium flash, and its volume would continue to expand. After the sun became a red giant, although the Earth would not be immediately swallowed by the sun itself, under the effect of tidal gravity, the Earth might be swallowed by the outer atmosphere of the sun.

Will the solar helium flash destroy the earth?
If the sun had a helium flash, it would have a huge negative impact on the earth, possibly leading to its destruction. During the solar helium flash, a huge amount of energy would be released in a short period of time. The sun would rapidly expand and spew a large number of solar storms into space. The strong light would cause the vegetation on the surface to dry up, the seawater to evaporate, and animals to die. The strong solar storms could break through the barrier of the Earth's magnetic field and sweep through the Earth's atmosphere. Furthermore, the helium flash could happen more than once. As the abundance of helium in the sun continued to change, it would cause the sun to continuously expand and eventually expand into a red giant. Its volume would increase by millions or even 100 million times, and it would engulf the Earth's orbit. If the Earth was still in its original orbit, it would be equivalent to being swallowed by the Sun. However, according to current astrophysics knowledge, the solar helium flash would only occur after at least 5 billion years, or even 7 billion years. There was also some debate about the destructive power of the helium flash on the surrounding planets, because the energy produced by the helium fusion would cause the star to expand. When the star expanded, it might absorb most of the energy produced by the helium fusion, so the energy released on the surface of the star might not be very large, but the volume would expand. But even if the helium flash did not have a very strong flash, the strong stellar wind it produced could blow away the Earth's atmosphere, making life on Earth difficult to escape.

Is the wandering earth sun destroyed?
In the setting of " Wandering Earth," the sun had not yet been destroyed, but a helium flash was about to occur. As the hydrogen inside the sun was exhausted in the continuous nuclear fusion, the high temperature and high pressure inside would cause a huge change in the helium element, causing a helium flash phenomenon. This would make the sun extremely unstable, and the unstable heat brought by the explosion would kill all living things on Earth. Therefore, humans migrated the Earth to the vicinity of the neighboring star to avoid the helium flash of the future sun. Wandering Earth 2: Adventures Again is not enough.

Solar Helium Flash Principle
During the evolution of a star (such as the sun), when the hydrogen in the central region was completely exhausted or the hydrogen burning in the shell stopped, a helium flash would occur. The hydrogen inside the star generated helium through nuclear fusion and released energy. As the hydrogen was consumed, the helium gradually gathered in the core of the sun and became electron degenerate, which would continue to push up the temperature inside the sun. When it reached a certain level, helium could undergo a fusion reaction. In small and medium-sized stars, when the density reached a certain level, the atomic shell would be destroyed to form degenerate electron gas. The electron pressure of this degenerate state was independent of temperature, but it increased rapidly with the increase of density. Moreover, its heat transfer properties were similar to metal, making the temperature of the helium core uniform. When the temperature of the helium core rose to the point of helium combustion, the entire helium core region would react at the same time. When the core temperature reached 10 ° K, a helium flash would be triggered. The helium flash process would release a lot of energy in a very short period of time, and the helium flash of a star might happen more than once because the star's position in the giant star region would swing back and forth. At the same time, the production rate of the helium combustion shell itself was extremely sensitive to temperature changes. It had a strong thermal instability and would release a large amount of energy in a very short period of time. Because the helium shell was too thin, it could not absorb a large amount of radiation energy, which might cause helium flashes in the shell. Wandering Earth 2: Adventures Again is not enough.

The power of the solar helium flash
The power of the Solar Helium Flash was reflected in many aspects. In terms of energy release, during the evolution of a star, helium flashes would occur when the hydrogen in the central region was exhausted or the hydrogen in the shell burned out. This process released a lot of energy in a very short period of time. During the evolution of the Sun into a red giant, helium flashes would occur. Helium fusion was not as mild as hydrogen, and a large amount of helium would fuse almost at the same time to form a large-scale explosion. The principle of energy release was that when the hydrogen element was consumed, the helium element in the core of the sun would be in an electron degenerate state. As the helium element gathered and pushed up the internal temperature of the sun to reach the condition of helium fusion, a violent reaction would occur. Judging from the impact on Earth, if the sun had a helium flash, the sun would become brighter in a short period of time. At the same time, it would expand rapidly and spray a large number of solar storms into space. The strong light would cause the vegetation on the surface to dry up, the seawater to evaporate, and animals to die. The strong solar storms could break through the barrier of the Earth's magnetic field and sweep through the Earth's atmosphere. Moreover, helium flashes did not only happen once. As the abundance of helium in the sun continued to change, the sun continued to expand and could eventually engulf the Earth's orbit. Even if the Earth was still in its original orbit, it would be " swallowed " by the sun. However, there was a debate in the astrophysics community about the magnitude of the energy released by the helium flash and the destructive power of the surrounding planets. Because helium fusion occurred inside the star, the energy generated caused the star to expand and the star absorbed most of the energy. Therefore, the energy released on the surface of the star during helium fusion might not be as large as imagined, but even if there was no strong flash, the strong stellar wind during the solar helium flash would blow away the Earth's atmosphere. It caused the life forms on Earth to be unable to escape misfortune. Wandering Earth 2: Adventures Again is not enough. Everyone is welcome to click to read the novel!
