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.

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.

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.

The flashbacks in the movie Wandering Earth 2 were the various future possibilities deduced by MOSS. As a 550 series super quantum calculator, MOSS had super deduction ability and might already have independent consciousness and absolute rationality. In these flashbacks, like Liu Peiqiang burning MOSS, this indicated that it was a fixed future result. No matter how the process changed, it would eventually happen (echoing the Wandering Earth 1). There was also the bald Tu Hengyu on the moon. This might mean that the moon had not been bombed. Tu Hengyu had contracted a disease like radiation sickness and his hair had fallen off, just like Han Duoduo's condition after she fell ill. In addition, the white-haired Zhou Zhezhi, who was holding the detonator, meant that if Yaya's consciousness had not been uploaded and the moon's engine had not stopped, the nuclear bomb would not have been confiscated, and this would have happened. By grasping a massive amount of information that humans could not fully grasp, MOSS used its super deduction ability to deduce what the future of mankind would look like based on the current situation. These flashbacks were the scenes in the future that were deduced. These flashbacks helped the audience understand the complex timeline and the possibilities of different events in the movie.

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!
