In science fiction, helium 3 is often depicted as a crucial fuel source for advanced spacecraft. It's seen as a clean and highly efficient energy option that can power long - distance space travel, enabling humans to reach far - flung planets and star systems.

Well, helium is not typically related to comics. Comics are focused on entertainment and storytelling, while helium is just a chemical element. Maybe in some very specific science fiction comics, helium could play a role, but it's not a common theme.

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.

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 reaction equation between helium- 3 (He - 3) and helium (D) was He3 + d = He4 + p + 18.4MeV, but this reaction had a side reaction, which would produce neutrons, and other reactions would occur between the two. For example, the two reactions were: Deuterated + Deuterated ==> Helium 3 + n and Deuterated + Deuterated ==> Tritium + p. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

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!

Often as a super - valuable resource. For example, in some stories, wars are fought over helium 3 deposits on the Moon or other celestial bodies.

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.

Helium was the simplest noble gas. It was very stable and difficult to react with other elements, so it could not react with zincate. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
