How the sun is formed in the world, how the sun is formed

The Sun was originally a planet, and after hundreds of millions of years of changes like Jupiter, it became a star, but Jupiter will shine in a few hundred million years.

The Sun is a star made up of hydrogen and small amounts of elements such as helium and oxygen. It was formed about 4.6 billion years ago, when the primordial clouds in the solar system began to collapse and rotate, eventually forming the Sun and the planets around it.

Inside the Sun, a huge gravitational pull compresses the hydrogen nuclei and causes them to fuse together to form heavier helium nuclei. This process is known as nuclear fusion, in which a large amount of energy and light radiation is released. This energy and light radiation is emitted outwards through the surface of the sun, allowing us to see the bright and warm sun.

In short, the Sun is a spherical object formed by the continuous aggregation and fusion of stellar material over billions of years to form a silver split.

The sun dog is not just formed by the reflection and refraction of light, but is a bright round object on the halo chakra. On the halo, the sun dog can appear on one or both sides of the sun or moon.

The sun is generated, and when the universe is aware, hydrogen condenses into huge clouds, and over time, the clouds gather into a ball of gas, and nuclear fusion occurs inside, which also forms the sun.

The sun is **formed. ** When hydrogen condenses into clouds, the sun gradually collapses inward and nuclear fusion occurs inside the atoms, eventually forming the sun.

The sun was formed by the accumulation of matter in the universe, and it took hundreds of billions of years to get to its current size.

It's a massive volume of interstellar dust that polymerizes under its own gravitational pull.

It's just a star formed by the big ** of the universe.

There is no scientific definition of how it was formed, but it was formed by the transformation of the universe.

First of all, I would like to talk about my understanding of the sun: first, I do not think that it is a balloon, because under such high pressure as its interior, it is impossible for matter to exist in the form of gas, and I think it should be a celestial body that combines gas, solid, and liquid. Second, the energy it has does not come entirely from nuclear fusion, but also from radiation from internal heat sources. This led to the idea of the formation of the sun:

In the ancient space of the solar system, a primordial sun turned. One day in a certain year and month, an alien visitor with a similar mass to the sun collided with the sun, and the jade died. But it is not a complete **, but the impact of the components of the multiple, so, the formation of the same level of the nine planets, due to the size of the problem, the nine planets one by one cooled down, each formed its own small world, but the sun in the center, still exudes primitive energy.

Based on the astrophysical theory of stellar evolution, the modern nebula theory about the formation of the sun was born. The main point of the nebula theory is that there are many huge interstellar clouds in the universe (there are many interstellar diffuse materials in the universe, and the denser places are like clouds, which are called interstellar clouds).

About 4.6 billion years ago, there was a cloud about 5 million times the diameter of the current Sun in the disk-shaped system of the Milky Way. This cloud is composed mainly of hydrogen molecules, but also contains small amounts of helium molecules and dust made up of other elements. The cloud began to shrink rapidly due to the gravitational pull of the material inside, like a high-rise building collapsing in an instant.

After about 400,000 years, a high-temperature, high-pressure, high-density gas ball formed in the center of the cloud, and triggered a reaction in its core that fused four hydrogen nuclei into a helium nucleus, releasing a large amount of heat and light. It is the sun.

The first is a supernova (don't ask me how superstars are formed, you have to go back to the formation of the universe). Then part of the material thrown by the supernova begins to polymerize and rotate due to gravity. The central part slowly coalesced to form the early Sun (infrared star).

Due to the continued gravitational aggregation, the friction of its own matter heats up (just like the friction between the atmosphere and meteorites), and the gravitational effect is acceleration, of course, the friction process will also play a certain role in retardation (it is not appropriate to call deceleration, but it is actually acceleration). Originally, this effect would have continued until it collapsed into a white dwarf (the repulsion between the supersolid atoms of the white dwarf's main substance cancels out the gravitational force). However, due to the heat generated by friction exceeding 2000 degrees Celsius, the hydrogen substance itself becomes active, and the nuclei of atoms (hydrogen nuclei are protons with positive charges) collide with each other (the velocity can cancel out the charge repulsion), fuse into helium, and release a large amount of energy (hydrogen bomb principle).

Energy is released outwards to counteract its own gravitational pull.

Well, that's it, as for the fate of the sun in the future, I won't write about it.
