The story of sun-1

太陽-2 English

Today I would like to talk about the sun. Have you ever wondered, “Why is the sun burning when there is no oxygen in the universe?”

I have never thought. In the first place, the sun is not burning.

The sun isn’t burning, it’s doing a fusion explosion.

It seems that the birth of the sun was triggered by the star that caused the supernova explosion. In the first place, a supernova is a celestial body that shines due to a large-scale explosion caused by a large-mass star or a white dwarf in a close star system. The explosion phenomenon that occurs just before the celestial body dies is called a supernova explosion. Supernova explosions are said to occur on stars that have more than eight times the mass of the Sun. The explosion is said to look as if a new star was suddenly born.

Now, let’s talk about the sun.

It is believed that the shock waves generated by the material emitted from the supernova explosion hit the surrounding dust and gas clouds, causing gravitational collapse and forming the sun and planets.

The sun, unlike other planets, has no ground. Because it is made of gas.

The surface temperature of the sun is about 6000 degrees, and the corona of the sun is about 2 million degrees. This is something you all learned at school, right?

The constituents are 74% hydrogen, 25% gas such as helium, and the remaining 1% oxygen and carbon.

The definition of the phenomenon of “burning” is to use oxygen to cause a chemical reaction to generate light and heat. You can see that the sun is not burning because it has almost no oxygen.

The hydrogens that make up the sun collide with each other to form helium, which is called a nuclear fusion reaction. In this fusion reaction, enormous energy is generated, and a part of it reaches the earth as light and heat.

From these facts, it can be seen that the sun is not burning and that fusion explosions are repeated.
