The sun has been burning for 5 billion years, why hasn t it been extinguished?

The sun has been burning for 5 billion years, but it has not been extinguished because the sun does not release light and heat by burning matter, or through chemical reactions, but through the release of energy。This energy release is formed by a very huge nuclear fusion, we all know that nuclear fusion, which is currently one of the most powerful ** in the world, such as a nuclear bomb, and the energy it produces by nuclear fusion is very huge, which is unimaginable to human beings.

We all know that the sun is the mother of the earth, and if there is no sun on the earth, there would be no life on the earth, because the sun provides the light and heat that life needs. The sun is like the mother of mankind, providing a constant source of energy to the earth. In ancient times, there were many tribes who used the sun to represent the gods, which is the reverence of human beings for the sun.

With the progress of science and technology, human beings are exploring the universe and exploring the sun, and the energy technology is getting higher and higher. We also know that the sun is a kind of planet, and the earth will revolve around the sun, and the sun is like the boss in the solar system, and the nine planets will revolve around it. Many people will wonder why the sun has been burning for about 5 billion years, so why can the sun continue to burn without extinguishing?

And when is the limit of the sun's burning?

We all know that anything that burns it must need matter, and no matter is definitely not combustible to burn, and scientists used to believe that the sun needs matter to burn, and this substance is the energy provided by the occurrence of chemical reactions. With the development of modern technology, scientists have discovered that the reason why the sun can continuously provide light, energy and heat to the universe is not through combustion, but through the release of energy. The release of this energy is quite a kind of formation and release of nuclear fusion, we all know that the missile is currently one of the most powerful in the world, and the energy released by the missile is incalculable by human beings.

The missile is quite like a small sun, and from the power of the missile, we can imagine how powerful the sun's energy is.

Scientists are not saying that the life span of the sun should be about 10 billion years, and now the sun is only 5 billion years old, which is the middle age period, and it will be 5 billion years long when it is extinguished.

Actually, the sun doesn't burn. The sun we see is only a physical change, and there is no flame. The sun is meant to change by making physical changes. Transmit energy to the outside world. to ensure that the creatures on other planets can react normally.

First of all, the sun burns because nuclear fusion occurs on the surface of the sun, nuclear fusion consumes less energy and releases more energy, and secondly, the energy required for solar combustion will be replenished from other places.

Everyone is wondering why the sun has been burning for 5 billion years and hasn't been extinguished. In fact, it is not the sun itself that burns, but the effect of the nuclear fusion reaction, which is a fundamental physical change, and is completely unrelated to the chemical change of combustion.

The sun's continuous flow of light and heat to the Earth is not caused by combustion, but by the release of more complete and larger nuclear fusion. The sun has been burning itself all the time, it can be said that it is halfway through its lifespan, and it may be 5 billion years later, the sun will be extinguished and there will be no more light and heat.

This is because the sun does not burn fuel, it is not the energy produced by chemical reactions, it is a release of energy, just like nuclear fusion, which is a very large and perfect kind of nuclear fusion.

At present, the earth on which human beings depend is suffering from relatively serious environmental pollution, and if human beings do not protect the earth in time, it is a question whether human beings can continue to live on the earth for 500 million years, let alone 5 billion years. Therefore, the most important thing for human beings at present is to protect the earth and manage the earth's environment, so that human beings can survive on the earth for a long time.

The sun has been burning for 5 billion years, but the reason why it still can't be burned is because the sun is very big and has a very long lifespan, so 5 billion years is not a long time for the sun.

Because in fact, the loss is very small, and experts have said that it can be burned for another 5 billion years. So the transformation process is very slow.

Because the life of the sun is so long, its huge size makes it have a lot of core fuel energy, with a lifespan of about 10 billion years, and now it has only completed half of its life.

This is because the sun is really too big, its life span is calculated in tens of billions of years, according to relevant scientists, the sun will be about 5 billion years later, its internal hydrogen elements will be exhausted, will cool down into a white dwarf, at this time, will slowly extinguish.

That's because the volume of the sun itself is very large, and it often undergoes nuclear fusion reactions, and the sunspots on the surface will occur, but the mass of combustion is only a little bit of his mass.

The sun has been burning for more than 4 billion years, why has it not been extinguished, and how long can it continue to burn?
