Why can the sun burn for 4.6 billion years without extinguishing?

There are a large number of hydrogen atoms inside the sun, and four hydrogen protons fuse together to form a helium atom. During this time, a small portion of the mass of the 4 protons is lost. Due to the conservation of mass and energy, these masses are converted into enormous amounts of energy, so that the sun radiates up to 10 26 watts.

Enough to burn for 10 billion years.

In fact, the sun burned to the present is more than 4.6 billion years, you must know that the age of the earth is about 4.6 billion years, and the solar system was born because of the sun, and the sun was born after the birth of the earth and other eight planets, scientists believe that the age of the sun should be 5 billion years, and the burning of 4.6 billion years we call is actually calculated by the age of the earth.

Because he has been providing him with hydrogen to burn.

Because the sun is constantly supplied by the energy of nuclear fusion.

Because the burning of the sun does not depend on flames, it is a kind of combustion that occurs due to fusion.

Because he has enough hydrogen there to burn for many years.

Because the solar mouth and fusion energy are very huge.

Because the inside of the sun is always nuclear fusion.

Because it can do nuclear fusion continuously.

Why can the sun burn for 4.6 billion years without extinguishing? After listening to the explanation of the scientist, I understand that the liquid is high.

Human beings have never stopped exploring this universe, and the universe contains too many things, and human beings are really extremely small compared to this. But even if it is small, we will not stop trying to explore.

As we all know, in addition to water, the source of life is also the sun. Basically, all life on earth is inseparable from water, and the sun is the same. Plants need the sun for photosynthesis, and humans can't do without the sun, so it can be said that the sun gives life to all things in the world and illuminates the world.

So when did the sun start appearing, and how long has it been on this earth? The age of the Sun is about 4.6 billion years based on the age of the Earth. So there will be many friends who are curious that the sun is also a luminous body, and it is constantly burning itself, why has it not burned out yet?

Everyone knows that ordinary objects need fuel to burn, and the sun should be no exception! If you run out of fuel, will the sun disappear? Although the sun moves the beams to heat and heat, it does not rely on fuel.

Because if it were this way, the sun would have long ceased to exist.

The sun does not burn with fuel. It's more like a nuclear power plant, with a fusion generator in the middle. According to the theory proposed by Einstein, any object with mass produces an equal amount of energy.

According to the law of conservation of energy, the sun is constantly producing heat and emitting light, but this energy is not constantly depleted. Because it belongs to a process of continuous transformation of energy, energy is always present as long as the mass does not disappear.

And according to some scientists, the more massive these stars are, the shorter their lives will be. And the reason why the life of the Sun can last for such a long time is because the Sun belongs to the yellow dwarf. It should have a lifespan of at least 10 billion years, perhaps longer.

This is also an important reason why the sun can give life to the earth.

The sun is not burning, it is doing nuclear land-sail fusion. Nuclear fusion is a kind of physical change that is common in the universe, and the temperature and pressure in the core area of the sun are very high, and nuclear fusion reactions can only occur under the conditions of high temperature and high pressure.

There is a misunderstanding here, in fact, the sun is not burning, but constantly undergoing nuclear fusion, the main components of the sun are hydrogen and helium, and the high temperature and high pressure conditions inside the sun support the continuous nuclear fusion of the sun, from its birth to the present.

This is because the sun is constantly engaged in nuclear fusion, which is why this happens, and the mass of the sun is also very large.
