Why doesn t the sun run out of energy? Can anyone elaborate on that?

The sun shines brightly.

The sun is the only energy source in the entire solar system, all energy life in the solar system is derived from the heat of the sun, the light and heat of the sun are very powerful, at present, human beings have no way to get close to the study, and it is difficult to even get close, there is life on the earth because the distance from the sun is just right, it can produce water, so there can be life.

As long as it is energy, it may be used up one day, but it is very difficult to keep the sun without energy. Personally, I think, but at least we don't have to worry about whether the sun will run out of energy in this life.

Will run out!

The age of the Sun is about 4.6 billion years, and it can continue to burn for about 5 billion years. In the final stages of its existence, the helium in the Sun will be transformed into a heavy element, and the Sun's volume will begin to expand until it engulfs the Earth. After a 100 million year red giant phase, the Sun will suddenly collapse into a white dwarf - the final stage of all star existence.

After a few more trillions of years, it will finally cool down completely.

The evolution of stars is a long process, the sun will be about another 4 billion years, the sun will run out of hydrogen for nuclear fusion, and at the same time start the nuclear fusion of helium nuclei, then the sun will begin to expand, about a billion years later, the sun's periphery will expand beyond the current solar system Mars, when it will swallow up celestial bodies including Mars, of course, the earth is no exception, at this time the sun will be on the verge of death. Subsequently, the Sun will have a gravitational collapse and become a celestial body with a diameter and the size of the Earth, called a white dwarf... At this point, the sun will die.

Solar energy has the advantages of universality, harmlessness, large reserves, and long-term use.

1) Universal: The sun shines on the earth, and there is no geographical limit, whether it is land or sea.

Found everywhere in the mountains and on the islands, it can be exploited and used directly, easy to collect, and free from mining and transportation.

2) Harmless: The development and utilization of solar energy will not pollute the environment, and it is one of the cleanest energy sources.

3) Enormous: The amount of solar radiation reaching the earth's surface every year is equivalent to about 130 trillion tons of coal, which is the largest energy source that can be exploited in the world today.

4) Long-lasting: According to the rate of nuclear energy produced by the sun, it is estimated that the storage of hydrogen is enough to last for tens of billions of years, and the life span of the earth is about billions of years, in this sense, it can be said that the energy of the sun is inexhaustible.

From the energy conservation and emission reduction targets of various countries and the United Nations' "Special Report on Renewable Energy", it can be seen that achieving a high proportion of renewable energy substitution by 2050 is a worldwide trend, which will promote the development of China's solar photovoltaic power generation industry.

By 2030, the entire energy demand will reach 5 billion tons of standard coal, and in 2050 it will reach 5.2 billion tons, renewable energy will account for 40% of the total energy demand in 2050, and the proportion of renewable energy in electricity demand will reach 60%, and the installed capacity of photovoltaic power generation may reach 1 billion kW. The strong support of national policies will promote the rapid and healthy development of China's solar photovoltaic power generation industry.

As for the question of whether the mass of the sun will decrease as it continues to release energy, my personal opinion is that the sun continues to nuclear fusion.

The process of combustion will produce the phenomenon of continuous release of energy, which has the mass of energy matter, and of course it will appear to be less and less inevitable. Why? Because:

The Sun continues the process of nuclear fusion combustion that can be used for the solar system.

The continuous delivery of light, heat and dust particles can provide a steady stream of dust particles for the birth and growth of all things in the solar system. The total matter of the solar system is constant, and the sun is constantly releasing energy, and its volume and mass will become less and less, on the contrary, the matter in the solar system will appear to be more and more, which is an inverse proportional relationship.

Solar mass. The process of gradual reduction will gradually reduce the strength of the solar magnetic field, which will lead to the gradual contraction of the space range of the solar system, which will lead to the eight planets of the solar system.

A natural phenomenon in which celestial bodies gradually move closer to the Sun.

and not a phenomenon far from the sun.

As the sun continues to release energy, the mass becomes less and less so that the fusion combustion process occurs.

The temperature generated will gradually decrease, and the process of the earth gradually getting closer to the sun can keep the earth at a moderate distance, and it has always been in a moderate spatial position in the habitable zone of the solar thermal energy temperature difference, which will make the natural environment on the earth.

It can be kept in a constant state all the time.

Although helium fusion produces less energy than hydrogen fusion, it is also hotter, so the outer layers of the sun will expand and release a portion of the outer atmosphere into space. At the end of the process of turning to new elements, the mass of the Sun will decrease slightly, and the outer layers will extend to the current orbit of the Earth or Mars (at which point the two planets will be farther away from the Sun due to the decrease in the mass of the Sun).

It can be seen that the process of continuous nuclear fusion combustion of the sun will produce the phenomenon of continuous release of energy, and it will have the mass of energy matter, of course, it will appear to be less and less inevitable. In addition, the decreasing mass of the sun will not cause the earth to move away from the sun, on the contrary, the earth will gradually move closer to the sun, and the earth's natural environment can always remain unchanged, and it can adapt to the survival of living things, so please don't worry about this.

No. Because the sun is constantly releasing energy, it does not lose any mass, so its mass does not decrease.

It does not decrease, its energy is continuously generated, and it has nothing to do with its own quality, and there is no phenomenon of increasing one or the other.

In fact, it will not decrease anything, at the moment the sun is still in its youth, and the decrease is too little. In fact, the main combustion in the sun is hydrogen. But scientists have found that there are very few things going on in the sun.

What if the mass of the sun keeps decreasing?

I don't think the sun is eternal, it will change one day, it's just that the time hasn't come yet.

I think his energy will be depleted, because there is nothing he will always be there, and it is impossible to use it without a little wear and tear.

The sun is not eternal, it will gradually die out over time. Its energy will be depleted, and the sun is currently in its prime, with many years to live.

The sun is not eternal. Its energy will be depleted in 4 billion years, and the sun will be extinguished.

The sun is plasma and burns out with too much energy released?

What will be depleted will not exist forever in the vast universe.

The mass of the sun is very large; There are a lot of raw materials; Moreover, the nuclear fusion reaction area is small; At the same time, under the combined action of the sun's gravity and magnetic field, the energy inside the sun is released outward in a relatively stable way. <

According to Newton's law of universal gravitation, we can understand it very clearly. The gravitational force of an object is proportional to its mass, and inversely proportional to the square of the distance between them. <

The sun is carrying out nuclear fusion reactions all the time, and the so-called nuclear fusion reaction is to combine two lighter atomic nuclei to form a relatively heavy nucleus, and in this stage of change, two nuclei will release a part of the mass in the form of energy in the process of forming a nucleus. In the universe, all stars are undergoing this reaction process from beginning to end. Therefore, igniting Jupiter is a simple way of saying that it is to have Jupiter produce a series of nuclear fusion reactions.

In stark contrast, the nuclear fusion reaction in the interior of the sun takes a very long time, and the nuclear fusion reaction in the interior of the sun has been carried out for 4.6 billion years so far, and it will continue to carry out nuclear fusion steadily for 6 billion years in the future, which is really unimaginable. No matter how massive the sun may be in mass or volume, it will eventually burn out, and what will become of the sun one day in the future?

According to some scientific research, we can think of the "tragic" end of the sun, the sun will gradually develop from the current prime of life to the red giant stage, after which the white dwarf will be formed due to the exploration point, and finally the black dwarf composed of c elements, which is the final end of the sun.

Yes, the sun, as a white dwarf in the universe, has a time when it is exhausted, and the solar nuclear fusion reaction is the process of combining lighter atomic nuclei to form a relatively heavy nucleus, and when the nuclear fusion is over, the sun becomes a white dwarf when the solar energy is exhausted.

The sun's energy is not depleted, but the sun does not exist forever. If the universe disappears one day, then our sun will disappear with it, because the sun is part of the universe and is not an independent existence.

The sun's energy will be depleted, and the sun will not exist forever. Unfortunately, when the sun runs out of energy, it will collapse into a black hole, but we don't have to worry because humanity may be extinct by then.

The sun will also run out of energy, how long can the sun "burn"?

The nuclear fusion process, which is carried out inside the sun, which is the nuclear fusion process of hydrogen fusion into helium, constantly releases huge amounts of energy and continuously radiates into space, which is solar energy. This nuclear fusion reaction inside the sun can be sustained for a long time, estimated to be about billions to tens of billions of years, and solar energy can be said to be inexhaustible relative to the survival and evolution of human beings.

The universe is an infinite existence, and even if our earth is placed at the level of the universe, it is just a drop in the bucket, which is not an exaggeration at allThere are countless planets in the universe, and the sun is a very special star to observe, people will ask the sun is constantly releasing energy, so its mass will decrease? In fact, it will not reduce anything, and at present, it is still in the youth stage, and the reduction is too little.

In fact, the main combustion in the sun is hydrogen, but according to the discoveries of scientists, the proportion of hydrogen in the sun is actually very small, so the basic combustion has no effect on the quality, and another point is that because the position of the sun is still very special, there are many substances in this place, so it can be absorbed into its own, so that although the mass of the sun is consumed, it is also replenished in time, so the mass of the sun is actually not consumed, and it belongs to a relatively special existence. The sun actually has a great role, and from a certain point of view, Venus is very similar to the sun, but it can't be the sun.

The sun actually plays a very important role in promoting the development of life on the earth, a very simple example, we need to absorb oxygen into the lungs, but exhale out carbon dioxide, at this time plants will absorb carbon dioxide and convert it into oxygen, so as to achieve a balance of the ecosystem, but the whole process If there is no sunlight, plants will not grow, not to mention whether human beings can survive is a big problem, so the sun is very important for human beings.

And with the continuous development of human beings, especially in the early years, in order to break through, not only indiscriminately chopped, but also directly led to the environmental destruction of the deep forest, many resources have been destroyed, and even regeneration is basically impossible, so at this time people began to want to use some green resources, such as solar energy is a good resource, you can understand.

The sun is the central body of the solar system, and all the planets in the system are under the control of its gravitational pull, and as the sun ages, it will continue to lose mass, and the gravitational force will become smaller and smaller, so what is the effect of such changes on the solar system? Will the scene of the death of the sun in "The Wandering Earth" really come true?

The sun is constantly releasing energy, and its mass will not decrease, because mass and energy are two concepts, and the release of energy has nothing to do with mass.

If, in an ideal state, the sun only needs to release energy, then its mass decreases because energy is directly proportional to mass.

Yes. In reality, the mass of the sun is decreasing, and it is decreasing at the same rate every year.
