    If there is no oxygen in space, why can the sun continue to burn for 5 billion years?

    Because the sun itself is a natural spherical fire body, it does not need oxygen. His inner core is the one that releases his own energy. His burning is not the burning of the earth.

    The central temperature of Yang is as high as 15 million degrees Celsius, and it is an area that integrates high temperature, high pressure, and high density. It is undergoing thermonuclear reactions all the time and releasing energy outward. When this energy reaches the surface of the sun, the temperature drops to 6,000 degrees Celsius, but this temperature is enough to melt all foreign objects.

    It turns out that the burning of the sun is different from the burning we see on Earth, the conditions required for the burning of objects on Earth do not exist in space, and the burning of the sun is also different from the combustion we understand as burning. According to scientists, the sun is not actually burning, it is a process of releasing energy through nuclear fusion.

    Because the sun shines and heats, it cannot be called burning. It is because of the nuclear fusion reaction that takes place inside.

    The sun is not burned by oxygen, but by the fusion reaction inside that causes it to glow and heat.

    The burning of the sun is not the kind of burning on Earth, it is a nuclear fusion reaction inside the sun.

    Therefore, with the current capabilities of human beings, the detection of the sun can only reach the part outside the sun. But what is certain is that the sun's light and heat are consumed at a rate of millions of tons per second, so its energy is not endless.

    The sun doesn't simply burn.

    This burn is not the other.

    1. Combustion in chemistry (which requires oxygen and other accelerants) refers to the intense oxidation reaction of luminescence and heat release.

    This type of combustion definitely requires fuel and accelerants.

    2. The "combustion" of the sun is essentially a thermonuclear reaction, nuclear fusion, not a chemical change is a higher-level change beyond chemical change, in this change, the smaller atoms fuse into larger atoms, releasing huge energy, similar to the principle of hydrogen bomb.

    In many cultures, the sun is one of the first gods that people began to worship because it gives people warmth and light, and even now, some primitive tribes and ethnic minorities worship the sun god.

    On the surface, the sun emits dazzling light and heat, and feels very similar to fire in the senses, so the sun seems to many people to be a large burning ball of fire, and it seems to be far less large than the earth in which it lives.

    But we all know that space is actually a vacuum environment, there is no air at all, so how can the sun burn? In fact, the sun can emit light and release heat, not because it is really burning, and the source of its energy is nuclear fusion, and a large amount of energy is released. And according to the results of modern research, the source of all matter on the earth is actually the sun, and plants and some microorganisms can directly use light energy, synthesize organic matter, and become the energy of other organisms**, so as to achieve a vibrant earth.

    In fact, not only for the earth, but also for the entire solar system, the sun is a very important star, without it, the universe would be dark, and many stars would not be able to orbit in their orbit in an orderly manner as they are now. And the sun only looks smaller because it is too far away from the earth, but in fact it is more than 1.3 million times the size of the earth.

    The researchers found that there is more than 70% hydrogen and 27% helium in the interior of the sun, and the rest is a combination of other elements. About 5 billion years ago, the sun absorbed hydrogen from space, so due to internal and external pressures, nuclear fusion reactions took place, and the sun began to radiate heat outward.

    But the sun does not exist forever and provides heat to the earth forever, because the total amount of energy is certain, and it provides heat and light, and naturally it has to consume something. It is estimated that in another 50 years, the sun will die. Some people may wonder if it is good to be annihilated, at that time, human beings had to obtain energy from ** to trap the source of socks, but in fact, it was unknown whether there were human beings at that time.

    The primordial heat of the sun is due to its internal pressure. According to the principle of the law of gravitation, the greater the mass of an object, the greater its gravitational pull. In the early years of the sun's snowballing, as the mass increased, the gravitational pull became stronger, the more material it attracted around it, the more mass it increased, and so on, the mass of the sun increased.

    At the same time, the greater the mass, the greater the internal pressure, so that the temperature continues to rise. Thermonuclear fusion occurs under sufficient pressure (called critical pressure) and a suitable ignition temperature. As the mass of the original sun continues to increase.

    Increase in internal pressure and temperature.

    After the sedan car is short enough to meet the conditions for a thermonuclear reaction.

    The sun began to shine.

    Become a star. Generally speaking.

    The gas planet is going to become a star.

    There has to be a certain quality.

    In this way, the pressure and temperature inside it can reach the conditions of a thermonuclear reaction.

    This mass is called the critical mass. A typical example is Jupiter, the largest gaseous planet in our solar system, which is also a gaseous planet composed of hydrogen, but because its mass is less than the critical mass, the internal pressure and temperature cannot meet the conditions for thermonuclear fusion, so it can only be a gaseous planet. However, it is a potential sun, and some scientists speculate that after the destruction of the sun in the future, Jupiter, which is not constrained by the sun, will attract the surrounding planets to form a small solar system by virtue of its position as the leader of the solar system, and at the same time continue to absorb the surrounding rubber sail material to increase its mass, and after reaching a critical mass, it will shine and become another sun, but that will be 5 billion years later.

    In fact, the sun does not burn. Department of space, no oxygen point burning?!The atoms of the solar system react with the atoms and release left energy, which has light energy, so there is light transmitted to the earth, and of course, the light system can be sent by the true direct Fu.

    How does the sun, without oxygen, continue to burn for 5 billion years? I'm sure many people know that we can live on Earth now because we only have oxygen to breathe here. We can't survive without oxygen.

    Fire also burns oxygen, for example, matching, lighters and other combustion phenomena occur only with the participation of oxygen. According to this phenomenon, there is such a problem. We feel the sun burning from the sun.

    But the doubt is that there is no oxygen in space, how can the sun last for 500 million years?

    The sun is the hegemon of the solar system. It is an ideal sphere intertwined by a hot plasma and a magnetic field. Its size is very large.

    It is 109 times larger than the Earth in diameter and occupies almost the mass of the entire solar system. All. The sun brings light and heat to the earth, people can survive and reproduce the earth's descendants, and human society can develop so prosperous.

    How about the sun burns out? Will it burn? According to the authority on chemical composition, there are now three seasons of sunlight quality, and almost all that remains, but there are also small amounts of other elements doped in it, such as oxygen, carbon, neon and iron.

    The radius from the center of the sun to the sun is its nuclear reaction zone, from where the sun releases a huge amount of energy.

    The temperature of the solar nuclear reaction zone has reached 15 million degrees, that is, 30 billion atmospheres, carrying violent activity every minute, and thermonuclear reactions take place, that is, four hydrogen gas aggregate deformation and protons. Simply, there will be 6 million tons of hydrogen per second to transfer 100 million tons of helium, and 4 million tons of energy will also be released. The sun burns in the way of nuclear fusion, and it is constantly emitting light and cosmic heat.

    But because the sun is a yellow dwarf, like it is a dramatic burn, it will not continue. Scientists**, the yellow dwarf lived only 10 billion years and now spends more than half of its time in the sun. The data shows that the age of the sun is about 100 million, and then the hydrogen of this yellow dwarf will be depleted in 5 billion years.

    The core will also collapse.

    In most people, it is always believed that the sun can always accompany us from sunrise to sunset. In fact, the sun will disappear. Although people's lives are far below the sun, the children's offspring will be endless.

    The sun can't be pru, only this. Without oxygen in space, how can the sun continue to burn for 5 billion years? Will it be burned?

    If the sun is gone, we can continue to live on what you have created, but this "self-sufficient life will not last long." Because without the sun and heat, the earth will not only fall into eternal darkness, but slowly and slowly fall. Eventually, the Earth will become a frozen world, where the oceans are frozen and living things have died.

    Plants cannot photosynthesize, oxygen will become thinner and thinner, our body will also suffer from severe discomfort, some internal organs will also have problems, and our ** will have no loss of light. We only save that food will run out, a large number of plants will die without light and heat, and ecosystems will collapse.

    Peculiarities of the internal structure of the Sun. The energy in the sun is so abundant that it is hard to imagine, not to mention that the sun is still a star, much larger than the planets in all aspects. So without a long period of consumption, the sun will not burn out at all.

    Because the burning of the sun does not depend on oxygen as a necessary condition. The burning of the sun is caused by the constant fission and fusion of ions on its surface.

  17. Anonymous users2024-01-21

    Because the sun does not need oxygen to spontaneously combust, the sun produces energy through constant motion, allowing heat to flow continuously.
