Why does the sun shine???????????????

Because the sun is doing nuclear fusion all the time. i.e. hydrogen bomb**. and is accompanied by the release of a large amount of light and heat.

Nuclear fusion, emitting photons, there is light.

Yang is not as simple as burning with oxygen!

See the explanation below:

The sun is a red-hot gas planet that shines on its own. The temperature on its surface is about 6,000 degrees Celsius, and the core temperature is as high as 15 million degrees Celsius. The radius of the Sun is about 696,000 kilometers, which is about 109 times the radius of the Earth.

Its mass is tons, which is about 332,000 times that of the Earth. The average density of the Sun is grams per cubic centimeter, which is about 1 4 of the density of the Earth. The average distance between the Sun and our Earth is about 100 million kilometers.

The structure of the sun is mainly divided from the inside to the outside: the center is the thermonuclear reaction zone, the core is the radiation layer, the radiation layer is the troposphere, and the troposphere is the solar atmosphere outside the troposphere.

According to the theory of nuclear physics, the center of the sun is a thermonuclear reaction zone. The central region of the Sun occupies 1 4 of the entire radius of the Sun and is more than half of the mass of the entire Sun. This indicates that the density of matter in the central region of the Sun is very high.

Up to 160 grams per cubic centimeter. Under the attraction of the sun's own strong gravity, the central region of the sun is in a state of high density, high temperature and high pressure. It is the birthplace of the sun's immense energy.

The energy generated in the central region of the Sun is mainly transmitted in the form of radiation. Beyond the central region of the sun is the radiant layer, which extends from the radius of the sun at the top of the thermonuclear center to the radius of the sun, where the temperature, density, and pressure decrease from the inside out. In terms of volume, the radiant layer accounts for the vast majority of the total volume of the Sun.

Through thermonuclear fusion, the sun emits light by burning large amounts of hydrogen concentrated at its core, consuming an average of 6 million tons of hydrogen per second. After another 5 billion years, the Sun will deplete its hydrogen reserves, and then the nuclear region will shrink and the nuclear reaction will expand to the outside, where its temperature can reach more than 100 million degrees, leading to helium fusion.

Because the sun is a plasma and also a photonic body. Light is a radioactive function of nature. It is also the only function of propagating matter, it can pass through the vacuum, encounter an object, it will be absorbed by the object, accumulate into temperature, the object reaches a certain high temperature, it will also liquefy, the object is also a photon evolution, light metamorphosis into positive and negative electrons, loses the radiation function, is absorbed by atoms, and then converted into atoms, this is the nature of light.

The sun is fusing all the time, and it's burning, but luckily it hasn't fused to iron yet, or we're going to die with the sun. Because the sun is active, it will move when it is alive, and if it moves, it will exert energy outward, and if the energy is too strong, it will shine brightly. Since the problem is a problem of light, I will say light, light is generated because your eyes receive photon information, so let's start from the starting point, because of the high density in the core of the sun, after fusion, energy will be generated, we will just say why the light is emitted, photons at this time basically in the form of gamma rays with radiation to the surface of the sun, of course, the process of this movement can be described as difficult, Because it will collide with the protons inside the sun, just like that, bumping around, randomly gaining energy in Brownian motion, this process takes tens of thousands of years, or even hundreds of thousands of years, to reach the surface of the sun, at this time, the original rays become ultraviolet, X-ray, visible light, etc., and then because at this time the photons propagate to the surroundings in the form of electromagnetic waves, and then you receive the photons, and the information carried by the photons is decoded by your brain, into an image, and it is completed.

So the reason why we can see light is not because the sun is playing this band, but because we chose this band, and if it wasn't this band in the first place, the living thing would also adapt to the corresponding band of the eye. The sun is mainly composed of hydrogen and helium, and the sun uses light nuclear fusion to convert chemical energy into internal energy and release energy outward.

At the beginning of the formation of the sun, there was no light! It also needs to rotate towards the inner core in rotation to condense the core material of extremely high density mass. When the inner core has the ability to interact with an unknown energy field (gravitational wave) in space to produce thermal energy, it is like a high-frequency furnace that melts steel, heating the surface white-hot.

In fact, if the lava inside the earth is not enclosed by the outer crust, the lava inside will also radiate hot light waves into outer space.

Because there are many energy changes that occur on the sun, they are basically nuclear changes, which is why it emits such a strong light.

It is because there are many sunspots inside the sun, and there are many solar storms on it that are constantly moving, so it will emit light.

Because the surface of the sun contains so much luminescent material, the sun produces a unique amount of sunlight.

The sun is not necessarily burning, it is something that glows, it is varied, friction animals plants electric lights and electric rod tubes they all glow, it is possible that it is not burning, burning is polluted, why is the sky still blue sky?

Because the sun is moving, it will move when it is alive, and if it moves, it will exert energy outward, and if the energy is too strong and too strong, it will shine brightly.

It is because of hydrogen fusion that it can emit light. You can release a lot of energy. That's why the sun shines.

Because the composition of the sun itself emits light, and the interior of the sun is constantly in motion, it generates a huge amount of heat and light.

The sun shines because it produces excess energy during the fusion of hydrogen into helium, which is eventually released in the form of light and heat, which is the real reason why the sun shines.

The Sun is a giant nuclear fusion reactor (nuclear fusion is the nuclear reaction of two lighter nuclei to form a heavier nucleus and a very light nucleus or particle. In this process, the nuclear fusion reaction converts the mass of some of the reactants into energy), and the artificial sun mimics the sun's nuclear fusion principle to provide humans with an inexhaustible source of energy.

In terms of technical classification, artificial suns belong to controlled nuclear fusion, and the energy output process of nuclear fusion is artificially controlled to ensure that the early start energy output meets the dynamic demand of human energy.

The quantum effect helps Taishou to open his eyes and search for the sun to burn slowly, which is the secret of the sun's longevity.

The Sun is large, not only in size, but also accounts for 99% of the total mass of the solar system. However, the solar energy burns for so long, not because it ***. Conversely, the greater the mass, the greater the stellar gravitational pull, the more intense the star burns, and the faster the hydrogen depletion inside the star.

As a result, massive stars have very short lifespans, and some of these short-lived stars have a lifespan of less than a million years. However, the mass of the sun is not great in the universe. Scientists estimate that the sun will live for about 10 billion years.

It is estimated that some stars with very small masses can live up to 1 trillion years.

1. The sun is in a gas state of high temperature and high pressure all the time, and under the action of its pressure, a thermonuclear reaction will be produced inside: 4 hydrogen atoms combine to produce 1 helium atom. According to Einstein's formula:

e=mc 2 law, we know the relationship between the mass of matter and energy, so we know that in this nuclear fusion reaction, hydrogen, as the main fuel of the sun, will convert part of the mass into energy, so that the sun will release a large amount of light and heat.

2. The structure of the sun is divided into nuclear reaction area, radiation area, and convection area from the inside to the outside, the sun will first produce energy in the nuclear reaction area, and transmit it outward in the form of X-rays and Y-rays to reach the radiation area, and the radiation area will absorb radiation and then emit radiation, and then reach the convection area, and radiate to us through the photosphere, so that we receive light and heat.

Introduction: The sun will emit light, mainly because the main component of the sun is hydrogen, in which hydrogen nuclei will interact, combine into helium nuclei and release light and heat at the same time, which is also called thermal energy reaction. In this reaction, a part of the mass will be converted into energy to release a large amount of heat, and any reaction inside the sun is similar to an atomic bomb on the ground**, when the process of continuous occurrence in the core of the sun**, it will provide radiation to the sun, allowing the sun to emit light and heat.

The atomic fuel in the sun is extremely abundant, everything on the sun will turn into gas, although the moon also has light, but the moon does not shine, the moon only reflects the sun's light.

When you see the sun, you will feel very warm, because the sun is a star, and there is a violent nuclear fusion inside the sun to glow, but the sun itself has no temperature, and the main reason why the sun is warm is because the sun shines on the object to produce heat, so that humans feel warm. When the light is absorbed by the atoms, the atoms can vibrate more violently, under normal circumstances, the photons and the atoms will not intersect, there will be no heated matter, only when the photons are reflected by the matter, people will feel this, it mainly depends on the frequency of the light and the nature of the atoms.

The sun has a lot of influence on the earth, there are pros and cons, the sun provides the most important power for the earth's water, atmospheric movement and biological activities, and it is also the most important energy on the earth**, the sun will also form an ozone layer on the earth's surface to protect the safety of living things, for human society, the sun will form an ionosphere in the atmosphere, making modern communication possible, and to allow the formation of energy sources such as wind, coal, oil, etc., but too much ultraviolet light will also bring some impact to the earth.

Finally, the light and heat of the sun irradiating the earth have created many conditions for the birth of life on the earth, and it is also a completely pollution-free natural person.

Because the sun is a plasma and also a photonic body. Light is a radioactive function of nature. It is also the only function of propagating matter, it can pass through the vacuum, encounter an object, it will be absorbed by the object, accumulate into temperature, the object reaches a certain high temperature, it will also liquefy, the object is also the evolution of photons, the light metamorphosis into the emptiness of positron and negative electrons, loses the radiation function, is absorbed by the atom, and then converted into the atom, this is the nature of light.

The main reason is that the sun burns all the time, and there is also nuclear fusion, so this happens.

It's because the surface of the sun burns all the time, and it emits light during the burning process.
