Why can t humans live without the sun? Why don t humans go to the sun?

Hello, human beings are inseparable from the sun, mainly because all creatures on the earth are inseparable from the sun, the sun brings warmth to the earth and brings sunlight, so that plants can carry out photosynthesis.

The main reason why human beings can't do without the sun is because without the sun there would be no plants, without plants there would be no oxygen, and without plants, there would be no food.

Human beings can't do without the sun, that's because people have to breathe, plants produce oxygen through photosynthesis, and you are the growth of plants, the origin of our food. Photosynthesis is also required.

Human beings can't do without the sun, mainly because the Ministry of Manpower also needs light and heat, so of course human beings can't do without the sun, if there is no sun, then there will be no position, and there will be no other animal figures, and dreams will not survive.

Solar radiation is a source of energy on Earth. If there is no solar radiation, the temperature on the earth's surface will be very low, and the temperature will be very low, and there will be no living life on the earth's surface, and human beings will not be able to survive. The so-called "everything grows by the sun", without the sun there would be no everything.

The sun brings light to the earth during the day, allowing people to live in the light. In addition, the sun provides heat to the earth, giving humans and other living things a suitable temperature to survive.

Well, the reason why manpower is said to be inseparable from the sun is because the sun brings light to people, and at the same time, words can bring a lot of energy, so it is inseparable from him.

Human beings need the energy, light and heat of the sun to survive, and the food they need also needs the light and heat of the sun for photosynthesis to provide some necessary food energy for human beings.

Because the sun can bring warmth to human beings, light to human beings, and vitality to plants.

Because people need the light and heat of the sun, if there is no sun, the earth will fall into boundless darkness like Pluto, and there will be no life on the earth, and human beings will not be able to survive.

Sunlight is the source of the growth of all things, and without sunlight there is no life.

It is estimated that the May Day flowers make all things grow, relying on the sun, without the sun, there will be no wind, and it will be all dark nights, and the earth will be all a cold planet, and it will be impossible for human beings to survive anymore.

There are no crops in the field, what do you eat? When the earth reaches more than minus 200 degrees, is it a terrible thing to think about? So humans can't live without the sun at all, right?

Why human beings can't do without the sun, that's for sure, if human beings leave the sun, it's the same as fish leaving water, it's the same reason.

Humans are part of the Earth, and the Earth is part of the solar system.

Even the earth is inseparable from the sun, so how can human beings live without the sun?

The reason why humans do not ascend to the sun:

Reason 1: The Sun is a gaseous planet.

The Sun is not the same as the Earth, which is a rocky celestial body, so humans can stand on top of the Earth. The sun is mostly made up of gas, so people can't really stand on it.

Reason 2: The sun temperature is high.

The sun has been constantly moving and changing, successfully releasing 4 million tons of hydrogen energy every second, because the sun continues to release energy, so the earth has light and heat. The temperature on the surface of the sun is so high that people become ashes before they reach the surface.

Some people may have said whether it is possible to wear a spacesuit.

Block it, but astronauts are not exposed to the universe for a long time, so if people wear spacesuits, the spacesuits have not yet burned, and people can't stand it, it's like taking a sauna.

The reason why the sun shines and heats.

The sun releases light and heat by "burning" hydrogen.

The sun started out as a "nuclear furnace", burning hydrogen and emitting waste helium. In the beginning, the Sun was in a delicate equilibrium, with gravity and nuclear pulling and interacting with each other. But by now, the Sun is a relatively mature star.

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

1. The sun is the origin of human life; The origin of life requires energy, and life also needs energy to sustain and continue. Certain temperature conditions are also necessary for the survival and continuation of organisms, and at a minimum, water must remain in a liquid state. The sun brings us warmth and light, providing us with the necessary energy.

Sunlight can give people heat, improve blood circulation, promote the normal secretion of sweat and sebum, sunlight can kill bacteria, so that the surface of the human body maintains a normal bacterial flora. Photosynthetic organisms are the basis of the food chain. The Earth's energy is directly or indirectly supplied by sunlight.

2. Many geological and meteorological disasters on the earth are related to solar activity. Such as solar wind, sunspots, flares, etc.

3. Nowadays, through scientific and technological equipment, people have expanded the direct or indirect use of solar energy, the simplest is solar water heaters, and then solar power generation, using solar energy to drive vehicles.

What a stake! It is precisely because of the light and heat of the sun that the environmental conditions for the growth of life on earth are formed. The heat of the sun promotes the flow of gases and the circulation of water on the earth's surface, and the light of the sun promotes the geological changes of the earth, the photosynthesis of plants, and the growth of animals.

It used to be both friend and foe, but now it is well water that does not interfere with river water. It used to be a descendant to shoot the sun.

Now you and the sun don't care about anyone, do you? Hehe...

Without it, everything would now be almost extinct.

The sun provides light and warmth to humans.

The first possibility is that there is an upper limit to human technology. No matter how much time you spend, no matter how much you seek development, it's impossible to be like a sci-fi movie. Landing on the sun is beyond the limits of what humans can achieve, so humans can never land on the sun.

The second possibility is that humans could theoretically land on the sun, which would take a long time to prepare technically. However, before humans could make these preparations, due to some special reasons, humanity was collectively extinct, so there was no such thing as a falling sun. The third possibility is that in the future, humans can copy and upload consciousness and send a robot with human consciousness to the sun, which is equivalent to a human landing on the sun.

This robot is very advanced and has a special force field that protects it from temperature and electromagnetic waves, and this may be successful.

It is impossible for humans to land on the sun. There are a handful of people in the world who study outer space and the universe, spaceships, and even a few people who study whether the moon can be inhabited by humans. A few days ago, I also saw reports that the United States is working on plans to build Mars, and that these people have made great contributions to humanity.

Everyone sees the sun every day, but you may not know it yet. The Sun is a huge gaseous planet that accounts for the mass of the solar system. Solar nuclear fusion is going on all the time, and hydrogen fusion turns into ammonia, thus releasing a huge amount of energy.

If the spacecraft is able to mature to a surface temperature of 5500 ° C, the material with the highest melting point is pentacarbonate, but it will melt at 4215 ° C. At the moment, no one can fly to the surface of the sun.

There is another reason, almost all other planets have landing sites, but the Sun does not. The solar plasma is always flowing and cannot land. Even after the spacecraft landed, the density of the sun was still too low.

In addition to the landing problem, there is a lot of solar radiation, such as X-rays and gamma rays. Humans can survive on Earth, in fact, the atmosphere has isolated these rays, but when you are close to the sun, you can't isolate them. When approaching the Sun, the electronics on board the spacecraft should be disturbed and malfunction.

Why can't humans land on the sun? There is no sunlight on the surface of the sun, they are all huge flames, the temperature is extremely high, and they simply have nowhere to stay. Solar fusion burns at temperatures of more than 2 million degrees Celsius, and man-made detectors cannot withstand such high temperatures.

They have melted and turned to ashes before they reach the sun.

Human spacesuits are not suitable for long-term exposure, and may be killed by the heat before the spacesuit begins to burn while the sun continues to release ultra-high heat energy. Also, if you're wearing a spacesuit and flying towards the sun, you'll probably die first from cosmic rays in the vast galaxy space.

No, even if you are Mr. Wu Chengen's copper-headed and iron-brained Monkey King!

It uses tungsten, the metal with the highest melting point.

Is it okay to make a head?

The metal with the highest melting point is tungsten.

The melting point of tungsten filament is as high as 3380

And the boiling point reached an astonishing 5927

The melting point is as high as 3380

The boiling point reached an astonishing 5927

The temperature of the center of the sun is about 15 million, and some students may say that we are not drilling into the sun, we are on the surface of the sun, but the temperature of the surface of the sun is also 5500.

In other words, even if our human body is made of tungsten filament, on the surface of the sun, it will turn into tungsten filament vapor in an instant, or in other words, turn into a wisp of white smoke and float away

What if we invent a garment that can resist this heat? Can't you go to the surface of the sun? For example, the return capsule of the spacecraft rubs violently with the air during landing, and the temperature is particularly high.

The temperature of the spacecraft's return capsule is indeed very high when landing, and we humans do have a "fire jacket" with high temperature resistance and low thermal conductivity to protect the return capsule, but this protection is only when the temperature of the return capsule is about 1000 3000, it can play a role in protecting the return capsule and the astronauts, if the temperature is too high, it can not protect the return capsule!

We humans visit the sun in a spaceship, and before we get close to the sun, the return capsule has already turned into steam, so we are long gone!

Even if we can really invent a material that can withstand 6000 degrees of heat to protect us, we can't go to the sun, because the moment the hatch opens, maybe the spaceship will be burned and melted by the sun, or it will directly turn into steam, and even if we humans go up to the sun, we can only be trapped and die on it, because there is no oxygen, and there can be no food at all!

Some people might say, when the sun turns into a white dwarf, will we be able to reach the sun? Actually, this is not possible, because there may have been no humans before the Sun became a white dwarf!

Not now, never ever.

How can it be. Joke, what materials are resistant to such high temperatures, even if there is resistance, what do you eat, it is better to develop other planets than this.

Human beings cannot live on the sun, because its volume is billions of cubic kilometers, 10,000 times that of the earth, the central celestial body of the solar system. A medium-sized star in the Milky Way. It is 100 million kilometers away from the earth, with a diameter of about 1,392,000 kilometers, and it takes more than 3,500 years to walk from the earth to the sun, even if you take an airplane, it will take more than 20 years.

The average density is gram cubic centimeter, the mass gram, the surface temperature is 5770, and the core temperature is 10,000. From the inside to the outside, they are the solar nuclear reaction zone, the solar troposphere, and the solar atmosphere. Thermonuclear reactions are constantly taking place in its central region, and the energy produced is radiated into space.

One in 2.2 billion of the energy radiates to the earth, becoming the main source of light and heat on the earth. Stars also have their own life histories, from birth, growth, aging, and eventually death. They come in different sizes, colors, and evolutionary journeys.

The star's connection to life is not only manifested in the fact that it provides light and heat. In fact, the heavy atoms that make up planets and living matter were created during the explosions that occurred at the end of the lives of some stars. The sun is an ordinary star.

There is nothing impossible in the world, one day, human beings will go to the sun, the moon has been "conquered" by human beings, and the sun will not be far away

Yes, why not, you retreat 100 years, say the moon, I guess you should.

The madhouse went to the cool air, and now, even China is going to go, don't be too absolute, in a few hundred years, maybe you can go somewhere.

Later, when the sun's energy is used up, it will be the same as an ordinary planet.

Yes, as long as we have enough conditions this will not be delusional.

Is it possible for humans to land on the sun?

Of course you can't go, isn't that going to die?

Everything grows on the sun.

If there is no sun, there are no plants on the earth, including mosses, that need to photosynthesize to be alive and do not produce oxygen. Plants certainly do not have any animals that use plants as a food chain – including humans – and do not produce nitrogen. If there is a certain amount of water, it can only accumulate in the depression and never rise.

The heights are forever dry – no clouds, no rain, no rivers, ......

To put it simply, it is a silent, lifeless and microbiome-free dark planet.
