Venus talks about immigration.

Humans have lived on the earth for tens of millions of years, from eating animals and drinking blood to digging wells for fire, from the industrial age to the information age. Human civilization has been accumulating and overlapping, giving off new vitality, and the level of space technology has also developed from looking up at the stars at the beginning to close contact with other planets.

We are constantly thinking about whether there will be other life in outer space and constantly trying to touch the dream of emigrating to outer space. If one day, the earth is no longer suitable for human survival, should we be forced to move away from the earth to find another home or wait for destruction or miracle? What should all mankind do?

In fact, as early as 60 years ago, Soviet scientists thought about it. They studied the feasibility of human migration to Venus through the Mars landing program, and boldly asserted that Venus would become the second Earth.

Venus has many conditions very similar to the earth, and it is closer to the earth than other planets, so Soviet scientists think that we can solve some problems through scientific and technological means, and then immigrate to Venus, making Venus a "second earth."

Moreover, Soviet scientists also believe that emigrating to Venus has five advantages: First, the conditions of Venus are similar to those of the Earth. First of all, Venus has a radius of 6,073 kilometers, which is only 300 kilometers smaller than radius of the earth, so its volume is not much different from that of the Earth. In the past, human immigrants did not have to worry about being unable to live.

Secondly, there is gravity on Venus, and everything such as human beings, buildings, daily necessities and water resources will not be thrown out by the operation of Venus and will not adapt to the weightless environment.

Second, Venus is rich in resources. Venus is rich in mineral resources because it has been formed for a long time and its geological structure is similar to that of the earth. If humans immigrate to Venus, resources such as fuel and metal will be guaranteed.

Third, Venus can re-establish the magnetic field. The scientific community generally believes that the reason why the earth can have a magnetic field is that iron and nickel elements in the earth's core become ions at high temperature.

So when the earth rotates, it will generate a magnetic field like a generator. Venus has not been completely cooled inside, and the magnetic field can be re-established during the implementation of the human migration plan.

Venus is closer to the earth. Venus, as one of the eight planets in the universe, is only 40.5 million kilometers away from the earth and is the closest planet to the earth. If humans successfully immigrate to Venus, the time and other costs required to travel to and from the Earth will be much less than those of other planets.

Five, Venus is not easy to hit a meteorite. Since Venus is farther away from the asteroid belt than the position of the Earth, meteorites from outer space will not hit Venus as frequently as they hit the Earth.

If humans immigrate to Venus, it will save a lot of trouble and reduce the chance of accidental damage to the living environment. The advantages put forward by Soviet scientists after exploring Venus make people feel that emigrating to Venus is not a dream.

But why do some people overturn this statement and say that Venus is not uninhabitable, but that we are 3 billion years late?

Venus is actually a veritable "Mars", because it is now like a high-temperature fireball, and the surface temperature is even around 500. Because the environment of Venus is so bad now, many countries have given up their plans to land on Venus and turned to the moon or Mars.

However, before a thorough understanding of Mars, people are still full of expectations for this planet, which is the closest and most similar to the Earth. The Soviet Union made a lot of preparations for emigrating to Venus, and failed and frustrated again and again.

Although we failed to reach Venus and realize the dream of emigration, human beings have obtained a lot of data about Venus through repeated attempts. Soviet scientists found that about 3 billion years ago, Venus still had a lot of liquid water.

Therefore, they speculated that the environment at that time might be similar to the present earth. If humans were born 3 billion years earlier, they might be able to live on Venus. So what was Venus like at that time?

According to relevant information, NASA scientists Michael Wei and Anthony Del Genio calculated the evolution of Venus and imagined what Venus looked like 3 billion years ago.

In the early days of Venus' birth, there were thick clouds over Venus to protect it from wind and rain. Under the protection of clouds, Venus does not need to directly absorb the strong light and heat of the sun, and all kinds of complex rays and radiation in the universe are also "shut out".

Therefore, after being sheltered, Venus condenses into liquid water at a lower temperature, so Venus can "develop" slowly in a "comfortable cradle" and gradually become a planet suitable for life.

But then, the volcano on Venus suddenly erupted on a large scale, and almost all the land on Venus was covered with magma, and the overwhelming hot magma swallowed up almost all life.

Then, the volcanic eruption caused too much carbon dioxide to be discharged into the atmosphere, so the greenhouse effect was more obviously fed back to Venus. Under the vicious circle, Venus becomes a high-temperature fireball.

Some people say that this speculation is too wild, but compared with the experience of the earth, Venus may have a similar situation. Scientists have made a geological analysis of the earth and concluded that the earth has experienced many mass extinctions.

Moreover, there have been times when magma emerged because of the movement of geological plates, so there has been a large-scale extinction of organisms, so Venus may have the same experience. It's just that there are more and more volcanoes on Venus, and the scale of volcanic eruption is bigger, so the consequences are more serious.

But before the two scientists publicly speculated, everyone thought that Venus was too close to the sun, and it was likely to be extremely dry like a melting pot. It was impossible for liquid water to appear, let alone life.

A long time ago, mankind invested a lot of manpower and financial resources to immigrate to Venus. Even now, there are probes left by the Soviet Union on the surface of Venus.

During the Cold War, the United States and the Soviet Union, as two superpowers in the world, competed with each other in various industries and both wanted to convince each other through leading scientific and technological means.

In the space field, the Soviet Union successfully launched an artificial satellite for the first time and boldly launched the Mars exploration program, because with the data at that time, it was very likely that human beings would emigrate to Mars.

After 196 1 year, the Soviet Union launched 28 probes to Venus, but none of them achieved the expected results because of the underdeveloped technology at that time. Among them, the Venus-1 probe did not even reach the atmosphere of Venus, and its whereabouts were unknown.

Although Venus III successfully reached the surface of Venus, it lost communication after landing. But Venus 7 successfully landed on the surface of Venus, which greatly encouraged the confidence of Soviet scientists.

After that, Soviet scientists continued to develop new technologies, optimize the performance of detectors, and launched detectors to Venus many times. The efforts of Soviet scientists were not in vain, and more than 20 subsequent detectors fed back a lot of information to the earth.

The most worrying piece of information is that the atmospheric pressure of Venus is dozens of times that of the earth, and human beings feel like they are on the bottom of the sea at 1000 meters. Even so, the obsession of Soviet scientists landing on Venus has not been shattered.

They speed up the research of detectors and landers, and strive to let humans board Venus and see what Venus looks like with their own eyes. Unfortunately, the environment for exploring Venus was so bad that the Soviet Union had to give up its plan to land on Venus. So what is the real situation of Venus?

It is extreme for human beings to assert that Venus is not suitable for human survival and give up landing. The first is extreme high temperature. Venus's atmosphere is 96% carbon dioxide, so the greenhouse effect is magnified a hundred times.

Venus's atmosphere and surface are like a huge steamer, which constantly accumulates and compresses the heat brought by the sun, so its surface temperature can reach about 500, and most metals will melt.

Even lead with a very high melting point will melt, which is one of the reasons why the detector has failed many times. Followed by extreme weather. Mars also has an atmosphere, but its atmosphere is rich in elements such as sulfuric acid, hydrochloric acid and hydrofluoric acid.

Occasionally, a little low-concentration sulfuric acid rain on the earth will bring a lot of trouble to human beings because of environmental pollution. The atmosphere of Mars is rich in acidic substances and its climate is unstable. Once it rains, it is high-concentration acid rain, and life is difficult to survive.

And the atmospheric pressure mentioned earlier. The atmospheric pressure of Venus is 92 times that of the earth, and the atmospheric pressure on the surface of Venus is equivalent to the atmospheric pressure on the seabed of 1000 meters on the earth.

Invisible pressure from all directions will make you completely breathless. In such a high-pressure environment, it is undoubtedly an idiotic dream for human beings to walk on Venus. Many people are disappointed. Venus has been exploring for decades, but finally it comes to the conclusion that human beings cannot immigrate.

But scientific exploration is endless, and the dream of human beings moving to outer space has never stopped. Through a lot of scientific research, scientists have put forward a new immigration plan, and human beings may be able to successfully immigrate to outer space one day.

At present, the earth's resources are exhausted day by day. If human beings want to survive on the earth, they have to consider the resources and environment problems thousands of years later. If human beings move to outer space, it can alleviate the pressure of resource consumption on the earth and extend the time for future generations to reproduce and survive.

Therefore, many people think that human beings must explore the technical means of moving into outer space and strive to achieve this goal. As early as 20 1 1 year, NASA publicly stated:

Through the space telescope, they observed more than 65,438+0,000 planets, including Kepler -22b, Mars and Titan, on which humans can live. So now human beings want to emigrate to outer space mainly by solving technical problems.

For example, the raw materials for manufacturing spacecraft may need to be obtained from other planets, and solar energy can be used as the main power of the spacecraft to ensure a longer operating cycle of the spacecraft.

The structure of human body is complex, but life is fragile, so it is necessary to predict the disease factors of living in outer space in advance. For example, human beings are in weightlessness in outer space. If they don't exercise for a long time, their muscles will atrophy like patients who have been paralyzed for many years.

Moreover, in the early days of landing in outer space, it is difficult for human beings to adapt to weightlessness, and there will be symptoms such as nausea and vomiting like motion sickness. The most critical technical difficulty is actually to create an environment suitable for human survival.

Even if there are habitable planets in the universe, it will never be more suitable for human survival than the earth. If human beings want to immigrate to the past, they definitely need to transform the planet in advance.

We can't start until it has the conditions for human survival. Scientists are still working hard to study and overcome the key problems in this field, and I believe there will be more good news in the near future.

Humans have been exploring outer space for more than half a century, but they have never found a second planet that is completely suitable for human survival. We are trying to find a new home in the vast universe, hoping that human life can continue.

However, at the present level of science and technology, the hope that we can emigrate to outer space in our lifetime is very slim. If you really want life to continue, please take good care of the only earth, start from small things, start from yourself, and let our home not be destroyed prematurely.
