Human beings escape from the earth, which is an ideal that is extremely difficult to achieve but has to be realized. Whether it is the deterioration of the environment, the increase in population density, or the depletion of resources, it is the driving force that drives humans to escape from the earth and seek a second home.
For humans, the two most difficult points to immigrate to aliens are: one is to find a suitable planet, and the other is to be close to each other.
And the planet closest to us is Venus. The radius of Venus is 6051.8 kilometers, which is 94.9% of the earth and its mass is 4.869×10²⁴kg, which is 81.6% of the earth. The surface gravity is 89.6 of the earth, which is far more similar to the earth than Mars.
So, the question is: Since speed is the biggest problem limiting human exploration of the universe, Venus is closer to Earth than Mars, why does no one want to immigrate to Venus, but they all have to go to Mars?
It turns out that Venus is not suitable for human habitation because its surface environment is too harsh.
is not the real surface of Venus, because it is impossible to see the sky there.
The atmosphere on the surface of Venus is extremely dense, 92 times the pressure of the earth's atmosphere, which is about equal to the pressure of the ocean deep 1,000 meters. If a normal person gets there, he will be crushed to death.
In fact, if a person reaches the stage and is not suppressed to death, there will be various other factors that will make him die early.
The atmosphere of Venus is not only dense, but 96.5% of them are carbon dioxide . I don’t need to introduce how terrible the greenhouse effect is caused by carbon dioxide. Such an outrageous carbon dioxide content makes Venus hotter than Mercury, which is closer to the sun than itself, and becomes the hottest celestial body in the solar system besides the sun.
The highest temperature on the surface of Venus can even reach 500℃! Due to the uniqueness of Venus' atmosphere, its minimum temperature is even 467℃, and even metal lead will melt here!
In such a terrifying atmosphere, even the clouds become very terrifying. There is a large amount of sulfur dioxide in the clouds of Venus. It reacts with the oxygen atom separated from carbon dioxide, and adds water vapor to it, and it turns into sulfuric acid. Therefore, acid rain has become the most common weather phenomenon on the surface of Venus.
However, in such a harsh environment, even acid rain cannot be handled.
Scientists said: Before the acid rain above Venus could fall to the ground, it would evaporate directly in the air and return to the clouds because it was too hot. So if a person is lucky enough to reach the surface of Venus, he will at most be killed by heat or crushed by the atmosphere, and will not be burned to death by acid rain.
Oh, right, you may be struck to death by lightning.
The lightning activity on the surface of Venus is extremely frequent, and its intensity is far greater than that of the Earth. According to scientists' observation records, the longest lightning flash on Venus actually lasted for a full 15 minutes!
Someone may ask: If we adjust the atmosphere on the surface of Venus and adjust the air composition to the level of the earth, will it be livable?
Not to mention whether we have such a technology, scientists said: Even if it is achieved, the temperature on the surface of Venus will drop by about 400℃, which means that there will still be a temperature between 64-100℃, which is still difficult for humans to survive.
Although Venus's surface is so harsh, scientists say: This does not mean that there are no creatures on Venus. There may be some creatures with extremely strong vitality above the Venus atmosphere . If there are organisms that can use energy such as ultraviolet rays as food sources, perhaps they can survive over Venus’ atmosphere.
It seems that Mars is better. After all, I can’t stand 40℃, let alone 400℃. Instead of being scalded to death on Venus, it is better to freeze to death on Mars...
