There are eight planets in the solar system, and the earth is the only planet with intelligent life. The universe is vast. Although there are numerous earth like planets, it is believed that the number of living planets like the earth is still very small. If a planet wants to become a living planet like the earth, it needs to meet many conditions, such as being in the habitable zone of a star, having a magnetic field, a thick atmosphere, and being safe and stable enough in the galaxy.
The earth is to meet a lot of superior conditions, so there is the birth of life, the birth of human beings. One of the important external conditions for a planet to become a living planet is to be in the habitable zone. Among the eight planets in the solar system, in addition to the earth, there are two other planets in the habitable zone. They are Venus and Mars, both neighbors of the earth.
I believe many people know that Venus and Mars have not found any life at present, especially Venus. Although it is called sister planet, it is already a purgatory planet and no longer suitable for living. Venus has an average temperature of 462 ° C, and sulfuric acid clouds cover the rocks. The reason why it began to have such a bad environment is that the planet’s carbon dioxide content reaches an amazing 96%, while the earth’s carbon dioxide content is only 0.04%.
Maybe many people don’t understand why there is such a big gap between Venus and the earth, which are also in the habitable zone? What exactly caused Venus to be like this? According to the latest research of scientists, Venus may have been the home of the ocean just like Mars billions of years ago. Like the earth, it is also a beautiful blue planet. It is possible that life still existed on Venus at that time.
In fact, if we find that Venus has a thick atmosphere, we will understand that the ecological environment of Venus long ago may not be worse than that of the earth, and the concentration of carbon dioxide on Venus is so high that it may not be natural. It is the result of unknown changes and long-term accumulation. So what is the reason for the drastic change of Venus ？
A new study by scientists has found that the fact that Venus has become what it is now may be related to the drag of tides, which slows down the rotation speed of Venus and gradually turns it into a dead world as we know it now. According to a new study by NASA, Bangor University and University of Washington scientists, the ocean itself is the culprit. Due to the friction between the ocean current and the bottom of the sea, ocean tides began to slow down the rotation speed of the planet.
Part of the reason for this is the extremely slow rotation speed of Venus – one day on Venus is equivalent to 243 days on earth. This means that any point on Venus will be exposed to the sun for several months. This study shows how important tides are to reshape a planet’s rotation, even if the ocean is only a few hundred million years old, and how crucial tides are to make a planet habitable.
Of course, this is just a guess made by scientists that Venus has become what it is now. Some of it may be normal, but it may not be the whole reason why Venus has become what it is now. The high concentration of carbon dioxide in the atmosphere of Venus is very rare. Some people think that this situation may not be formed naturally. What’s the reason? Scientists need to explore Venus more in the future.
Scientists mentioned the importance of tidal force to a living planet, and the earth can have such perfect tidal force. We should thank the moon. Although the moon is a natural satellite of the earth, its size is too large, and the proportion of such satellites and planets is extremely rare in the universe. At least scientists have not found such a moon in the universe What’s going on.
The individual size of the moon is too large, but it is conducive to the perfect operation of the earth’s tidal force, which is very important for the ecological construction of a planet. It can be seen that it may not be a complete coincidence that the earth can become a planet of life and civilization, but there may be more unknown and mysterious reasons behind it.
For human beings who have gone out of the earth to explore the universe, although Venus is a purgatory planet, and the environment above is too bad to survive, it does not represent the possibility that Venus will become a planet for human beings to live on in the future. Venus is very similar to the earth in size, mass and geological structure, otherwise it would not be called a sister planet.
In addition to so many similarities, Venus also has an important prerequisite, that is, a thick atmosphere, which is very important for human survival. Although Mars is highly expected by scientists to become the second earth of human beings in the future, Mars has a very big weakness, that is, the atmosphere is too thin. If human beings live on it, without the protection of a thick atmosphere, it is difficult to live safely on it.
Of course, the transformation of Venus is far more difficult than that of Mars. If we want Venus to become a habitable planet for human beings, we must solve the problem of carbon dioxide concentration on it. As long as we can reduce the carbon dioxide in Venus’ atmosphere by means of science and technology to reach the range required by human beings, then the average temperature of Venus will also drop significantly, and Venus is likely to become a habitable planet.
The power of science and technology is infinite. Now we can’t transform a planet into a livable planet, but it doesn’t mean we can’t do it in the future. It’s possible that in the near future, it’s not difficult to transform the planet. At that time, the solar system will not only have Venus and Firestar, but also other planets will be transformed by human beings New habitable planet.
