As we all know, 71% of the surface area of the earth is the ocean, while only 29% of the land. From outer space, the earth is a blue planet, a water ball, especially the Pacific Ocean, and almost no land can be seen. It can be seen that the water on the earth’s surface is very large, but the land is below the ocean. If we calculate according to the volume of the earth, the water on the earth’s surface is actually very small.
The diameter of the earth is more than 12700 kilometers, and the average depth of the ocean is only 4000 meters. If all the water on the surface of the earth is gathered into a sphere, the diameter of the sphere is only about 800 kilometers, which is far from the volume of the earth. Therefore, the earth is not really a water ball, but it looks like a water ball on the surface. In fact, there is not much water on the earth.
So is there a real water ball among the countless planets in the universe? The answer is yes. We don’t need to go out of the solar system. Take our solar system for example, there are many planets with a lot of water. In the past, when people explored the planets in the solar system, they only observed the surface of the planets, but they did not find the existence of water, but ignored the situation inside the planets.
With the continuous progress of human science and technology, the exploration of the solar system is also deepening. At the same time, scientists also found that the solar system is actually a planet full of water. There are many water planets, but the liquid water of these water planets does not exist on the surface of the planet, but in the interior of the planet. There is no liquid water on the surface, but there is much more water inside the planet than the earth. Such as mu, muwei, Ganymede, muweimen, haiweiyi, etc.
The water content of these large satellites is more than that of the earth, but there is no trace of liquid water on their surface. They are all ice layers frozen by water and dust. These ice layers are very thick, some of them are hundreds of kilometers thick. Under these thick ice layers, there are oceans at least 100 kilometers deep.
The underground water of Ganymede is 1.5 times that of the earth’s surface. The water of Ganymede, Ganymede, Callisto, Titan and other planets is even ten times more than that of the earth. However, these stars are much smaller than the earth. They are not different from the size of the moon. They are the real water balls. The earth can only be regarded as a pseudo water ball.
Some people may say that there are also oceans inside the earth. There is no scientific explanation for whether this is the case. With the current technology of human beings, we are still unable to detect the situation inside the earth. However, according to some ancient legends, there may be a huge space inside the earth, and there may also be an underground world. We can not rule out the existence of oceans inside the earth.
Water is the source of life. The existence of water means that there may be life. The earth can become a living planet without the help of water. Many planets in the solar system have underground oceans. Does that mean there will be extra terrestrial life? In the past, human beings have been searching for extraterrestrial life, but they have achieved nothing, which may be related to human’s understanding of life and the limitations of detection.
When we search for extraterrestrial life, we always look at the environment on the surface of the planet. If it is too bad, we will judge that it is extremely difficult to give birth to life. However, we ignore the possibility of life inside the planet. If the temperature on the surface of a planet is very low and there is no life, but there is a liquid ocean inside the planet, there is the possibility of life.
In the near future, human beings will send probes to explore the internal oceans of several Jupiter satellites. It is not so easy to enter the internal oceans of these satellites. We need to be able to drill through hundreds of kilometers of frozen layer. With the rapid development of science and technology, we will be able to do that in the future It can go deep into the underground ocean, and it is possible to find extraterrestrial life in the ocean. Whether there is a high level of life can also be detected.
There are so many planets full of water in our solar system, so there will be more planets with liquid water in the whole universe. Some water may exist on the surface of the planet, while others may exist in the interior of the planet. This also provides more ideas for human beings to explore and search for extraterrestrial life, so that human beings will not be limited to looking for extraterrestrial life in some habitable zones in the past Search on a planet with liquid water on its surface.
Water may be a common existence in the universe, and alien life may also be a common existence. It’s not that we think that cosmic life is very rare. The reason why human beings have not found the existence of alien life now is mainly related to the relatively backward human science and technology. One is that we can only explore the situation on the surface of the planet, and we can’t detect the situation inside the planet. The other is that we can’t detect the situation inside the planet Another reason is that we are still unable to go out of the solar system and are limited to exploring within a small solar system.
In the future, when human beings go out of the space system and can reach more distant galaxies, they may find more alien life and contact with alien intelligent civilization. The larger the field of vision, the deeper the understanding of the universe, and the faster the development of civilization. We are looking forward to this day.
