Academician of stellar migration

Wang Jizuo, an academician of the Chinese Academy of Sciences, made a small survey here, and said on Earth Day that the life of the earth is still 4.5 billion years, so there is no need to worry that development will make it dry up soon. Not only that, the earth is like a charging treasure, which can be used as a "power supply" to output geothermal energy, but also as a "battery" to store energy for later use. Geothermal energy can be used for agriculture, power generation and southern heating. Netizen said: "Earth brand" charging treasure will be used for another 4.5 billion years.

The earth is one of the eight planets in our solar system, and from the known situation of mankind, only the earth in the solar system is suitable for human habitation. Although in recent years, scientists have been exploring extraterrestrial objects. However, the "second earth" has never been found. But there is a "second earth" plan, that is, human beings may immigrate to Mars in the future, and then turn Mars into a "second earth" for human beings to cope with the problems that the earth may face in the future. And in 2020, Ouyang Ziyuan, the chief scientist of China's lunar exploration project and academician of China Academy of Sciences, who is known as the "father of Chang 'e", also publicly stated that "it is not impossible to transform Mars".

The entire solar system was formed about 4.6 billion years ago, marked by the formation of the sun. Shortly after the formation of the sun, planets such as the earth also appeared, about 4.5 billion years ago. During these 4.5 billion years, the earth's climate has undergone earth-shaking changes, from extremely harsh environment to today's livable environment. We can find evidence of billions of years ago from the rocks of the earth by means of radioisotope determination, but even after 1 second, it is difficult to see the future, so all statements about the future are guesses.

When the earth was formed, the temperature was very high and it was a fireball. The reason why it didn't become a star is that its mass is not big enough to induce a nuclear fusion reaction. After the formation of the earth, in the following years, the temperature began to drop continuously, forming a solid crust, which covered the earth's surface like a quilt. Under the crust, the mantle and the core were very hot, but due to the existence of the crust, the energy of the mantle and the core was not released quickly, but released very slowly.
