Conditions for human migration to other planets
In addition to oil and coal mines, humans have discovered many other energy sources, such as solar energy, wind energy, hydropower and nuclear energy. But we all know that energy obeys the law of conservation. As we said just now, the formation of oil and coal mines is due to the direct sunlight of trees and animals for millions of years in ancient times. If we lay a large area of solar panels on the ground, then the land under the panels can't regenerate oil and coal mines. The utilization of wind energy and water energy, now there is evidence that it will affect the downstream ecosystem and climate phenomenon. Even though it is known as the cleanest energy source at present, nuclear energy needs to face the restrictions on the exploitation of nuclear raw materials and the control of nuclear pollution.
As a result, the earth's energy problem seems to be in an infinite loop? Although the answer is cruel, there is actually. Many people have questions. Didn't you say that energy follows the law of conservation? So where did all the energy we used go? Children with such doubts might as well ask themselves a question: Do you think it is getting warmer and warmer every winter? 70% of the power plants in the world are coal-fired power plants, and their efficiency is the same as that of traditional internal combustion engines, not exceeding 20%. In other words, the remaining 80% will become heat and be transferred to the air. So in the face of such a situation, the only way for human civilization to continue is to move to other planets.
Moving to other planets requires two considerations. The first is how to complete the process of human migration. Scientists have been studying rockets with faster launch speed and higher load. In fact, if only to launch space experimental equipment and various global satellites, rockets decades ago would be enough. Even though rockets are very advanced now, there is still a long way to go to realize human space immigration. As early as the last century, Europe began to build the first space station, and it has been in orbit for a long time. The development of space station can recycle the spacecraft of space immigrants and improve the efficiency of space immigrants.
Secondly, we need to think about how to start a new life when human beings arrive at the target planet. According to the latest discovery, even the most similar planet in the universe, the environment is not completely consistent with the earth. Therefore, it still takes a long time for human beings to adapt to landing. Therefore, the development of artificial intelligence and robots can help us to build a new city quickly.
