It is well known that the earth will be destroyed one day. If the earth is destroyed, human beings should escape from the solar system and find a place most suitable for their survival outside the solar system. So now many scientists are devoted to studying the environment suitable for human survival in outer space.
To prevent great changes in the solar system one day, the earth will go extinct because of the changes in the solar system, but at that time, human beings did not have a home suitable for their own survival, and where human beings should go became a very important issue.
Many people predict that in five billion years, the solar system will undergo major changes, the energy inside the sun will be nearly exhausted, and then the sun will gradually evolve into a huge red giant, and the sun will devour the surrounding planets, and the earth will be no exception.
However, after 5 billion years, human beings may not exist, and life on earth will change every once in a while. It is only1.600 million years since human discovery, and it may take hundreds of millions of years for human beings to evolve into another life.
If in recent years, the end of the world is coming.
The environment of the earth will be destroyed, so the existing scientific and technological level of human beings is not enough to support people on the earth to live on other planets. Suppose the day when the earth is destroyed.
The scientific and technological level of human beings has reached the level that a large number of human beings can shuttle through the universe, so human beings can first move to the fourth largest satellite of Mars or Jupiter, and when they need spacecraft fuel, they can go to Titan to get it, thus completing the successful escape of human beings.
On the premise that human beings can build an aircraft carrier capable of carrying a lot of life on the day when the earth is destroyed, an escape route that is most suitable for human beings is obtained by analyzing the environment of several planets close to the earth.
After the destruction of the earth, before the harsh environment persecuted human beings to death, human beings should gather on aircraft carriers or other large planes early to move. After some humans are placed on Mars, the rest can go to Enceladus.
Enceladus is covered with ice.
At the same time, due to the influence of gravity, Europa is rich in water resources, and humans can convert water resources into oxygen through some devices. When the fuel of a large plane is not enough to support the long-distance travel of the plane, human beings can go to Europa to seek fuel.
Because Europa's surface is covered with methane lake, and methane is the main component of aircraft fuel. With a steady stream of aircraft fuel, humans can plan longer escape routes.
