The cunning rabbit still has three burrows, but the only place for human survival is the earth. In 2048, the earth's climate officially entered the stage of irreversible warming, and humans had to accelerate their exploration of the path to continuation of civilization. It is too difficult to move the earth to other galaxies, and it cannot solve the problem of "single point of failure". We can only expand the radius of human activities through the development of aerospace technology within a limited time, and at the same time extend the life cycle with the help of the development of biotechnology and intelligent technology. Seeking the continuation of civilization in the vast universe has become the highest goal of the whole. Under this, each individual must make his own choice.
It doesn't seem very kind of me not to like it myself.
