Chaotic Era

Chaotic Era is a noun in the ‘Remembrance of Earth's Past’ series. During an Chaotic Era, the the sun in the trisolarian world follow no pattern, and it is almost impossible to survive. Civilization can only develop in the mild climate of Stable Eras. Most of the time, the trisolarians must collectively dehydrate and be stored. When a long Stable Eras arrives, they collectively revive through rehydration. Then they proceed to build and produce. Because of the three body problem, the arrival and duration of the Chaotic Era could ever be predicted, therefore the trisolarians decided to occupy earth.
