In the novel " Wandering Earth," the reason why the coalition government did not delay until the helium flash was because they had taken a series of measures to deal with this situation. First, the coalition government adopted the " evacuation measures " to disperse the Earth's residents to various parts of the world to reduce the pressure on densely populated areas. Secondly, the coalition government allocated resources and energy from all over the Earth to ensure sufficient supply to support various activities on Earth. In addition, the coalition government also developed a series of plans and strategies to deal with possible disasters, such as building " thrusters " to accelerate the Earth's movement or conducting " interstellar migration " to transfer Earth's residents to other planets. The coalition government believed that the above measures could minimize the impact of the disaster on Earth's residents and delay the time until the helium flash occurred.
