three-body-problem

Part II: Three Body delves into the complex scientific and philosophical challenges posed by the titular three-body problem, intertwining historical and contemporary narratives. It introduces key characters such as Ye Wenjie and Da Shi, explores the enigmatic virtual game 'Three Body' that simulates the chaotic tri-solar system, and reveals the Red Coast Base's secretive scientific endeavors. The chapter bridges advanced physics concepts with human and extraterrestrial interactions, setting the stage for the unfolding cosmic conflict.

In this chapter, the travelers experience the paradox of motionlessness despite traveling at immense speed through space, illustrating the principle of inertia. Michel Ardan humorously introduces a cock's crow to awaken his companions, leading to a discussion where Barbicane explains the algebraic calculation of the projectile's initiatory speed needed to reach the moon. The chapter culminates in the realization that the actual speed of the projectile is insufficient to reach the neutral point between Earth and Moon, implying a potential failure of their mission.
