The "Three-Body Problem" is a classical physics problem that involves predicting the motion of three celestial bodies interacting with each other through gravity. It is a complex issue because the gravitational forces between the bodies create a chaotic system, making precise predictions difficult. This problem has significant implications in fields like astronomy and space exploration. In mathematics, the "Three-Body Problem" has been studied for centuries, leading to various solutions and approximations. Notable figures in this field include Isaac Newton, who laid the groundwork for gravitational theory, and Henri Poincaré, who contributed to understanding chaotic systems.
