3-Body Problem

The three-body problem involves predicting the motion of three celestial bodies, like stars or planets, interacting through gravity. Unlike two objects, which follow predictable paths, adding a third creates complex, often chaotic motion that can’t be precisely calculated with simple formulas. Small changes in initial positions or velocities can lead to vastly different trajectories over time. This problem highlights the difficulty of solving certain gravitational systems directly and has important implications in astronomy and physics, illustrating the intricate and unpredictable nature of multi-body gravitational interactions in space.
