Three masses attract each other through Newtonian gravity. Unlike the two-body problem, this system has no general closed-form solution: the motion is chaotic, and tiny changes in the starting positions or velocities lead to completely different futures. The simulation integrates the equations numerically with small sub-steps to stay accurate through close approaches.

Two bodies under gravity are perfectly predictable; three are chaotic. Why the three-body problem has no formula — and what the Netflix show gets right.
