A metaphor for any social, political, or intellectual situation so complex that accounting for every relevant actor, force, or variable makes a precise, stable solution impossible. Borrowed from physics (predicting the motion of multiple celestial bodies), it describes a system where every element is both influencing and being influenced by every other element in unpredictable, cascading ways. Attempts to "solve" it with simple models or linear logic fail catastrophically.
Example: Trying to "fix" a polarized online political ecosystem. You have millions of users (bodies), each with their own beliefs, algorithms amplifying conflict, bad-faith actors, media outlets, and real-world events. Any single action (a policy change, a fact-check) sends unpredictable ripples through the entire network, often worsening the problem. It's an N-Body Problem—the interacting forces are too numerous and interdependent for a clean solution.
