N-body problem

The N-body problem is a classic problem in physics and mathematics that involves predicting the individual motions of a group of celestial bodies that interact with each other through gravitational forces. The "N" in N-body refers to the number of bodies involved. In its most basic form, the N-body problem can be described as follows: 1. **Bodies Interacting via Gravity**: You have "N" point masses (bodies) in space, each exerting a gravitational force on every other body.
