Astrophysics & AI with Python: Unlocking the Secrets of N-Body Simulations with Rebound (opens in new tab)

The universe is a relentless clockwork governed by a single, ubiquitous force: gravity. From the tight dance of binary stars to the majestic spiral arms of galaxies, all motion is dictated by the pairwise gravitational attraction between massive bodies. While the principles of Newtonian mechanics are elegantly simple, the computational task of modeling the motion of many interacting objects—known as the N-Body Problem—rapidly escalates from a solvable physics equation to a profound mathematic...
