Twenty-five years and one Nobel prize after the discovery of the first planet around another Sun-like star, we now know of thousands of planets outside our solar system (exoplanets). These systems are typically billions of years old. Over these long lifetimes, gravitational interactions among the planets can lead to violent collisions and restructurings of their orbits. Indeed, the observed sample shows strong evidence of having been sculpted by such cataclysms, but the dynamical pathways to such instabilities, and the prediction of their associated timescales, are long-standing theoretical problems. I will describe how we were able to solve this prediction problem using machine learning techniques, how the clues from this effort have helped us recently illuminate the underlying chaotic dynamics, and how this has opened new doors to understanding the planet formation process.https://bard.zoom.us/j/86163995517
