Chaos in the Solar System: Are planetary orbits really unpredictable? The Three-Body Problem.

Описание: In this video, we will explore one of the most famous and complex problems in classical mechanics, which has puzzled scientists for centuries. Is it possible to predict the motion of three bodies interacting gravitationally? The answer turns out to be not as straightforward as it might seem at first glance.

We will delve into the history of this challenge, starting with the works of Newton and Kepler, and examine how it relates to the motion of planets in the Solar System. Together with an expert, we will analyze why planetary orbits are not perfect ellipses, how the mutual influence of celestial bodies complicates the prediction of their motion, and why even the Earth-Moon system is not a simple example of a two-body problem. We will also touch upon the topic of Lagrange points and other intriguing solutions to the three-body problem, and discuss how these solutions can be realized in the Universe.
