The famously chaotic three-body problem, which describes how three masses gravitationally interact, has puzzled physicists for centuries. Now, new research suggests it's not quite as chaotic as scientists thought — and that finding could make the problem more puzzling than ever.
The gravitational interactions between two bodies can be reliably described and mapped using equations. But when you add in a third object, things get wild — the motions of the bodies are unpredictable and often end with one of the bodies being flung out of the system. Even small changes in their starting masses, velocities or positions often lead to drastically different outcomes.
Their experiments began with a binary — two objects orbiting each other — and a single object approaching from elsewhere in space. Across more than a million simulations, the team altered the positions of the two bodies in the binary and the angle at which the single object approached. Then, they let the three bodies interact until one was eventually kicked out of the system.
