A new study from Trani and his team suggests that the three-body problem is not as chaotic as it is believed, and in fact, follows some regular patterns. The researchers refer to these patterns as the isles of regularity.

However, when three objects interact in space, it leads to complex and often unpredictable paths, making it challenging to determine their future positions. This phenomenon is called the three-body problem .

“Our millions of simulations demonstrate that there are gaps in this chaos—’isles of regularity’—which directly depend on how the three objects are positioned relative to each other when they meet, as well as their speed and angle of approach,” Trani added.To understand the three-body problem in detail, Trani developed Tsunami, a software that runs simulations of three-body interaction in space.

For instance, the study authors noticed that “the object that is eventually ejected from the system after the encounter. In most cases, this is the object with the lowest mass.” However, a completely chaotic phenomenon shouldn’t lead to such uniform outcomes.
