A rocket launch. Our nearest stellar neighbor. A Netflix show. All of these things have something in common: They must contend with the "three-body problem." But exactly what is this thorny physics ...

When three massive objects meet in space, they influence each other through gravity in ways that evolve unpredictably. In a word: Chaos. That is the conventional understanding. Now, a researcher has ...

Take a glance at our solar system and beyond, and outer space seems pretty orderly. Our eight planets travel around the Sun with apparent predictability and even the stars themselves appear to march ...

The orbits of a trio of stars can be so chaotic that it’s impossible to precisely calculate the stars’ future trajectories. That’s the real science behind the name of the hit Netflix show, 3 Body ...

New research suggests that a binary pair of Kuiper Belt objects, known as the Altjira system, is actually made up of three separate bodies orbiting one another in a complex triad. This rare orbital ...

The Kuiper Belt object Altjira was thought to be a binary, but closer analysis suggests that it is highly likely to be a triple system This raises the question of the three-body problem; if Altjira ...

The 3-body problem looks simple: three objects, one gravitational system. But it reveals something shocking — even basic gravity can become unpredictable, chaotic, and impossible to solve perfectly.

The three-body problem is a physics conundrum that has boggled scientists since Isaac Newton's day. But what is it, why is it so hard to solve and is the sci-fi series of the same name really possible ...
