Netflix's show "3 Body Problem" involves a three-star system.NetflixThe three-body problem is a centuries-old physics question that puzzled Isaac Newton.It describes the orbits of three bodies, like planets or stars, trapped in each other's gravity.The problem is unsolvable and led to the development of chaos theory.While Netflix's "3 Body Problem" is a science-fiction show, its name comes from a real math problem that's puzzled scientists since the late 1600s.In physics, the three-body problem refers to the motion of three bodies trapped in each other's gravitational grip — like a three-star system.It might sound simple enough, but once you dig into the mathematics, the orbital paths of each object get complicated very quickly.Two-body vs.
