Einstein's General Relativity field equations leave out the 3 body problem too, and also leaves out all the forces of nature except gravity, and Einstein leaves out what gravity does when things become both very small and very massive. And the equations of Quantum Mechanics leave out gravity and Dark Matter. And every mathematical abstraction known leaves out Dark Energy which makes up about 3/4 of the mass/energy of the universe; nobody has a clue what that's all about, it's the deepest mystery in physics.
