yes

the three-body problem of "gravity" is literally what gave rise to chaos theory.
There is no stable ~orbital~ solution to gravitational systems of three or model bodies. Either they will have eternally chaotic orbits, or they will eject a body, or smash into eachother.

The solar system can aproximate every planet as a two-body problem around the sun.
But when you actually model the solar system as a 8-body-problem, the system is chaotic, and should not have more than a few thousand cycles before ejecting a planet, or smashing planets into eachother.
Basically the entire theory of gravity is an enormous fraud.
