i know you want to see the solar system as something that's fixed and "natural". inalterable. many of the early greeks liked this concept of the universe that they understood. and, it's hobbesian, in some way. but, it's just another type of naturalistic fallacy.

the "natural state" of the universe is one where chaos and randomness is dominant, and small variations in only vaguely understood distant forces could very well wipe us right the fuck out.

we are a small planet suspended in an unimaginably large ocean of unimaginably powerful energy, and we get thrown around by the universe at will, even as we remain anchored in place by our sun - which is itself experiencing massive turbulence.

if you want to understand what is happening in front of you, you need to begin by understanding how small you are.
