1. Planets orbiting the sun: Little disturbances will still result in an elliptic orbit, you need a big disturbance to get the earth fall into the sun or have enough kinetic energy to escape the solar system on a hyperbolic (or in the edge case parabolic) curve. 2. People don’t walk naked through streets, because when you try it, you get punished for it. (and other psychology reasons) 3. Your neurons firing in stable similar patterns that make you able to walk upright instead of falling over. Even if you stumble you can often catch yourself because your neurons fire in patterns that are optimized for you standing/walking.
Bonus exercise:
(The factors I can ignore are basically named above.) Changing the equilibrium: 1. Another star flying through our solar system. 2. Ok “not naked” arguably isn’t a that special case out of the possibility space, so it doesn’t buy you that much to describe it as equilibrium. There are still many possibilities of how you can be not naked. Still, it is quite non-trivial to get into the “walk naked on the streets” state and you’d probably need an intelligent actor who really wants to achieve that. 3. Being pushed hard. Getting signals from other brain areas that you should sit or lie down.
(I may have pruned slightly too much)
