It's possible for an equilibrium to turn into a non-equilibrium, e.g. for a normal glass of water to fluctuate for no reason and turn to ice. Physicishits said that. But they also said it's so rare that it will never happen on this Earth. But somehow it's still possible?
If it will never happen it is impossible for it to happen simple as.
An equilibrium will never turn into a non-equilibrium, therefore it is impossible for it to happen.
I will never decide to cut my pinky finger off, therefore it is impossible for me to do so.
>b-but what if you change your mind
You do not know me better than I know myself. It is literally literally impossible for me to cut my finger off because I know I will never decide to do it.
