In physics, metastability is a stable state of a dynamical system other than the system's state of least energy.

A ball resting in a hollow on a slope is a simple example of metastability. If the ball is only slightly pushed, it will settle back into its hollow, but a stronger push may start the ball rolling down the slope.


You can have something that’s very fragile but stays for a very long time.

In phase transitions - between gaseous, liquid, and solid forms - there is a thing called a metastable state. The material is already at the right temperature for, say, water to start boiling, but because there is no disturbance to it, it stays in the previous transition. If you then drop a little speck into this kettle of metastable water, it will instantly start boiling.

I think societies when they become stabilised or inactive in this way, they’re in a metastable state. And they can last there for centuries. It’s very similar to a dry forest.
