I wonder if this is related (in a very large scale sense) to the sand pile model and self organized criticality... https://en.wikipedia.org/wiki/Self-organized_criticality https://en.wikipedia.org/wiki/Self-organized_criticality The sand pile model: if one builds a pile of sand, dropping onto it a small number of grains at a time, individual grains will slide down the slope - but there's a critical angle at which any additional grains can trigger a catastrophic avalanche. https://nautil.us/the-math-of-the-amazing-sandpile-238320/ https://nautil.us/the-math-of-the-amazing-sandpile-238320/
