Ask PrometheusA wall in a parameter's window, beyond which the thing cannot persist even though its parts do.
Point of no return (noun) means: A wall in a parameter's window, beyond which the thing cannot persist even though its parts do. It emerges from window, wall, parameter, persist: The components together establish a threshold in a condition's range where persistence fails despite continuity of parts. In the EmergenceLexicon it sits at computed level 11, chaining down to the four foundations (space, time, energy, pattern).
