critical point
Make-or-break juncture
Critical point names a threshold where conditions change decisively.
In physics and chemistry, it's the specific temperature and pressure at which a substance's liquid and gas phases become indistinguishable.
In mathematics, it's where a function's derivative equals zero or is undefined—peaks, valleys, and inflection points.
More broadly, any situation reaching a critical point has arrived at a moment demanding resolution: The negotiations reached a critical point.
