👉 Untransientness is a concept in physics and engineering that describes the behavior of an object or system over time, without any discernible transition or change. It refers to the fact that a physical phenomenon remains unchanged for an extended period of time after it has been observed, measured, or otherwise recorded. In simpler terms, untransient means that the effects of past events are not immediately evident upon observation or measurement. This is often seen in phenomena like the behavior of a pendulum over long periods
