The space time interval $\Delta s$ between two events can never be larger than the coordinate time $\Delta t$ between those events as measured in any inertial reference frame.

Question

Quizplus · Accepted Answer

The space-time interval is a measure of the distance between two events in space-time, while the coordinate time is a measure of the time between those events as measured in a particular inertial reference frame. The space-time interval is always the same for all inertial reference frames, while the coordinate time can vary depending on the reference frame. Therefore, the space-time interval can never be larger than the coordinate time.
