timelike

Example:The timelike interval between the events is positive, indicating that one event could potentially be observed by an observer moving at subluminal velocities.

Definition:A measure of time separation between two events in spacetime, which is positive-definite and thus a valid candidate for a real, measurable time difference according to the theory of relativity.

Example:According to general relativity, the trajectory of a freely falling object follows a timelike path in spacetime.

Definition:A path in spacetime along which a material particle could move according to the laws of physics, signifying that the path represents a time rather than a spatial separation.
