world line

noun Physics

A curve in space-time joining the positions of a particle throughout its existence.But then we have a problem, because a string oscillates in space and time, and as it oscillates, it sweeps out a two-dimensional surface in spacetime that we call a world sheet (compared with the world line of a particle)....

It does possess conserved quantities, its world line does constitute a causal process, and it is not capable of moving faster than the speed of light.
As in the classical twin paradox, an observer at rest relative to the preferred inertial frame measures the longest proper time between any two events on his or her world line; moving observers always measure less.
