How do I draw a world line space-time diagram with a trajectory of zero proper time?

Posted on May 30, 2010 by admin

I have to draw world line space-time diagram with the observer at the origin of the coordinates. How does a trajectory with zero proper time look like?

A light pulse to the front is a line at 45° up and to the right; a light pulse to the rear is 45° down and to the right. I believe a trajectory of zero proper time is a vertical line; that would represent events which occur simultaneously in different locations.
