Unfolding Time Through Light

What if you were able to see time - not just a passing moment,  but the path an object or person takes through many moments,  traced through light? In this photo,  I left my camera on a tripod for 30 seconds and tried to sit centered in my camera's view. Then after 15 seconds,  I bolted around to the other side of a barred gate and waved two light sticks in an arbitrary motion,  not constraining myself to any patterns or set rules. In the end I was able to capture my movement over a 30-second period of time,  with the blue and purple streaks of light highlighting the position of the light in the exact moment in which the camera captured them. The same phenomenon could be explained in physics,  especially through world lines. A world line is a topic that mainly exists in Einstein's theory of Special Relativity which is primarily explained as a record of an object's or being's position as it moves through spacetime. In this instance,  the camera was able to capture my silhouette's world line for 15 seconds of completely motionless while also encapsulating the jagged movements of the light behind my silhouette. While world lines typically are a 4-dimensional concept,  the use of long exposure allows for the projection of multidimensional world lines into a 2-dimensional photograph.
