Such floor plans are the descendents of the mathematical work of a 17 th century artillery officer cum scientist and philosopher. His name was Rene Descartes and he created the x, y and z-axes system we know as Cartesian coordinates.
Cartesian coordinates tell where something is.
They say nothing about when it will be there. Time complicates matters. Einstein proved that time depends upon who is watching it and from where they do their watching. Two observers may comprehend time quite differently. Time is both gatekeeper to space and father of multiple truths.
