Summary

[edit]
Description
English: Schematic of the (3+1)D traveler kinematic for describing changes in map-position x regardless of speed[1] using the traveler's perspective on time τ, velocity dx/dτ, and proper-acceleration α. The method outlined here should in principle work with other metric equations as well.
