Assuming movement through a perfect vacuum with standard pressure, if you have two objects, one moving at .5c relative to Barnard's Star and beginning at ref point {0,0,0,now} and moving directly south, and the second object moving at .95c relative to Russell's Teapot from {12,19,65295,6 hours ago} toward galactic north, and a privileged observer with telescopes trained on both of them but a headache from trying to understand this problem, what crime has the privileged observer been framed for?
