Foreword: there is no intention here to present a trick question or anything of the sort. This is intended to be an analysis of photon motion on a path perpendicular to the motion of its source on theoretical physics grounds. This gedanken thought science experiment consists of a straight and practically rigid pipe .99 meter in diameter and 9,999 meters long, coated inside with material that absorbs any photon and capped on one end with a photon detector and counter. On the other end is a Xaser ( a hard X-ray laser ) adjusted to fire single photons. During manufacture the Xaser is aimed dead center on the end cap. The pipe is tightly packed full of pure vacuum. The entire assembly is painted with special pigment that completely absorbs any external photon or any substance that could create a photon inside. The assembly is mounted on an Enterprise class starship with its major axis perfectly perpendicular to the fore and aft axis of the starship. It looks like the starship has a long skinny pipe for a wing. The science experiment modus operandi is for the starship to execute a high speed fly by, on a straight path, past the Earth at a closest approach of 99,999 kilometers while stationary obversation station area observers on the ground observe it. The starship will fly on impulse only but will activate the forward asteroid deflector shield to ward off any and all disturbance from oncoming photons, cosmic rays, or anything else. It will build up speed and make a long fly by at .9999c, according to the observers. The experiment has been rehersed repeatedly to obtain timing parameters and the team is confident that that programming of automatic controllers on the starship will give perfect coordination. During the fly by, when the starship is nearest the Earth, the controllers will trigger the Xaser to fire one photon. To be doubly and unnecessarily repetetively redundant, the pipe is exactly perpendicular to the starship flight path. When the starship lands at the stationary observer station area, the stationary observers will probably rush over to to it at an average, or drift, velocity of about 9.9 kilometers per hour and anxiously examine the photon detector and counter on the end cap. How many photon strikes will the counter show for the result of this experiment and why?
