Would the time required for a photon to travel from one side of the
ship to the other side be ;

(1) One second according to the ship's clock? or
(2) One second according to a clock on Earth? or
(3) One second according to both clocks? or
(4) Some arbitrary time not related to the nominal speed of light?


It depends on whether you assume Minkowski or Euclidean space.
