Certainly, but one of the two parties is moving relative to the inertial
reference frame and one is not. Am I correct in thinking that the occupant
of the ship will experience Doppler Shift of light while the "stationary"
observer will not? Might that be the determining factor?
In any case, experimental evidence has borne out the prediction that time
will dilate for a body accelerating toward the speed of light--not the
stationary observer on the ground.
Dave!

Then, say we have a spaceship, moving at half the speed of light relative to (...) (24 years ago, 8-Nov-00, to lugnet.off-topic.geek)
