Hello - Not sure if this is the correct location for this. I've been thinking about how a radio wave would work as the transmitter travels further away from the receiver. My example is a transmitter on a spaceship traveling 60,000 kph that transmits a loop of my favorite playlist back to earth. After ~18,000 hours, the spaceship will be about a light-hour away. What would I hear on earth? Does the transmission sound 0.0055% slower on earth to compensate for the speed of the spaceship, so when it's streaming from 1 light-hour away, the delay has already been included in the playback? Would this also change the radio frequency I would need to "tune-in" to a lower frequency than what's being transmitted based on how fast the spaceship is moving? Thanks!
