Let’s say NASA builds a 99.999999% speed of light ship. They enlist me to travel in it as I fly off to distant stars. So that I’ll have something to keep me occupied, they give me an analog TV and mount a TV antenna on the outside so I can watch the broadcast TV that has been streaming out from Earth. As I’m flying along at 99.9999% SOL and turn on the TV, what would the shows look like? Assume NASA has provided some sort of converter box between the antenna and TV to handle any sort of change in frequencies. Will the shows be normal speed, slow motion, or fast motion?
Anyone remember the unused channels from back in the 70’s that just showed a clock and temperature? Say I was watching that channel on the launchpad. I set my wristwatch to exactly the time I see on the clock on TV. My ship blasts off and I’m soon at 99.9999999% SOL. How will the time on my watch change vs the time on the clock on TV?
