When the spaceship is a bit over 186,000 miles from earth the video will be received 1 second after it was generated. Double that distance and the delay will be 2 seconds.
And so on.
Light and radio signals travel at about 186,000 miles per second. That’s really all you need to know.
Everything you see is “in the past”.
“Everything you see is “in the past”.”
True that is and very few of us ever pause to consider it but we never see anything as it occurs. Even if it is only ten feet away we see what happened in the immediate past. We hear what happened much further in the past than what we see. I used to watch thunderstorms and count the time between the flash of lightning and the thunder. It can be several seconds.
