I was thinking, how would a phone call work from space to earth over super vast distances? It's been in my mind for a minute, because of time dilation (I think that's what it's called). If I was X light years away from earth, wouldn't it take X time for me to say "hi, how are you?" broadcasted down to earth?

If I explained it poorly, I'm sorry. I'm not certain how to put it into the right words lol.
