|also if astronaights are in space does that mean there actually looking into the past when looking at tue earth?|
Let's not forget to factor in the extremely small amount of gravitational time dilation. On Earth, time is moving slower than up in space due the lower gravitational potential. It's much more obvious in tremendous gravitational fields such as that of a black hole. I only have a minor understanding of these concepts since I'm merely a baby physicist but it's still damn interesting and something to factor in when speaking of astronauts 'looking into the past' since we even have to factor it in when calibrating GPS.
Maybe someone else could correct me or add to what I've said?
