The light from the Sun takes approximately 8:19 minutes to reach the Earth. So what were looking at, is actually the Sun from 8 minutes before. And the stars, the ones far far away... the ones which are more than a hundred million light years away... arent we seeing them as they must have appeared so many millions of years ago? If someone from those distant rocks waved at us, well receive his greetings when he would have moved on, many millennia ago. I daresay, the Night Sky is, in the best sense, a window to the past... a time machine!
