From my understanding the image we see of a star isn't a reflection of how that star is now. The image we are seeing of those stars is millions, or billions of years old because it's taken that long for the light from the star to reach us. Is this correct?
But, let's say we could travel to one of these stars, one that still exists. If we could travel there in an hour, and looked back at the Earth through a powerful telescope what would we see? Would we see the past on earth?
Would it be true that further we travel back from the earth, the more of the past we would see because it's taking longer and longer for the present light from Earth to reach that point in space where we would theoretically be looking from?
