I remember that in one of the DVD commentaries on Futurama, the crew make reference to drawing inspiration from a story that goes something like this:
A man with a high-powered telescope observes an alien woman on a distant planet and falls in love with her. Eventually, he realises that due to the time it takes light to travel from the planet to Earth, everything he's seen will have taken place millions of years in the past and that the woman is surely long dead.
I've always thought that this idea is a beautiful way of thinking of the way we observe the universe, but I can't for the life of me remember what the story was called, and I don't have access to the Futurama DVDs any more.
Is anyone familiar with this story?
