Hey, I've got a hypothetical question: let's say that you developed: a) a super powerful telescope that can detect earth-sized planets even billions of light years away; and b) faster than light space travel. You should be able to mount your telescope to your spaceship, travel 4.5 billion light years away, and then turn around and observe the creation of the earth, correct? Is there anything wrong with that scenario, other than that such a telescope and such a spaceship are both almost inconceivable?
