When you look into a mirror, it is a reflection of the past because of the time delay (light reflection from eyes - mirror - eyes). Similarly when you gaze into the sky through a telescope, if you're looking at a star that's 10 light-years away, the light you see left that star 10 years ago. And so I’ve always wondered, if we sent rockets to outer space 10 light-years away looking back at Earth (through a telescope), could we get a visible glance of history and set the records straight ?
