This truely is fascinating. If by what people are saying, if moving 10 lightyears away from earth, and looking at earth, you see 10 years into the past. But its not actually that because it just takes that long for the light reflections from 10 years ago to reach your current point. If this applys to looking at places from earth, we could technically see the beggining of the universe with a powerful enough telescope. Oh, a question I just thought of... If we somehow placed a very big mirror 100 lightyears from Earth, and looked at that mirror from earth and saw earths reflection... Would you see earth as it was 100 years ago, or would it be at its current state?
