Question about the movie "Paycheck" I was watching this movie last night "paycheck" and got to a point in the movie which made me kinda confused. They said something about building a new type of lens that could basicaly curved around the earth. For example- your on top of Mt. Everest and when you look through the lens, you would see yourself in the future. I can't figure out how you could see yourself in the future. Can someone help me out?
