Hello guys I'm just wondering about an optical concept in a fictional movie I've watched. In the movie, there was a machine invented to be able to see someone’s future. The optical concept about this machine is the power of lenses which enable the user to view the light that came from here, on earth, except that this light had already revolved around the universe. It was said in the movie that when this light is viewed, you’ll be ale to see the future. My problem is this: in my study in optics, it’s really possible to see someone’s or something’s past, like the stars we’re seeing every night, but how come you’ll be able to see your future? I know that this movie is fictional but I’m just wondering if there’s really an explanation in physics about this. :uhh: Thanks for reading and I’ll appreciate any of your humble replies. Anyways, the movie was Paycheck, one of my favorite movies about physics.
