Has the Future Already Happened?

From an individual point of view, time moves in a line from your past to the present and then into the future. All we experience is the present, but we remember the past, and anticipate the future -although we cannot know it until it is the present. But the theory of relativity states that time moves differently for beings moving faster through space, so is their "present" different from ours? And how would different "presents" work? The idea of multiple presents warps the idea of an unknowable future that can be affected by the choices we make in the present. If that's too mind-blowing, maybe we should look at time in a different way to make it mesh with our lived experience. Then there's always the possibility that we are wrong, but how would we ever know?

Sometimes I try to picture how God sees his universe in four dimensions from the beginning to the end of time, and it looks silly because we can't picture time, and we can't render four dimensions in an image. Kurzgesagt gives it the old college try, though. (via Digg)
