Some people claim to be able to see into the future.
According to the Greeks, our fate was predetermined, as in the tragic story of Oedipus killing his father and marrying his mother. In the very attempt to alter his course, he caused it to happen. In the classical view of physics, as long as the initial conditions are known, the characteristics of any other time can be determined. For example, suppose you throw a ball in some direction or other. Given enough information about the starting system, any point in the future can be determined.
