How can you predict the future?

When the data is complete and the processing power of the computer is fast, we can predict the future, which is actually to simulate what will happen in the future. For a simple example, a small ball falls from a height of 5 meters and then hits a piece of glass on the ground. If we can accurately input the initial speed of the ball falling and some external forces and know the bearing capacity of the glass, we can simulate this process on the computer, and it is exactly the same as the real process. Enlarge your mind a little more. If you input all the information about a person's psychological state and his environment, you can simulate how a person will handle some things! In the future, I think this thing is not a dream.
