Now, I want to tell you something about the importance of this new structure in quantum mechanics. And in doing so I will imitate Einstein by talking about God. I do not want to do anything about religious convictions. I am using the concept of God because that concept and some of its consequences are common knowledge. My statement of the great change is this: physicists in the last century, believing what they believed, had to believe that if God existed, He was unemployed, because ten billion years ago He created the universe, together with cause and effect relations. Whatever He did at that time determines the whole future to any accuracy you please and God cannot change that, except by violating the principles of physics, which we like to call a miracle. So, within the description of physics, old fashioned physics, with the future determined, we'll- did not allow for any concept like God who can do something. The contest is that in quantum mechanics the future is not determined. From microsecond to microsecond there are changes that cannot be predicted. As physicists, we don't say anything about good or evil, we don't want to judge what can happen, but we can say that the future is not determined. This is a very simple statement. And I think it is a statement that everyone should understand, that this is the real structure of the world.
