The open universe is after the impossible. What you thought that it was impossible was a kind of infinity. But infinity isn’t an obstruction. It’s possible to reach it. It’s not a question of imagination. Even the fantastic is very short in front of this reality. It’s just a question of faith. If you really believe, you will see that the impossible is not the end. It’s just a change like infinity. Because after it you will discover many others. The first step is to believe before the first miracle because the rest will be the history of the  future of Mankind.
