I hope that every [person] at one point in their life has the opportunity to have something that is at the heart of their being, something so central to their being that if they lose it they won't feel they're human anymore, to be proved wrong because that's the liberation that science provides.

In 5 billion years, the expansion of the universe will have progressed to the point where all other galaxies will have receded beyond detection. Indeed, they will be receding faster than the speed of light, so detection will be impossible. Future civilizations will discover science and all its laws, and never know about other galaxies or the cosmic background radiation. They will inevitably come to the wrong conclusion about the universe......We live in a special time, the only time, where we can observationally verify that we live in a special time.
