“If you could be president of the universe, would you accept? We're all cursed to be president of our universe in our own right; in some sense, I already have. But that doesn't mean just me and no one else.”
“If you ever start taking things too seriously, just remember that we are talking monkeys on an organic spaceship flying through the universe.”
“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.”
“There is a theory which states that if ever anyone discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable. There is another theory which states that this has already happened.”
“There is no absolute up or down; no absolute position in space; but the position of a body is relative to that of other bodies. Everywhere there is incessant relative change in position throughout the universe, and the observer is always at the center of things.”
“There is only one corner of the universe you can be certain of improving, and that's your own self.”
“Two possibilities exist: either we are alone in the universe or we are not. Both are equally terrifying.”
“Two things fill the mind with ever-increasing wonder and awe, the more often and the more intensely the mind of thought is drawn to them: the starry heavens above me and the moral law within me.”
“The sun, with all those planets revolving around it and dependent on it, can still ripen a bunch of grapes as if it had nothing else in the universe to do.”
“The only true voyage of discovery, the only fountain of eternal youth, would be not to visit strange lands but to possess new eyes; to behold the universe through the eyes of another—of a hundred others—to behold the hundred universes that each of them beholds, that each of them is.”
“There are only two ways to live your life. One is as though nothing is a miracle. The other is as though everything is a miracle.”
“There are only 3 things in the universe: the known-knowns, the known-unknowns, and the unknown-unknowns. What we know, what we don't know, and what we don't know we don't know.”
“Deep in the human unconscious is a pervasive need for a logical universe that makes sense. But the real universe is always one step beyond logic.”
