“If a human disagrees with you, let him live. In a hundred billion galaxies, you will not find another.”

“Every one of us is, in the cosmic perspective, precious. If a human disagrees with you, let him live. In a hundred billion galaxies, you will not find another.”

“The lessons of rocks, stars,and life are clear. To understand Earth, you must divorce yourself for the inconsequential temporal or spacial scale of human life. We live on a single tiny world in a cosmos of a hundred billion galaxies, each with a hundred billion stars. Similarly, we live day by day in a cosmos aged hundreds of billions of days. If you seek meaning and purpose in the cosmos, you will not find it in any privileged moment or place tied to human existence.”

“Whenever I saw the sun, I reminded myself that I was looking at a star. One of over a hundred billion in our galaxy. A galaxy that was just one of billions of other galaxies in the observable universe. This helped me keep things in perspective.”

“Our sun is one of a 100 billion stars in our galaxy. Our galaxy is one of billions of galaxies populating the universe. It would be the height of presumption to think that we are the only living thing in that enormous immensity.”

“If such a thing had happened once, it must surely have happened many times in this galaxy of a hundred billion suns.”
