“I have a vision of a Galaxy overrun by mankind from Core to rim. Of four hundred billion stars each enslaved to the rhythm of Earth's day, Earth's year. I have a vision of a trillion planets pulsing to the beat of a human heart.”

“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.”

“I know a lot of things, Mathilda. I have gazed through space telescopes into the heart of the galaxy. I have seen a dawn of four hundred billion suns. It all means nothing without life. You and I are special, Mathilda. We are alive.”

“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.”

“Long ago, when an early galaxy began to pour light out into the surrounding darkness, no witness could have known that billions of years later some remote clumps of rock and metal, ice and organic molecules would fall together to make place called Earth; or that life would arise and thinking beings evolve who would one day capture a little of that galactic light, and try to puzzle out what had sent it on its way. And after the earth dies, some 5 billion years from now, after it's burned to a crisp, or even swallowed by the Sun, there will be other worlds and stars and galaxies coming into being -- and they will know nothing of a place once called Earth.”

“The atoms of our bodies are traceable to stars that manufactured them in their cores and exploded these enriched ingredients across our galaxy, billions of years ago. For this reason, we are biologically connected to every other living thing in the world. We are chemically connected to all molecules on Earth. And we are atomically connected to all atoms in the universe. We are not figuratively, but literally stardust.”
