“We inhabit a universe where atoms are made in the centers of stars; where each second a thousand suns are born; where life is sparked by sunlight and lightning in the airs and waters of youthful planets; where the raw material for biological evolution is sometimes made by the explosion of a star halfway across the Milky Way; where a thing as beautiful as a galaxy is formed a hundred billion times - a Cosmos of quasars and quarks, snowflakes and fireflies, where there may be black holes and other universe and extraterrestrial civilizations whose radio messages are at this moment reaching the Earth. How pallid by comparison are the pretensions of superstition and pseudoscience; how important it is for us to pursue and understand science, that characteristically human endeavor. ”

“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.”

“...he asked, "Where are you today, right now?"Eagerly, I started talking about myself. However, I noticed that I was still being sidetracked from getting answers to my questions. Still, I told him about my distant and recent past and about my inexplicable depressions. He listened patiently and intently, as if he had all the time in the world, until I finished several hours later."Very well," he said. "But you still have not answered my question about where you are.""Yes I did, remember? I told you how I got to where I am today: by hard work.""Where are you?""What do you mean, where am I?""Where Are you?" he repeated softly."I'm here.""Where is here?""In this office, in this gas station!" I was getting impatient with this game."Where is this gas station?""In Berkeley?""Where is Berkeley?""In California?""Where is California?""In the United States?""On a landmass, one of the continents in the Western Hemisphere. Socrates, I...""Where are the continents?I sighed. "On the earth. Are we done yet?""Where is the earth?""In the solar system, third planet from the sun. The sun is a small star in the Milky Way galaxy, all right?""Where is the Milky Way?""Oh, brother, " I sighed impatiently, rolling my eyes. "In the universe." I sat back and crossed my arms with finality."And where," Socrates smiled, "is the universe?""The universe is well, there are theories about how it's shaped...""That's not what I asked. Where is it?""I don't know - how can I answer that?""That is the point. You cannot answer it, and you never will. There is no knowing about it. You are ignorant of where the universe is, and thus, where you are. In fact, you have no knowledge of where anything is or of What anything is or how is came to be. Life is a mystery."My ignorance is based on this understanding. Your understanding is based on ignorance. This is why I am a humorous fool, and you are a serious jackass.”

“We live on a hunk of rock and metal that circles a humdrum star that is one of 400 billion other stars that make up the Milky Way Galaxy which is one of billions of other galaxies which make up a universe which may be one of a very large number, perhaps an infinite number, of other universes. That is a perspective on human life and our culture that is well worth pondering.”

“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.”

“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.”
