“A galaxy is composed of gas and dust and stars - billions upon billions of stars. Every star may be a sun to someone.”

“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.”

“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.”

“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.”

“Her universe is such a big place full of so many galaxies-100 billion of them with 100 billion stars apiece which means 10 to the 22nd power stars-that it’s terrifying to think of the odds that we found each other. We want to freeze the perfect moment hold on to it at least long enough to understand it. But it dances on with us or without us so we jump in and try to keep up. The universe is expanding and we are just two of a billion stars.”

“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.”
