"By looking far out into space we are also looking far back into time, back toward the horizon of the universe, back toward the epoch of the Big Bang."

"And you are made of a hundred trillion cells. We are, each of us, a multitude."

"The lifetime of a human being is measured by decades, the lifetime of the Sun is a hundred million times longer. Compared to a star, we are like mayflies, fleeting ephemeral creatures who live out their lives in the course of a single day."

"When we look up at night and view the stars, everything we see is shinning because of distant nuclear fusion."
