"Your Excellency, I have no need of this hypothesis."

"The reappearance of the crescent moon after the new moon; the return of the Sun after a total eclipse, the rising of the Sun in the morning after its troublesome absence at night were noted by people around the world; these phenomena spoke to our ancestors of the possibility of surviving death. Up there in the skies was also a metaphor of immortality."

"The near side of a galaxy is tens of thousands of light-years closer to us than the far side; thus we see the front as it was tens of thousands of years before the back. But typical events in galactic dynamics occupy tens of millions of years, so the error in thinking of an image of a galaxy as frozen in one moment of time is small."

"Discover the force of the skies O Men: once recognised it can be put to use."

"Love is only one fine star away."

"The bright sun was extinguish'd, and the starsDid wander darkling in the eternal space."

"Napoleon, when hearing about Laplace's latest book, said, 'M. Laplace, they tell me you have written this large book on the system of the universe, and have never even mentioned its creator.'Laplace responds, 'Je n'avais pas besoin de cette hypothèse-là. (I had no need of that hypothesis.)"

"Any patch of sunlight in a wood will show you something about the sun which you could never get from reading books on astronomy. These pure and spontaneous pleasures are ‘patches of Godlight’ in the woods of our experience."

"Interviewer: Didn't Sagan want to believe?Druyan: he didn't want to believe. he wanted to know."

"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."

"Some piously record 'In the beginning God', but I say 'In the beginning hydrogen'."

"There's no obvious reason to assume that the very same rare properties that allow for our existence would also provide the best overall setting to make discoveries about the world around us. We don't think this is merely coincidental. It cries out for another explanation, an explanation that... points to purpose and intelligent design in the cosmos."

"If the stars should appear one night in a thousand years, how would men believe and adore; and preserve for many generations the remembrance of the city of God which had been shown! But every night come out these envoys of beauty, and light the universe with their admonishing smile."

"The discovery of a new dish does more for the happiness of the human race than the discovery of a star."

"It's amazing to me that we humans have the intellectual capacity to ask deep questions and to devise methods for learning how the universe works and how its contents evolve with time."

"The Earth is cylindrical, three times as wide as it is deep, and only the upper part is inhabited. But this Earth is isolated in space, and the sky is a complete sphere in the center of which is located, unsupported, our cylinder, the Earth, situated at an equal distance from all the points of the sky."

"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."

"My dear Kepler, what would you say of the learned here, who, replete with the pertinacity of the asp, have steadfastly refused to cast a glance through the telescope? What shall we make of this? Shall we laugh, or shall we cry?"

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

"To respect a mystery is to make way for the answer."
