" "Perhaps the records will never be intercepted. Perhaps no one in five billion years will ever come upon them. Five billion years is a long time. In five billion years, all human beings will have become extinct or evolved into other beings, none of our artifacts will have survived on Earth, the continents will have become unrecognizably altered or destroyed, and the evolution of the Sun will have burned the Earth to a crisp or reduced it to a whirl of atoms.
Far from home, untouched by these remote events, the Voyagers, bearing the memories of a world that is no more, will fly on.

About Carl Sagan
Carl Edward Sagan (9 November 1934 – 20 December 1996) was an American astronomer, planetary scientist, cosmologist, astrophysicist, astrobiologist, author, and science communicator. His best known scientific contribution is research on extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by radiation. Sagan assembled the first physical messages sent into space, the Pioneer plaque and the Voyager Golden Record, universal messages that could potentially be understood by any extraterrestrial intelligence that might find them. Sagan argued the hypothesis, accepted since, that the high surface temperatures of Venus can be attributed to, and calculated using, the greenhouse effect. He testified to the US Congress in 1985 that the greenhouse effect will change the earth's climate system.

Additional quotes by Carl Sagan
More praise for The Demon-Haunted World “As I close this eloquent and fascinating book, I recall the final chapter title from one of Carl Sagan’s earlier works, Cosmos. ‘Who Speaks for Earth?’ is a rhetorical question, but I presume to answer it. My candidate for planetary ambassador can be none other than Carl Sagan himself. He is wise, humane, witty, well read, and incapable of composing a dull sentence.… I wish I had written The Demon-Haunted World. Having failed to do so the least I can do is press it upon my friends. Please read this book.” — Richard Dawkins The Times (London)
