“No one was able to give him an answer, nor from that day did anyone dare to ask him any more questions.”
Carl Sagan was a popular 20th-century writer, astronomer, and exobiologist. He cultivated an infectious enthusiasm for popular science, and he encouraged people to ask big questions about the universe, and humanity’s place in the universe. Sagan was the one who persuaded NASA to turn their Voyager 1 space probe around to photograph Earth from a distance of 3.7 billion miles, giving humanity the astonishing image of a “pale blue dot,” our tiny home, aloft and alone in the vast preserve of outer space. Years before that, Sagan led the development of the Golden Record, an artifact placed on board that same Voyager probe (as well as Voyager 2), containing information about us and our planet for potential discovery by extra-terrestrial species, who might one day intercept our wondrous inventions.
In Carl Sagan’s book, The Demon-Haunted World: Science as a Candle in the Dark, he writes, “There are naïve questions, tedious questions, ill-phrased questions, questions put after inadequate self-criticism. But every question is a cry to understand the world. There is no such thing as a dumb question.”
