En el mismo momento en que el hombre descubrió la vastedad del universo y se dio cuenta de que aun sus más disparatadas fantasías eran ínfimas comparadas con la verdadera dimensión de la Vía Láctea, tomó medidas para asegurar que sus descendientes no pudiesen ver las estrellas en lo más mínimo. Durante un millón de años, los humanos se han criado en el contacto diario, personal, con la bóveda celeste. En los últimos milenios comenzaron a construir las ciudades y a emigrar hacia ellas. En el curso de las últimas décadas, gran parte de la población humana abandonó una forma rústica de vida. A medida que avanzaba la tecnología y se contaminaban los centros urbanos, las noches se fueron quedando sin estrellas. Nuevas generaciones alcanzaron la madurez ignorando totalmente el firmamento que había pasmado a sus mayores y estimulado el advenimiento de la era moderna de la ciencia y la tecnología. Sin darse cuenta siquiera, justo cuando la astronomía entraba en su edad de oro, la mayoría de la gente se apartaba del cielo en un aislamiento cósmico que sólo terminó con los albores de la exploración espacial.

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

The total number of such worlds are, as I said, something of the order of a trillion, or 10^12, a one followed by twelve zeros, of which Earth represents just one, all in the family of the Sun. And our star, of course, is one of a vast multitude.

Alone in the observatory late one night, I heard the telephone ring persistently. When I answered, a voice, betraying a well-advanced state of inebriation, said, “Lemme talk to a shtrominer.” “Can I help you?” “Well, see, we’re havin’ this garden party out here in Wilmette, and there’s somethin’ in the sky. The funny part is, though, if you look straight at it, it goes away. But if you don’t look at it, there it is.” The most sensitive part of the retina is not at the center of the field of view. You can see faint stars and other objects by averting your vision slightly. I knew that, barely visible in the sky at this time, was a newly discovered comet called Arend-Roland. So I told him that he was probably looking at a comet. There was a long pause, followed by the query: “Wash’ a comet?” “A comet,” I replied, “is a snowball one mile across.” There was a longer pause, after which the caller requested, “Lemme talk to a real shtrominer.
