" "We have examined the universe in space and seen that we live on a mote of dust circling a humdrum star in the remotest corner of an obscure galaxy. And if we are a speck in the immensity of space, we also occupy an instant in the expanse of ages. We now know that our universe or at least its most recent incarnation - is some fifteen or twenty billion years old. This is the time since a remarkable explosive event called the Big Bang. At the beginning of this universe, there were no galaxies, stars or planets, no life or civilizations, merely a uniform, radiant fireball filling all of space. The passage from the Chaos of the Big Bang to the Cosmos that we are beginning to know is the most awesome transformation of matter and energy that we have been privileged to glimpse. And until we find more intelligent beings elsewhere, we are ourselves the most spectacular of all the transformations - the remote descendants of the Big Bang, dedicated to understanding and further transforming the Cosmos from which we spring

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
But before the grandeur and intricacy of Nature, he was, like Ptolemy and Kepler, exhilarated as well as disarmingly modest. Just before his death he wrote: “I do not know what I may appear to the world; but to myself I seem to have been only like a boy, playing on the seashore, and diverting myself, in now and then finding a smoother pebble or a prettier shell than ordinary, while the great ocean of truth lay all undiscovered before me.

Nuevamente, la razón por la que la ciencia funciona tan bien es en parte este mecanismo incorporado de corrección de errores. En la ciencia no hay preguntas prohibidas, no hay temas demasiado sensibles o delicados para ser explorados, no hay verdades sagradas. Esta apertura a nuevas ideas, combinada con el escrutinio más riguroso y escéptico de todas las ideas, selecciona el trigo de la cizaña. No importa lo inteligente, venerable o querido que sea uno. Debe demostrar sus ideas ante la crítica decidida y experta. Se valoran la diversidad y el debate. Se alienta la formulación de opiniones en disputa, sustantivamente y en profundidad.
