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.
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.

Dicho de otro modo, cualquier predisposición a la creencia religiosa puede verse poderosamente influida por la cultura indígena, viva uno donde viva. Especialmente si los niños están expuestos desde muy pequeños a una serie concreta de doctrinas, música, arte y ritual, es algo tan natural para ellos como respirar, motivo por el cual las religiones hacen tantos esfuerzos para atraer a los más jóvenes.
Human speech is like a cracked kettle on which we tap crude rhythms for bears to dance to, while we long to make music that will melt the stars

Do you believe in UFOs?’ I’m always struck by how the question is phrased, the suggestion that this is a matter of belief and not of evidence. I’m almost never asked, ‘How good is the evidence that UFOs are alien spaceships?
