"To expect alien technology to be just a few decades ahead of ours is too incredible to be taken seriously."
"It has become appallingly obvious that our technology has exceeded our humanity."Paul Davies on Albert Einstein
"The typewriting machine, when played with expression, is no more annoying than the piano when played by a sister or near relation."Paul Davies on Oscar Wilde
"Any sufficiently advanced technology is indistinguishable from magic."Paul Davies on Arthur C. Clarke
"The world is very different now. For man holds in his mortal hands the power to abolish all forms of human poverty, and all forms of human life."Paul Davies on John F. Kennedy
"I am sorry to say that there is too much point to the wisecrack that life is extinct on other planets because their scientists were more advanced than ours."Paul Davies on John F. Kennedy
"The way life manages information involves a logical structure that differs fundamentally from mere complex chemistry. Therefore chemistry alone will not explain life's origin, any more than a study of silicon, copper and plastic will explain how a computer can execute a program."
"Perhaps the best motivation for going to Mars is political. It is obvious that no single nation currently has either the will or the resources to do it alone, but a consortium of nations and space agencies could achieve it within 20 years."
"Should we find a second form of life right here on our doorstep, we could be confident that life is a truly cosmic phenomenon. If so, there may well be sentient beings somewhere in the galaxy wondering, as do we, if they are not alone in the universe."
"Man-made computers are limited in their performance by finite processing speed and memory. So, too, the cosmic computer is limited in power by its age and the finite speed of light."
"Science, we are repeatedly told, is the most reliable form of knowledge about the world because it is based on testable hypotheses. Religion, by contrast, is based on faith. The term 'doubting Thomas' well illustrates the difference."
