Two possibilities exist: Either we are alone in the Universe or we are not. Both are equally terrifying.
I'm sure the universe is full of intelligent life. It's just been too intelligent to come here.
There is no reason to assume that the universe has the slightest interest in intelligence—or even in life. Both may be random accidental by-products of its operations like the beautiful patterns on a butterfly's wings. The insect would fly just as well without them.
Sometimes I think we're alone in the universe, and sometimes I think we're not. In either case the idea is quite staggering.
All human plans [are] subject to ruthless revision by Nature, or Fate, or whatever one preferred to call the powers behind the Universe.
The universe must be full of voices, calling from star to star in a myriad tongues. One day we shall join that cosmic conversation.
The choice, as Wells once said, is the Universe-or nothing. . . . The challenge of the great spaces between the worlds is a stupendous one; but if we fail to meet it, the story of our race will be drawing to its close. Humanity will have turned its back upon the still untrodden heights and will be descending again the long slope that stretches, across a thousand million years of time, down to the shores of the primeval sea.
When you finally understand the universe, it will not only be stranger than you imagine, it will be stranger than you can imagine.
I sometimes think that the universe is a machine designed for the perpetual astonishment of astronomers.
Deep beneath the surface of the Sun, enormous forces were gathering. At any moment, the energies of a million hydrogen bombs might burst forth in the awesome explosion.... Climbing at millions of miles per hour, an invisible fireball many times the size of Earth would leap from the Sun and head out across space.
Even if we never reach the stars by our own efforts, in the millions of years that lie ahead it is almost certain that the stars will come to us. Isolationism is neither a practical policy on the national or cosmic scale. And when the first contact with the outer universe is made, one would like to think that Mankind played an active and not merely a passive role-that we were the discoverers, not the discovered.
In this universe the night was falling; the shadows were lengthening towards an east that would not know another dawn. But elsewhere the stars were still young and the light of morning lingered; and along the path he once had followed, Man would one day go again.
He found it both sad and fascinating that only through an artificial universe of video images could she establish contact with the real world.
God said, 'Cancel Program GENESIS.' The universe ceased to exist.
In all the universe there is nothing more precious than mind.
The best proof that there's intelligent life in the universe is that it hasn't come here.
They will have time enough, in those endless aeons, to attempt all things, and to gather all knowledge... no Gods imagined by our minds have ever possessed the powers they will command... But for all that, they may envy us, basking in the bright afterglow of Creation; for we knew the Universe when it was young.
In the long run, there are no secrets. in science. The universe will not cooperate in a cover-up.
