Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.

In the beginning the Universe was created. This has made a lot of people very angry and has been widely regarded as a bad move.

Once you can accept the universe as matter expanding into nothing that is something, wearing stripes with plaid comes easy.

Just because some of us can read and write and do a little math, that doesn't mean we deserve to conquer the Universe.

There is a theory which states that if ever anyone discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable.

There is another theory which states that this has already happened.

Mathematics is the language with which God has written the universe.

The arts put man at the center of the universe, whether he belongs there or not. Military science, on the other hand, treats man as garbage— and his children, and his cities, too. Military science is probably right about the contemptibility of man in the vastness of the universe. Still— I deny that contemptibility, and I beg you to deny it, through the creation of appreciation of art.

To be
the eyes
and ears
and conscience
of the Creator of the Universe,
you fool. Kilgore Trout's unwritten reply to the question "What is the purpose of life?"

We are just an advanced breed of monkeys on a minor planet of a very average star. But we can understand the Universe. That makes us something very special. (1988-10-17)

The universe is a lot more complicated than you might think even if you start from a position of thinking that its pretty damn complicated to begin with.

If the stars should appear one night in a thousand years, how would men believe and adore, and preserve for many generations the remembrance of the city of God which had been shown! But every night come out these envoys of beauty, and light the universe with their admonishing smile.

Ere many generations pass, our machinery will be driven by a power obtainable at any point of the universe. This idea is not novel. Men have been led to it long ago by instinct or reason; it has been expressed in many ways, and in many places, in the history of old and new. We find it in the delightful myth of Antheus, who derives power from the earth; we find it among the subtle speculations of one of your splendid mathematicians and in many hints and statements of thinkers of the present time. Throughout space there is energy. Is this energy static or kinetic! If static our hopes are in vain; if kinetic — and this we know it is, for certain — then it is a mere question of time when men will succeed in attaching their machinery to the very wheelwork of nature.

Sometimes I think we're alone in the universe, and sometimes I think we're not. In either case the idea is quite staggering.

What I have done is to show that it is possible for the way the universe began to be determined by the laws of science. In that case, it would not be necessary to appeal to God to decide how the universe began. This doesn't prove that there is no God, only that God is not necessary. (1988-10-17)

"Not that anyone cares what I say, but the Restaurant is on the other end of the universe"

Alas! Your dear friend and servant Galileo has been for the last month hopelessly blind; so that this heaven, this earth, this universe, which I by my marvelous discoveries and clear demonstrations had enlarged a hundred thousand times beyond the belief of the wise men of bygone ages, henceforward for me is shrunk into such a small space as is filled by my own bodily sensations.

I'm sure the universe is full of intelligent life. It's just been too intelligent to come here.

Mere opinions, in fact, were as likely to govern people's actions as hard evidence, and were subject to sudden reversals as hard evidence could never be. So the Galapagos Islands could be hell in one moment and heaven in the next, and Julius Caesar could be a statesman in one moment and a butcher in the next, and Ecuadorian paper money could be traded for food, shelter, and clothing in one moment and line the bottom of a birdcage in the next, and the universe could be created by God Almighty in one moment and by a big explosion in the next— and on and on.

If we do discover a complete theory, it should in time be understandable in broad principle by everyone, not just a few scientists. Then we shall all, philosophers, scientists, and just ordinary people, be able to take part in the discussion of the question of why it is that we and the universe exist. If we find the answer to that, it would be the ultimate triumph of human reason — for then we would know the mind of God.

Even if there is only one possible unified theory, it is just a set of rules and equations. What is it that breathes fire into the equations and makes a universe for them to describe? The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing?

One could say: "The boundary condition of the universe is that it has no boundary." The universe would be completely self-contained and not affected by anything outside itself. It would neither be created nor destroyed. It would just BE.

We are the miracle of force and matter making itself over into imagination and will. Incredible. The Life Force experimenting with forms. You for one. Me for another. The Universe has shouted itself alive. We are one of the shouts.

When you want something, all the universe conspires in helping you to achieve it.

Jupiter's fly-by had been carried out with impeccable precision. Like a ball on a cosmic pool table, Discovery had bounced off the moving gravitational field of Jupiter, and had gained momentum from the impact. Without using any fuel, she had increased her speed by several thousand miles an hour.

Yet there was no violation of the laws of mechanics; Nature always balances her books, and Jupiter had lost exactly as much momentum as Discovery had gained. The planet had been slowed down - but as its mass was a sextillion times greater than the ship's, the change in its orbit was far too small to be detectable. The time had not yet come when Man could leave his mark upon the Solar System.

Belief is nearly the whole of the Universe, whether based on truth or not.
