It has been discovered that all the world is made of the same atoms, that the stars are of the same stuff as ourselves. It then becomes a question of where our stuff came from. Not just where did life come from, or where did the earth come from, but where did the stuff of life and of the earth come from?

Observe constantly that all things take place by change, and accustom thyself to consider that the nature of the Universe loves nothing so much as to change the things which are, and to make new things like them.

All the evidence, experimental and even a little theoretical, seems to indicate that it is the energy content which is involved in gravitation, and therefore, since matter and antimatter both represent positive energies, gravitation makes no distinction.

When a person really desires something, all the universe conspires to help that person to realize his dream.

When we understand string theory, we will know how the universe began. It won’t have much effect on how we live, but it is important to understand where we come from and what we can expect to find as we explore.

I don’t pretend to understand the Universe – it’s a great deal bigger than I am.

It’s a pity that nobody has found an exploding black hole. If they had, I would have won a Nobel prize.

I want to know why the universe exists, why there is something greater than nothing.

The universe is transformation: life is opinion.

Poetry is the art of substantiating shadows, and of lending existence to nothing.

Throughout history, people have studied pure science from a desire to understand the universe rather than practical applications for commercial gain. But their discoveries later turned out to have great practical benefits.

Some day science may have the existence of mankind in power, and the human race can commit suicide by blowing up the world.

My religion encompasses all religions. I believe in God, I believe in the universe. I believe you are god, I believe I am god; I believe the earth is god and the universe is god. We’re all god.

I think it quite likely that we are the only civilization within several hundred light years; otherwise we would have heard radio waves.

Life is not a series of gig lamps symmetrically arranged; life is a luminous halo, a semi-transparent envelope surrounding us from the beginning of consciousness to the end.

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.

Look at the sky. We are not alone. The whole universe is friendly to us and conspires only to give the best to those who dream and work.

The animals of the world exist for their own reasons. They were not made for humans any more than black people were made for white, or women created for men.

The universe can take quite a while to deliver.

Let man live at a distance from God, and the universe remains neutral or hostile to him. But let man believe in God, and immediately all around him the elements, even the irksome, of the inevitable organize themselves into a friendly whole, ordered to the ultimate success of life.

The ‚I think‘ which Kant said must be able to accompany all my objects, is the ‚I breathe‘ which actually does accompany them.

We all dream. We dream vividly, depending on our nature. Our existence is beyond our explanation, whether we believe in God or we have religion or we’re atheist.

The hypothesis of matter’s being at first evenly spread through the heavens is, in my opinion, inconsistent with the hypothesis of innate gravity without a supernatural power to reconcile them, and therefore, it infers a deity.

I think music is one of the hero/sheroes of the African-American existence.

We’ve gotta become the Martians. I’m a Martian – I tell you to become Martians. And we’ve gotta go to Mars and civilize Mars and build a whole civilization on Mars and then move out, 300 years from now into the universe. And when we do that, we have a chance of living forever.

And if a person is religious, I think it’s good, it helps you a bit. But if you’re not, at least you can have the sense that there is a condition inside you which looks at the stars with amazement and awe.

What is the Tao Te Ching? Five hundred years before the birth of Jesus, a God-realized being named Lao-tzu in ancient China dictated 81 verses which are regarded by many as the ultimate commentary on the nature of existence.

Love is an adventure and a conquest. It survives and develops, like the universe itself, only by perpetual discovery.

The problem of evil, that is to say the reconciling of our failures, even the purely physical ones, with creative goodness and creative power, will always remain one of the most disturbing mysteries of the universe for both our hearts and our minds.

What was God doing before the divine creation?

Life is our dictionary.

Modern science says: ‚The sun is the past, the earth is the present, the moon is the future.‘ From an incandescent mass we have originated, and into a frozen mass we shall turn. Merciless is the law of nature, and rapidly and irresistibly we are drawn to our doom.

Up until the 1920s, everyone thought the universe was essentially static and unchanging in time.

The universe as we know it is a joint product of the observer and the observed.

Every living being is an engine geared to the wheelwork of the universe. Though seemingly affected only by its immediate surrounding, the sphere of external influence extends to infinite distance.

It’s possible – you can never know – that the universe exists only for me. If so, it’s sure going well for me, I must admit.

The ultimate connection is when you are connected to the creator of the universe.

Technology is destructive only in the hands of people who do not realize that they are one and the same process as the universe.

Protecting the rights of even the least individual among us is basically the only excuse the government has for even existing.

Between us and heaven or hell there is only life, which is the frailest thing in the world.

Existence really is an imperfect tense that never becomes a present.

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

Whatever universe a professor believes in must at any rate be a universe that lends itself to lengthy discourse. A universe definable in two sentences is something for which the professorial intellect has no use. No faith in anything of that cheap kind!

If it’s true that our species is alone in the universe, then I’d have to say the universe aimed rather low and settled for very little.

The Milky Way is nothing else but a mass of innumerable stars planted together in clusters.

Science sent the Hubble telescope out into space, so it could capture light and the absence thereof, from the very beginning of time. And the telescope really did that. So now we know that there was once absolutely nothing, such a perfect nothing that there wasn’t even nothing or once.

When I have a terrible need of – shall I say the word – religion. Then I go out and paint the stars.

The irrationality of a thing is no argument against its existence, rather a condition of it.

Man is unable to see himself entirely unrelated to mankind, neither is he able to see mankind unrelated to life, nor life unrelated to the universe.

A sense of the universe, a sense of the all, the nostalgia which seizes us when confronted by nature, beauty, music – these seem to be an expectation and awareness of a Great Presence.

Our virtues and our failings are inseparable, like force and matter. When they separate, man is no more.

There is no chance and anarchy in the universe. All is system and gradation. Every god is there sitting in his sphere.

We must conceive of this whole universe as one commonwealth of which both gods and men are members.

Today, all physicists know from studying Einstein and Bohr that sometimes an idea which looks completely paradoxical at first, if analyzed to completion in all detail and in experimental situations, may, in fact, not be paradoxical.

So long as the universe had a beginning, we could suppose it had a creator. But if the universe is really completely self-contained, having no boundary or edge, it would have neither beginning nor end: it would simply be. What place, then, for a creator?

Don’t think you are going to conceal thoughts by concealing evidence that they ever existed.

If we had a keen vision of all that is ordinary in human life, it would be like hearing the grass grow or the squirrel’s heart beat, and we should die of that roar which is the other side of silence.

Atoms are very special: they like certain particular partners, certain particular directions, and so on. It is the job of physics to analyze why each one wants what it wants.

Man is an exception, whatever else he is. If he is not the image of God, then he is a disease of the dust. If it is not true that a divine being fell, then we can only say that one of the animals went entirely off its head.

Relationships are like traffic lights. And I just have this theory that I can only exist in a relationship if it’s a green light.

The proper function of man is to live, not to exist. I shall not waste my days in trying to prolong them. I shall use my time.
