I think the discovery of supersymmetric partners for the known particles would revolutionize our understanding of the universe.

Philosophy is written in this grand book, the universe, which stands continually open to our gaze. But the book cannot be understood unless one first learns to comprehend the language and read the letters in which it is composed.

Sometimes, when I see my granddaughters make small discoveries of their own, I wish I were a child.

Before we understand science, it is natural to believe that God created the universe.

Against eternal injustice, man must assert justice, and to protest against the universe of grief, he must create happiness.

It is a profound and necessary truth that the deep things in science are not found because they are useful: they are found because it was possible to find them.

Classic economic theory, based as it is on an inadequate theory of human motivation, could be revolutionized by accepting the reality of higher human needs, including the impulse to self actualization and the love for the highest values.

The myths underlying our culture and underlying our common sense have not taught us to feel identical with the universe, but only parts of it, only in it, only confronting it – aliens.

Everything starts somewhere, although many physicists disagree.

Gravitation is, so far, not understandable in terms of other phenomena.

If a projectile were deprived of the force of gravity, it would not be deflected toward the earth but would go off in a straight line into the heavens and do so with uniform motion, provided that the resistance of the air were removed.

It is indeed a matter of great difficulty to discover, and effectually to distinguish, the true motions of particular bodies from the apparent because the parts of that immovable space, in which those motions are performed, do by no means come under the observation of our senses.

I tend to approach things from a physics framework. And physics teaches you to reason from first principles rather than by analogy.

It is now quite lawful for a Catholic woman to avoid pregnancy by a resort to mathematics, though she is still forbidden to resort to physics or chemistry.

In known history, nobody has had such capacity for altering the universe than the people of the United States of America. And nobody has gone about it in such an aggressive way.

Time can behave like another direction in space under extreme conditions.

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.

It is generally recognised that women are better than men at languages, personal relations and multi-tasking, but less good at map-reading and spatial awareness. It is therefore not unreasonable to suppose that women might be less good at mathematics and physics.

The missing link in cosmology is the nature of dark matter and dark energy.

If the stars should appear but one night every thousand years how man would marvel and stare.

What goes up must come down.

I am not the first Buddha who came upon Earth, nor shall I be the last. In due time, another Buddha will arise in the world – a Holy One, a supremely enlightened One, endowed with wisdom in conduct, auspicious, knowing the universe, an incomparable leader of men, a master of angels and mortals.

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.

It now appears that the way the universe began can indeed be determined, using imaginary time.

My desire was not to pass any island without taking possession, so that, one having been taken, the same may be said of all.

The universe is very large, and its boundaries are not known very well, but it is still possible to define some kind of a radius to be associated with it.

There are trees of a thousand sorts, and all have their several fruits; and I feel the most unhappy man in the world not to know them, for I am well assured that they are all valuable. I bring home specimens of them, and also of the land.

Science predicts that many different kinds of universe will be spontaneously created out of nothing. It is a matter of chance which we are in.

Not all those who wander are lost.

When we contemplate the whole globe as one great dewdrop, striped and dotted with continents and islands, flying through space with other stars all singing and shining together as one, the whole universe appears as an infinite storm of beauty.

Physics has a history of synthesizing many phenomena into a few theories.

To every action there is always opposed an equal reaction.

OK, so what’s the speed of dark?

What is a weed? A plant whose virtues have never been discovered.

To the mind that is still, the whole universe surrenders.

We’re a blip in the existence of the universe, and we’re constantly trying to pull each other down. Not doing things to help each other.

The clearest way into the Universe is through a forest wilderness.

Facts which at first seem improbable will, even on scant explanation, drop the cloak which has hidden them and stand forth in naked and simple beauty.

Every day I try to be in communication with the universe in an unconscious way.

Astronomy compels the soul to look upwards and leads us from this world to another.

I went to Princeton specifically to study physics.

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.

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

Scientists have become the bearers of the torch of discovery in our quest for knowledge.

There is nothing bigger or older than the universe.

The whole object of travel is not to set foot on foreign land; it is at last to set foot on one’s own country as a foreign land.

It was one of those evenings when men feel that truth, goodness and beauty are one. In the morning, when they commit their discovery to paper, when others read it written there, it looks wholly ridiculous.

That the divided but contiguous particles of bodies may be separated from one another is a matter of observation; and, in the particles that remain undivided, our minds are able to distinguish yet lesser parts, as is mathematically demonstrated.

The universe is not required to be in perfect harmony with human ambition.

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.

My first popular book, ‚A Brief History of Time,‘ aroused a great deal of interest, but many found it difficult to understand.

There isn’t any formula or method. You learn to love by loving – by paying attention and doing what one thereby discovers has to be done.

My goal is simple. It is a complete understanding of the universe, why it is as it is and why it exists at all.

Time discovers truth.

We are always paid for our suspicion by finding what we suspect.

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.

Space is big. You just won’t believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it’s a long way down the road to the drug store, but that’s just peanuts to space.

The first amazing fact about gravitation is that the ratio of inertial mass to gravitational mass is constant wherever we have checked it. The second amazing thing about gravitation is how weak it is.

There are no black holes in the sense of regimes from which light can’t escape to infinity.

The most remarkable discovery in all of astronomy is that the stars are made of atoms of the same kind as those on the earth.

We call first truths those we discover after all the others.
