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

I think we all change each other’s paths. I don’t know which law idea that is in physics, but I don’t think any of us can live without affecting one another.

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

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.

Science never makes things that do not have to do with what we feel, by which I mean what we want and what we fear.

There is neither spirit nor matter in the world. The stuff of the universe is spirit-matter. No other substance but this could have produced the human molecule.

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

You have a row of dominoes set up; you knock over the first one, and what will happen to the last one is that it will go over very quickly.

Working out another system to replace Newton’s laws took a long time because phenomena at the atomic level were quite strange. One had to lose one’s common sense in order to perceive what was happening at the atomic level.

Most of the fundamental ideas of science are essentially simple, and may, as a rule, be expressed in a language comprehensible to everyone.

I understood at a very early age that in nature, I felt everything I should feel in church but never did. Walking in the woods, I felt in touch with the universe and with the spirit of the universe.

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

I tell you the solemn truth, that the doctrine of the Trinity is not so difficult to accept for a working proposition as any one of the axioms of physics.

We’ve arranged a civilization in which most crucial elements profoundly depend on science and technology.

Art is the beautiful way of doing things. Science is the effective way of doing things. Business is the economic way of doing things.

Once you feel loved by the universe, you’re already accepted, and you’re not really concerned about offending people.

Chemistry, until my childhood, not that long ago, was regarded as a calculating device. Because you couldn’t reduce to physics. So it’s just some way of calculating the result of experiments. The Bohr atom was treated that way.

It is theoretically possible to warp spacetime itself, so you’re not actually moving faster than the speed of light, but it’s actually space that’s moving.

By staying focused on what I intend to create, by believing that the universe is all-providing, and by knowing that I’m worthy of the unlimited beneficence of the Source of being, I just keep attracting prosperity to me.

In every phenomenon the beginning remains always the most notable moment.

When we try to pick out anything by itself, we find it hitched to everything else in the universe.

The mineral world is a much more supple and mobile world than could be imagined by the science of the ancients. Vaguely analogous to the metamorphoses of living creatures, there occurs in the most solid rocks, as we now know, perpetual transformation of a mineral species.

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.

Science is what you know, philosophy is what you don’t know.

If we do discover a complete theory, it should be in time understandable in broad principle by everyone. Then we shall all, philosophers, scientists, and just ordinary people be able to take part in the discussion of why we and the universe exist.

The universe is change; our life is what our thoughts make it.

Rockets are cool. There’s no getting around that.

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

Space is almost infinite. As a matter of fact, we think it is infinite.

Politics is a science. You can demonstrate that you are right and that others are wrong.

In order for the United States to do the right things for the long term, it appears to be helpful for us to have the prospect of humiliation. Sputnik helped us fund good science – really good science: the semiconductor came out of it.

Science in the modern world has many uses; its chief use, however, is to provide long words to cover the errors of the rich.

The most obvious characteristic of science is its application: the fact that, as a consequence of science, one has a power to do things. And the effect this power has had need hardly be mentioned. The whole industrial revolution would almost have been impossible without the development of science.

Science is a beautiful gift to humanity; we should not distort it.

What goes up must come down.

If you are in a spaceship that is traveling at the speed of light, and you turn on the headlights, does anything happen?

M-theory is the unified theory Einstein was hoping to find.

Europe is so well gardened that it resembles a work of art, a scientific theory, a neat metaphysical system. Man has re-created Europe in his own image.

I like mathematics because it is not human and has nothing particular to do with this planet or with the whole accidental universe – because, like Spinoza’s God, it won’t love us in return.

To our critical eyes, the threads of which the past is woven are, by nature, endless and indivisible. Scientifically speaking, we cannot grasp the absolute beginning of anything: everything extends backwards to be prolonged by something else.

Before I lost my voice, it was slurred, so only those close to me could understand, but with the computer voice, I found I could give popular lectures. I enjoy communicating science. It is important that the public understands basic science, if they are not to leave vital decisions to others.

Is evolution a theory, a system, or an hypothesis? It is much more: it is a general condition to which all theories, all hypotheses, all systems must bow and which they must satisfy henceforward if they are to be thinkable and true.

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

The human race may be the only intelligent beings in the galaxy.

Everything in Nature contains all the powers of Nature. Everything is made of one hidden stuff.

To the dumb question, ‚Why me?‘ the cosmos barely bothers to return the reply, ‚Why not?‘

If you understand the universe, you control it, in a way.

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

The grand aim of all science is to cover the greatest number of empirical facts by logical deduction from the smallest number of hypotheses or axioms.

OK, so what’s the speed of dark?

I had a project for my life which involved 10 years of wandering, then some years of medical studies and, if any time was left, the great adventure of physics.

The man of science is a poor philosopher.

An object in motion tends to remain in motion along a straight line unless acted upon by an outside force.

The observer, when he seems to himself to be observing a stone, is really, if physics is to be believed, observing the effects of the stone upon himself.

Baseball is a universe as large as life itself, and therefore all things in life, whether good or bad, whether tragic or comic, fall within its domain.

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

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.

All are but parts of one stupendous whole, Whose body Nature is, and God the soul.

No one undertakes research in physics with the intention of winning a prize. It is the joy of discovering something no one knew before.

One of the first signs of the beginning of understanding is the wish to die.

We are the representatives of the cosmos; we are an example of what hydrogen atoms can do, given 15 billion years of cosmic evolution.
