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

In a way, the whole tangible universe itself is a vast residue, a skeleton of countless lives that have germinated in it and have left it, leaving behind them only a trifling, infinitesimal part of their riches.

I would like to fly in space. Absolutely. That would be cool. I used to just do personally risky things, but now I’ve got kids and responsibilities, so I can’t be my own test pilot. That wouldn’t be a good idea. But I definitely want to fly as soon as it’s a sensible thing to do.

Philosophically considered, the universe is composed of Nature and the Soul. Strictly speaking, therefore, all that is separate from us, all which Philosophy distinguishes as the ‚Not Me,‘ that is, both nature and art, all other men and my own body, must be ranked under this name, ‚Nature.‘

All variety of created objects which represent order and life in the universe could happen only by the willful reasoning of its original Creator, whom I call the ‚Lord God.‘

SpaceX has the potential of saving the U.S. government $1 billion a year. We are opposed to creating an entrenched monopoly with no realistic means for anyone to compete.

It is the stars, The stars above us, govern our conditions.

I’m trying to construct a world that maximises the probability that SpaceX continues its mission without me.

The Tao that can be told is not the eternal Tao; the name that can be named is not the eternal name. The Nameless is the origin of Heaven and Earth; the Named is the mother of all things.

The strategic objective of New Shepard is to practice, and a lot of the subcomponents of New Shepard actually get directly reused on the second stage of New Glenn.

Everything in the universe has a purpose. Indeed, the invisible intelligence that flows through everything in a purposeful fashion is also flowing through you.

A nation or civilization that continues to produce soft-minded men purchases its own spiritual death on the installment plan.

The boundary between space and the earth is purely arbitrary. And I’ll probably always be interested in this planet – it’s my favorite.

We are an impossibility in an impossible universe.

Iraq is no diversion. It is a place where civilization is taking a decisive stand against chaos and terror, we must not waver.

We get the exciting result that the total energy of the universe is zero. Why this should be so is one of the great mysteries – and therefore one of the important questions of physics. After all, what would be the use of studying physics if the mysteries were not the most important things to investigate?

Music is a moral law. It gives soul to the universe, wings to the mind, flight to the imagination, and charm and gaiety to life and to everything.

In a very real sense, it will not be one man going to the moon it will be an entire nation. For all of us must work to put him there.

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

Our posturings, our imagined self-importance, the delusion that we have some privileged position in the universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark.

The moral arc of the universe bends at the elbow of justice.

Even these stars, which seem so numerous, are as sand, as dust – or less than dust – in the enormity of the space in which there is nothing.

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

In the divine milieu, all the elements of the universe touch each other by that which is most inward and ultimate in them. There they concentrate, little by little, all that is purest and most attractive in them without loss and without danger of subsequent corruption.

I really believe in the philosophy that you create your own universe. I’m just trying to create a good one for myself.

If you wish to make an apple pie from scratch, you must first invent the universe.

Nature teaches us that tens of billions of light years may have passed, and life in all of its expressions has always been subjected to an incredible combination of matter and radiation.

My vision is for a fully reusable rocket transport system between Earth and Mars that is able to re-fuel on Mars – this is very important – so you don’t have to carry the return fuel when you go there.

If a nation expects to be ignorant and free, in a state of civilization, it expects what never was and never will be.

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.

To be more childlike, you don’t have to give up being an adult. The fully integrated person is capable of being both an adult and a child simultaneously. Recapture the childlike feelings of wide-eyed excitement, spontaneous appreciation, cutting loose, and being full of awe and wonder at this magnificent universe.

We only have to look at ourselves to see how intelligent life might develop into something we wouldn’t want to meet.

It’s time for the human race to enter the solar system.

I believe nothing happens by mistake. You know, the universe has a divine plan. That sounds dramatic.

We will build new ships to carry man forward into the universe, to gain a new foothold on the moon and to prepare for new journeys to the worlds beyond our own.

Helped are those who create anything at all, for they shall relive the thrill of their own conception and realize a partnership in the creation of the Universe that keeps them responsible and cheerful.

It suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the planet Earth. I didn’t feel like a giant. I felt very, very small.

I believe everyone should have a broad picture of how the universe operates and our place in it. It is a basic human desire. And it also puts our worries in perspective.

The universe is transformation: life is opinion.

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.

One might be led to suspect that there were all sorts of things going on in the universe which he or she did not thoroughly understand.

Before 1915, space and time were thought of as a fixed arena in which events took place, but which was not affected by what happened in it. Space and time are now dynamic quantities… space and time not only affect but are also affected by everything that happens in the universe.

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!

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

There was something undifferentiated and yet complete, which existed before Heaven and Earth. Soundless and formless, it depends on nothing and does not change. It operates everywhere and is free from danger. It may be considered the mother of the universe. I do not know its name; I call it Tao.

The ultimate tendency of civilization is towards barbarism.

That deep emotional conviction of the presence of a superior reasoning power, which is revealed in the incomprehensible universe, forms my idea of God.

We need to know what the resources of the moon are. We have great evidence now because of different kinds of radar and spectroscopic analysis that people have been able to do. But we really do need to go visit there, and we can do that with a robot craft without any problem.

While physics and mathematics may tell us how the universe began, they are not much use in predicting human behavior because there are far too many equations to solve. I’m no better than anyone else at understanding what makes people tick, particularly women.

To my mathematical brain, the numbers alone make thinking about aliens perfectly rational. The real challenge is to work out what aliens might actually be like.

The important achievement of Apollo was demonstrating that humanity is not forever chained to this planet and our visions go rather further than that and our opportunities are unlimited.

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.

Here men from the planet Earth first set foot upon the Moon. July 1969 AD. We came in peace for all mankind.

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

Each new generation born is in effect an invasion of civilization by little barbarians, who must be civilized before it is too late.

Millions of people were inspired by the Apollo Program. I was five years old when I watched Apollo 11 unfold on television, and without any doubt it was a big contributor to my passions for science, engineering, and exploration.

The universe seems neither benign nor hostile, merely indifferent.

When humor goes, there goes civilization.

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.

I believe the universe is governed by the laws of science. The laws may have been decreed by God, but God does not intervene to break the laws.

Science fiction, to me, has not only things that wouldn’t happen, but other planets.
