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

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

It’s time to commit to finding the answer, to search for life beyond Earth. Mankind has a deep need to explore, to learn, to know. We also happen to be sociable creatures. It is important for us to know if we are alone in the dark.

In the twenty-first century, the robot will take the place which slave labor occupied in ancient civilization.

I’m trying to get to Mars before everyone else.

Why should man’s first flight to the moon be a matter of national competition? Why should the United States and the Soviet Union, in preparing for such expeditions, become involved in immense duplications of research, construction and expenditure?

If we’re going to have any chance of sending stuff to other star systems, we need to be laser-focused on becoming a multi-planet civilisation.

There is more stupidity than hydrogen in the universe, and it has a longer shelf life.

In the beginning there was nothing, which exploded.

God may exist, but science can explain the universe without the need for a creator.

You accept that this civilisation could be abolished and life will begin later on after a few thousand years because that is something that has happened in the history of this planet. When you have peace in yourself and accept, then you are calm enough to do something, but if you are carried by despair there is no hope.

No people is wholly civilized where a distinction is drawn between stealing an office and stealing a purse.

NASA has been one of the most successful public investments in motivating students to do well and achieve all they can achieve. It’s sad that we are turning the programme in a direction where it will reduce the amount of motivation and stimulation it provides to young people.

Go on, prove me wrong. Destroy the fabric of the universe. See if I care.

It is far better to grasp the universe as it really is than to persist in delusion, however satisfying and reassuring.

You need to be in the position where it is the cost of the fuel that actually matters and not the cost of building the rocket in the first place.

The ultimate tendency of civilization is towards barbarism.

The gross heathenism of civilization has generally destroyed nature, and poetry, and all that is spiritual.

The world, we are told, was made especially for man – a presumption not supported by all the facts. A numerous class of men are painfully astonished whenever they find anything, living or dead, in all God’s universe, which they cannot eat or render in some way what they call useful to themselves.

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.

We’re working on New Glenn, which is our orbital vehicle, but we have in our mind’s eye an even bigger vehicle called New Armstrong.

Houston, Tranquillity Base here. The Eagle has landed.

We’ve persevered because of a belief we share with the Iraqi people – a belief that out of the ashes of war, a new beginning could be born in this cradle of civilization. Through this remarkable chapter in the history of the United States and Iraq, we have met our responsibility. Now, it’s time to turn the page.

It’s not going to do any good to land on Mars if we’re stupid.

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.

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

The revolutionary breakthrough will come with rockets that are fully and rapidly reusable. We will never conquer Mars unless we do that. It’ll be too expensive. The American colonies would never have been pioneered if the ships that crossed the ocean hadn’t been reusable.

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

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

The study and knowledge of the universe would somehow be lame and defective were no practical results to follow.

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.

Increased means and increased leisure are the two civilizers of man.

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.

You need to live in a dome initially, but over time you could terraform Mars to look like Earth and eventually walk around outside without anything on… So it’s a fixer-upper of a planet.

I feel very strongly that SpaceX would not have been able to get started, nor would we have made the progress that we have, without the help of NASA.

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.

Historically, the stuff of the universe goes on becoming concentrated into ever more organized forms of matter.

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.

If the battle for civilization comes down to the wimps versus the barbarians, the barbarians are going to win.

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

Even Hubble hasn’t found yet the end of this universe, and we don’t know that it has any end.

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

Odd how the creative power at once brings the whole universe to order.

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

The civilized man has built a coach, but has lost the use of his feet.

I think really, China, Chinese, I think they really have a long history of civilization, rich culture.

I have thought a sufficient measure of civilization is the influence of good women.

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

The development of civilization and industry in general has always shown itself so active in the destruction of forests that everything that has been done for their conservation and production is completely insignificant in comparison.

Look up at the stars and not down at your feet. Try to make sense of what you see, and wonder about what makes the universe exist. Be curious.

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.

The Apollo program certainly had no real commercial value. It was done for very different reasons and, I think, very good reasons for the time. It’s an extraordinary achievement of mankind, but it wasn’t sustainable.

I think God’s going to come down and pull civilization over for speeding.

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.‘

Words, words, words! They shut one off from the universe. Three quarters of the time one’s never in contact with things, only with the beastly words that stand for them.

Let’s pray that the human race never escapes from Earth to spread its iniquity elsewhere.

America has tossed its cap over the wall of space.

The sun, with all those planets revolving around it and dependent on it, can still ripen a bunch of grapes as if it had nothing else in the universe to do.

If you are not prepared to use force to defend civilization, then be prepared to accept barbarism.

This will never be a civilized country until we spend more money for books than we do for chewing gum.

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.
