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.

If you look at our current technology level, something strange has to happen to civilisations, and I mean strange in a bad way. And it could be that there are a whole lot of dead, one-planet civilisations.

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.

Show me the person you honor, for I know better by that the kind of person you are. For you show me what your idea of humanity is.

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.

You could warm Mars up, over time, with greenhouse gases.

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

The mind is never satisfied with the objects immediately before it, but is always breaking away from the present moment, and losing itself in schemes of future felicity… The natural flights of the human mind are not from pleasure to pleasure, but from hope to hope.

Upon the creatures we have made, we are, ourselves, at last, dependent.

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.

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.

The Earth is a very small stage in a vast cosmic arena.

My future is righteousness.

Each generation goes further than the generation preceding it because it stands on the shoulders of that generation. You will have opportunities beyond anything we’ve ever known.

I’ve only written one science-fiction book: ‚Fahrenheit 451.‘ That book is a book based on real facts and my hatred of people who destroy books.

Dogmas are collective conceptual prisons. And the strange thing is that people love their prison cells because they give them a sense of security and a false sense of ‚I know.‘ Nothing has inflicted more suffering on humanity than its dogmas.

If you believe that feeling bad or worrying long enough will change a past or future event, then you are residing on another planet with a different reality system.

It’s much easier to be successful than it is to be relevant. The tricks won’t keep you relevant. Tricks might keep you popular for a while, but in all honesty, I don’t know how U2 will stay relevant. I know we’ve got a future. I know we can fill stadiums. And yet with every record, I think, ‚Is this it? Are we still relevant?‘

History is a relentless master. It has no present, only the past rushing into the future. To try to hold fast is to be swept aside.

Taking bold action on climate change simply makes good business sense. It’s also the right thing to do for people and the planet. Setting a net-zero GHG emissions target by 2050 will drive innovation, grow jobs, build prosperity, and secure a better world for what will soon be 9 billion people.

The most interesting biofuel efforts avoid using land that’s expensive and has high opportunity costs. They do this by getting onto other types of land, or taking advantage of byproducts that aren’t used in the food chain today, or by intercropping.

This generation of Americans has a rendezvous with destiny.

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

We are at the very beginning of time for the human race. It is not unreasonable that we grapple with problems. But there are tens of thousands of years in the future. Our responsibility is to do what we can, learn what we can, improve the solutions, and pass them on.

We should remember that there are nations which meet more than 30 to 60% of their power requirements through the nuclear power system.

The truth is you don’t know what is going to happen tomorrow. Life is a crazy ride, and nothing is guaranteed.

If anyone has a vested interest in space solar power, it would have to be me.

By the time we see that climate change is really bad, your ability to fix it is extremely limited… The carbon gets up there, but the heating effect is delayed. And then the effect of that heat on the species and ecosystem is delayed. That means that even when you turn virtuous, things are actually going to get worse for quite a while.

In less than a hundred years, we have found a new way to think of ourselves. From sitting at the center of the universe, we now find ourselves orbiting an average-sized sun, which is just one of millions of stars in our own Milky Way galaxy.

Perhaps travel cannot prevent bigotry, but by demonstrating that all peoples cry, laugh, eat, worry, and die, it can introduce the idea that if we try and understand each other, we may even become friends.

The universe is a big place, perhaps the biggest.

For me, when you are have people wondering what is next, what is coming out, you are on the right track.

It is true that SpaceX is partially a government contractor, but it would be unfair to say that SpaceX is entirely a government contractor.

It’s not as though we can keep burning coal in our power plants. Coal is a finite resource, too. We must find alternatives, and it’s a better idea to find alternatives sooner then wait until we run out of coal, and in the meantime, put God knows how many trillions of tons of CO2 that used to be buried underground into the atmosphere.

People will visit Mars, they will settle mars, and we should because it’s cool.

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.

When I die, I’m leaving my body to science fiction.

If the tongue had not been framed for articulation, man would still be a beast in the forest.

The universal utilization of water power and its long-distance transmission will supply every household with cheap power and will dispense with the necessity of burning fuel. The struggle for existence being lessened, there should be development along ideal rather than material lines.

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.

We are anthill men upon an anthill world.

If you prick us do we not bleed? If you tickle us do we not laugh? If you poison us do we not die? And if you wrong us shall we not revenge?

Our most basic common link is that we all inhabit this planet. We all breathe the same air. We all cherish our children’s future. And we are all mortal.

The centre of the system of the world is immovable.

A lot of dumb pictures have made a lot of money, but that doesn’t mean they’re going to be anything cinema students will revel over in the future.

If one by one we counted people out For the least sin, it wouldn’t take us long To get so we had no one left to live with. For to be social is to be forgiving.

The pace of progress on Mars depends upon the pace of progress of SpaceX.

Our daily deeds as ordinary South Africans must produce an actual South African reality that will reinforce humanity’s belief in justice, strengthen its confidence in the nobility of the human soul, and sustain all our hopes for a glorious life for all.

It is natural to want to have a future.

All great artists draw from the same resource: the human heart, which tells us that we are all more alike than we are unalike.

My biggest error? Something that is to happen yet.

Through space the universe encompasses and swallows me up like an atom; through thought I comprehend the world.

Humanity, you never had it to begin with.

I really do encourage other manufacturers to bring electric cars to market. It’s a good thing, and they need to bring it to market and keep iterating and improving and make better and better electric cars, and that’s what going to result in humanity achieving a sustainable transport future. I wish it was growing faster than it is.

We’re one of the only animals in the world that don’t really think of ourselves as animals, but we are animals, and we must respect our fellow animals.

The first question which the priest and the Levite asked was: ‚If I stop to help this man, what will happen to me?‘ But… the good Samaritan reversed the question: ‚If I do not stop to help this man, what will happen to him?‘

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

They say the universe is expanding. That should help with the traffic.

We cannot despair of humanity, since we ourselves are human beings.

Our existence is beyond our explanation, whether we believe in God or we have religion or we’re atheist. Our existence is beyond our understanding. No one has an answer.

There is nothing bigger or older than the universe.
