Neil deGrasse Tyson Quotes

The human race shouldn't have all its eggs in one basket, or on one planet. Let's hope we can avoid dropping the basket until we have spread the load.

Life on Earth is at the ever-increasing risk of being wiped out by a disaster, such as sudden global warming, nuclear war, a genetically engineered virus or other dangers. I think the human race has no future if it doesn't go into space. I therefore want to encourage public interest in space.

We need to take command of the solar system to gain that wealth, and to escape the sea of paper our government is becoming, and for some decent chance of stopping a Dinosaur Killer asteroid.

I don't want people to spend their nights worrying about getting hit by asteroids. But I do want them to encourage their political leaders to invest in the insurance, which will allow us to prevent it from happening.

The single simplest reason why human space flight is necessary is this, stated as plainly as possible: keeping all your breeding pairs in one place is a retarded way to run a species.

It's really incumbent upon us as life's agents to extend life to another planet. I think that being a multi-planet species will significantly increase the richness and scope of the human experience.

I don't think the human race will survive the next thousand years, unless we spread into space. There are too many accidents that can befall life on a single planet. But I'm an optimist. We will reach out to the stars.

Space travel leading to skylife is vital to human survival, because the question is not whether we will be hit by an asteroid, but when. A planetary culture that does not develop spacefaring is courting suicide. All our history, all our social progress and growing insight will be for nothing if we perish. No risk of this kind, however small it might be argued to be, is worth taking, and no cost to prevent it is too great. No level of risk is acceptable when it comes to all or nothing survival.

Some asteroids have us in their sights. Be nice to sort of go near them and find out what they're made of, possibly tag their ears so they're always broadcasting to us their location. In case one of their trajectories head straight for us, we'll know well in advance to do something about it.

We have the capability - physically, technically - to protect the Earth from asteroid impacts. We are now able to very slightly and subtly reshape the solar system in order to enhance human survival.

From my perspective, it's really risk management to ensure that humans have the ability to go somewhere else in case there were to be some huge disaster on Earth.

The future of humanity is going to bifurcate in two directions: Either it's going to become multiplanetary, or it's going to remain confined to one planet and eventually there's going to be an extinction event.

I believe that the only way that the human race is gonna survive is to start colonizing space and setting up colonies on the moon, and then space stations.

In the long term, it is desirable that the human race, faced with the prospect of extinction on Earth, should prepare an escape route for itself to another inhabitable planet.

Here on Earth, we're exposed to asteroids hitting the Earth, eventual changes in the Sun, changes in the Earth's climate, things we're doing to the Earth's climate. If we want to survive, we need to become a multi-planet species. That's further down the road, but the first wave is going to be the explorers.

I believe that the long-term future of the human race must be space and that it represents an important life insurance for our future survival, as it could prevent the disappearance of humanity by colonizing other planets.

So we say, oh, my goodness; we think we've found another Earth-like planet. We will start trying to figure out how to get there. And I have this strong belief that whatever we think we can do, whatever we can dream, we can do.

There are people that tell you we gotta colonize Mars in the next 50 years if we're to survive as a human race. It's absolute stupidity. All it does is scare people - particularly young, impressionable minds who already think there isn't gonna be a planet in 30 years. Now they're thinking, since there isn't gonna be a planet, "If we don't get to Mars in 30 years, I'm gonna die."

As long as we are a single-planet species, we are vulnerable to extinction by a planetwide catastrophe, natural or self-induced. Once we become a multiplanet species, our chances to live long and prosper will take a huge leap skyward.

Remember this: once the human race is established on more than one planet and especially, in more than one solar system, there is no way now imaginable to kill off the human race.

To our knowledge, life exists on only one planet, Earth. If something bad happens, it's gone. I think we should establish life on another planet-Mars in particular-but we 're not making very good progress. SpaceX is intended to make that happen.

In my considered opinion, the profit to be made by permanent settlement in space is nothing less than the survival of industrial civilization, and therefore the survival of nearly the entire human race, along with such amenities as peace, freedom, enough to eat, and the chance to reach a high age in good health.

Let me end with an explanation of why I believe the move into space to be a human imperative. It seems to me obvious in too many ways to need listing that we cannot much longer depend upon our planet's relatively fragile ecosystem to handle the realities of the human tomorrow. Unless we turn human growth and energy toward the challenges and promises of space, our only other choice may be the awful risk, currently demonstrable, of stumbling into a cycle of fratricide and regression which could end all chances of our evolving further or of even surviving.

No one has any idea what's going to happen. Not even Elon Musk. That's why he's building those rockets. He wants a 'Plan B' on another world.

To think of these stars that you see overhead at night, these vast worlds which we can never reach. I would annex the planets if I could; I often think of that. It makes me sad to see them so clear and yet so far.
