A Quote by Stephen Hawking

"Sooner or later disasters such as an asteroid collision or a nuclear war could wipe us all out, But once we spread out into space and establish independent colonies, our future should be safe."

We could not wipe ourselves out with a nuclear war. I do not want so sound too positive. It would be a catastrophe, but it would not be a final one. We are not powerful enough for that. An asteroid could be that powerful. That is why we need to do our homework.

Rusty Schweickart

If we can avoid disaster for the next two centuries, our species should be safe as we spread into space. If we are the only intellegent beings in the galaxy we should make sure we survive and continue. . . . Our only chance of long-term survival is not to remain inward looking on planet Earth but to spread out into space. We have made remarkable progress in the last hundred years. But if we want to continue beyond the next hundred years, our future is in space.

Stephen Hawking

Sooner or later the space program will need to save us by detecting and deflecting an incoming asteroid.

Nathan Myhrvold

An asteroid or a supervolcano could certainly destroy us, but we also face risks the dinosaurs never saw: An engineered virus, nuclear war, inadvertent creation of a micro black hole, or some as-yet-unknown technology could spell the end of us.

Elon Musk

The future is about wings and wheels and new forms of space transportation, along with our deep-space ambition to set foot on another world in our solar system: Mars. I firmly believe we will establish permanence on that planet. And in reaching for that goal, we can cultivate commercial development of the moon, the asteroid belt, the Red Planet itself and beyond.

Buzz Aldrin

Sooner or later there will be a nuclear 9/11 [by Islamic terrorists] in an American city or that of a US ally... A terrorist nuclear attack against an American city could take many forms. A worst case scenario would be the detonation of a nuclear device within a city. Depending upon the size and sophistication of the weapon, it could kill hundreds of thousands or even millions of people.

David Krieger

We are creating the future. It is not determined. If we get our act together and solve our current problems, we could have a sustainable, abundant future. If we don't, we could wipe ourselves out. We are on the verge of doing it with our current politics. It is regressive, going back the other way.

Edgar Mitchell

Sooner or later, we will face a catastrophic threat from space. Of all the possible threats, only a gigantic asteroid hit can destroy the entire planet. If we prepare now, we better our odds of survival. The dinosaurs never knew what hit them.

Michio Kaku

Most estimates of the mortality risk posed by asteroid impacts put it at about the same risk as flying in a commercial airliner. However, you have to remember that this is like the entire human race riding the plane - it is one of the few risks that really could wipe us all out.

Nathan Myhrvold

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.

Stephen Hawking

If we could get out of this jam by giving up Malta and Gibraltar and some African colonies I would jump at it. But the only safe way is to convince Hitler that he cannot beat us.

Winston Churchill

Threats that could wipe out the bulk of life on earth abound. Planetary catastrophe could come in the form of a killer asteroid impact, the eruption of massive supervolcanoes, a nearby gamma ray burst that sterilizes the earth, or by human-driven environmental collapse.

Ramez Naam

Thoughts by a graveside are too dark and deep to be sustained for any length of time. Sooner or later the hurt mind turns to the sun for healing, and this is as it should be, for otherwise, what future could any of us hope for, but madness?

We have been led to believe that we have come a long way toward world nuclear disarmament. But that is not the case. Our government is not doing all that it could. We must urge our leaders to fulfill the obligations of the Nuclear Non-Proliferation Treaty. The United States must assume world leadership to end once and for all the threat of nuclear war. It is our moral responsibility.

Harrison Ford

Our intellectual powers are rather geared to master static relations and that our powers to visualize processes evolving in time are relatively poorly developed. For that reason we should do (as wise programmers aware of our limitations) our utmost to shorten the conceptual gap between the static program and the dynamic process, to make the correspondence between the program (spread out in text space) and the process (spread out in time) as trivial as possible.
