Stephen Hawking Quotes

Are we alone? Many, many people on planet Earth want to know. We are on the cusp of being able to answer that question... because of the investments we're making in space technology.

The total number of people that do a job that has the same description as mine in the entire world is fewer than 10. There's a lot of effort looking for life in space - that's a lot of what NASA does, but they're not necessarily looking for the kind of life that can hold up its side of a conversation.

We're all interested in life outside of Earth. We all have a fascination with what's out there because we don't really know.

Space exploration is a force of nature unto itself that no other force in society can rival.

I've always been interested in space and the idea of exploration in that area since I was a child growing up through the '60s.

Discovering traces of life on Mars would be of tremendous scientific significance: The first time that any signs of extraterrestrial life had ever been detected. Many people would also find it heartening to learn that we're not entirely alone in this vast, cold cosmos.

With 'Extinction Machine,' I wanted to start some conversations about whether we're alone in the universe and what that might mean.

As a species, we've always been discoverers and adventurers, and space and the deep ocean are some of the last frontiers.

Space and exploration are also related to inspiration.

Mankind is led into the darkness beyond our world by the inspiration of discovery and the longing to understand. Our journey into space will go on.

America's love affair with traveling into outer space is deeply entrenched.

Looking down the road, space exploration and the benefits it yields - in medicine and information technology - should not be overlooked.

The space shuttle was designed, at least in part, to broaden our knowledge of the universe. To scientists, the vehicle was a tool; to engineers, it was their creation.

NASA is an utterly fascinating place, and the fact that the buildings look so anonymous almost makes it more fascinating. You walk by a generic office-park-looking building, and you have no idea what's going on inside.

We need a space program because we need explorers. Its in our souls.

Science fiction is filled with Martians and space travel to other planets, and things like that.

I believe that there may be intelligent life on other planets.

I do believe there is life in outer space. Mathematically, there has to be, and if you believe as I do that there is a creator of the universe, then how can we be so arrogant to believe he created life here and nowhere else?

It doesn't matter how much faith you have or don't have. I just don't buy the idea that we're alone. There's got to be some form of life out there.

We must still think of ourselves as pioneers to understand the importance of space.

This planet seems to be in such sorry shape. And I can't ever think about the rest of the universe without coming back home and thinking what the implications for life here would be if we were to really have some definitive proof of extraterrestrial life.

We can never prove that we're alone in the universe. But the Allen Telescope Array could prove that we're not.

With the Hubble telescope and all the other things that are out there, I believe something would have come through. Today, I really believe we are unique.

When I grew up, I saw the moon landing, and I was fascinated watching them as a child, and that's what really turned me onto space and science fiction, and I started watching things like 'Lost In Space,' and that led me to 'Star Trek,' which was a major influence on my life.

There is just one thing I can promise you about the outer-space program - your tax-dollar will go further.
