Service to society is the rent we pay for living on this planet.

Man is the animal that intends to shoot himself out into interplanetary space, after having given up on the problem of an efficient way to get himself five miles to work and back each day.

I used to cry on planes. I don't anymore. It probably took almost a hundred agonizing flights to get there. Now, when I take off, a smile quivers on the corner of my lips.

Good Deeds Day is based on a simple idea that every person can do a good deed for the benefit of others and the planet. Even a smile that brightens someone else's day is a good deed. I initiated Good Deeds Day to spread the message that everyone can give of themselves, according to their heart's desire.

We're looking at Earth science, observing our planet. Also space science, looking at the ozone in the atmosphere around our Earth. Also looking at life science. And on a human level, using ourselves as test subjects.

Science fiction, to me, has not only things that wouldn't happen, but other planets.

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

If you go to planetary science meetings and hear technical talks on Pluto, you will hear experts calling it a planet every day.

What has become clear from the science is that we cannot burn all of the fossil fuels without creating a very different planet.

It will free man from the remaining chains, the chains of gravity which still tie him to this planet.

Mars is the only place in the solar system where it's possible for life to become multi-planetarian.

When I investigate and when I discover that the forces of the heavens and the planets are within ourselves, then truly I seem to be living among the gods.

I was really sad after 'The Avengers' when I realized I was not going to have a part in 'Thor 2' or 'Captain America: The Winter Soldier.' But I'm not arguing with my fantastic plane and my really cool car.

You know what I have noticed? And this is really sad. Flying first class is less scary than flying coach. They speak to you and they're so nice to you and they want to help you and they know you want a drink before the plane takes off. And they bring it to you without asking. If you're sitting in coach and hoping for a drink, good luck.

I think people get a sense of possibility when they're on a plane, even romantic possibility, wondering if the perfect person is going to sit down next to them or something.

I did send a girl a plane ticket asking her for a visit, I guess that's quite romantic.

You cannot look up at the night sky on the Planet Earth and not wonder what it's like to be up there amongst the stars. And I always look up at the moon and see it as the single most romantic place within the cosmos.

Perhaps I seek certain utopian things, space for human honour and respect, landscapes not yet offended, planets that do not exist yet, dreamed landscapes.

No white group has founded a major religion on this planet. The major religious were started in the Orient and the Middle East, not in Greece and Rome. I always knew you racists didn't have a prayer.

I like to think of religion as languages, our religion is very cultural, it has a lot to do with where we are born on this planet, it can really impact our religious beliefs.

I think flying planes into a building was a faith-based initiative. I think religion is a neurological disorder.

There was a time when someone would get on a plane and request to move their seat just because the person sitting next to them was of a different ethnicity or religion or nationality. But I don't think my generation wants that. That's how it used to be.

Science has killed religion. There's no hope for the future with seven billion of us on the planet, and the only thing you can do is to laugh in the face of it all.

Gravity may put the planets into motion, but without the divine Power, it could never put them into such a circulating motion as they have about the Sun; and therefore, for this as well as other reasons, I am compelled to ascribe the frame of this System to an intelligent Agent.
