If you're going to lead a space frontier, it has to be government; it'll never be private enterprise. Because the space frontier is dangerous, and it's expensive, and it has unquantified risks. And under those conditions, you cannot establish a capital-market evaluation of that enterprise. You can't get investors.

The very nature of science is discoveries, and the best of those discoveries are the ones you don't expect.
-
I'm often asked by parents what advice can I give them to help get kids interested in science? And I have only one bit of advice. Get out of their way. Kids are born curious. Period.
-
I like to believe that science is becoming mainstream. It should have never been something that sort of geeky people do and no one else thinks about. Whether or not, it will always be what geeky people do. It should, as a minimum, be what everybody thinks about because science is all around us.

The only driver stronger than an economic argument to do something is the war argument, the I-don't-want-to-die argument.

Many academicians don't even own a television, much less watch one.
-
I never got into 'Star Wars.' Maybe because they made no attempt to portray real physics. At all.
-
Any astrophysicist does not feel small looking up at the universe; we feel large.
-
In all civilizations we've studied, all cultures that we know of across the Earth and across time have invested some kind of attempt to understanding where where, where they come from, and where they are going.
-
One of the things that fascinates me most is when people are so charmed by the universe that it becomes part of their artistic output.
-
I'm on a crusade to get movie directors to get their science right because, more often than they believe, the science is more extraordinary than anything they can invent.

When Kennedy said, 'Let's go to the moon,' we didn't yet have a vehicle that wouldn't kill you on launch. He said we'll land a man on the moon in eight years and bring him back. That was an audacious goal to put forth in front of the American people.

Space enthusiasts are the most susceptible demographic to delusion that I have ever seen.

No one wants to die, and no one wants to die poor. These are the two fundamental truths that transcend culture, they transcend politics, they transcend economic cycles.

If we find life out there, and it's not us, we will deem it not intelligent. But what may be equally as likely is that we find life that's vastly more intelligent than we are. If that's the case, we are putty in their hands.

All tweets are tasty. Any tweet anybody writes is tasty. So, I try to have each tweet not simply be informative, but have some outlook, some perspective that you might not otherwise had.
-
We have bred multiple generations of people who have not experienced knowing where you are the moment a news story broke, with that news story being great and grand and something that elevates society instead of diminishes it.

The Venus transit is not a spectacle the way a total solar eclipse is a spectacle.
-
The problem is that many people operate on the assumption that NASA should go to Congress every year with hat in hand and justify it every year. Well, I see it as the greatest economic driver that there ever was. Economic drivers don't need justification.
-
The universe is almost 14 billion years old, and, wow! Life had no problem starting here on Earth! I think it would be inexcusably egocentric of us to suggest that we're alone in the universe.

I know of no time in human history where ignorance was better than knowledge.

Halley shattered their monopoly, beating them at their own game. A game that no scientist had ever played before: Prophecy. -S01E03
-
Those who see the cosmic perspective as a depressing outlook, they really need to reassess how they think about the world. Because when I look up in the universe, I know I'm small but I'm also big. I'm big because I'm connected to the universe, and the universe is connected to me.

The first trillionaire in the world will be the person who mines asteroids.
