Every day, I wake up and I say, 'Why... how... did I end up with 1.7 million Twitter followers?' It's freaky to me, every day, but that tells me that there's an appetite out there that had previously been underserved. There's an inner geek in us all, an inner bit of curiosity that people are discovering, and they like it.

The need to create a new taxonomy that isn't just applying to our own solar system will become so evident and apparent that something will come out of it. I'm sure of it, even if it's not tomorrow.
-
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.

Space enthusiasts are the most susceptible demographic to delusion that I have ever seen.
-
I've been a minimalist my whole life, even if you wouldn't know it from my office.
-
I know of no time in human history where ignorance was better than knowledge.
-
I can't tell you how many people say they were turned off from science because of a science teacher that completely sucked out all the inspiration and enthusiasm they had for the course.

The Venus transit is not a spectacle the way a total solar eclipse is a spectacle.
-
I don't comment on the physics errors of 'Star Wars,' all right. I just - you let that one go.

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 only becomes ordinary when the frontier is no longer being breached.
-
The only driver stronger than an economic argument to do something is the war argument, the I-don't-want-to-die argument.

There's a lot of memorization that goes on in school. You memorize vocabulary words and all these sorts of things.

Halley shattered their monopoly, beating them at their own game. A game that no scientist had ever played before: Prophecy. -S01E03

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.
-
I never got into 'Star Wars.' Maybe because they made no attempt to portray real physics. At all.
-
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.
-
There are thousands of asteroids whose orbit in the Solar System crosses that of Earth. And we have a little acronym for them - NEOs: near Earth objects. And our biggest goal is to try to catalogue them, so we know in advance if one is going to put us at risk.

All the nine-planet people out there: Get over it. There's eight.

Although I'm not actually embarrassed by this, I tend not to read books that have awesome movies made from them, regardless of how well or badly the movie represented the actual written story.

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.
