If I'm looking fit and I'm not, then I'm cheating.

I don't have an issue with what you do in the church but I'm going to be up in your face if you're going to knock on my science classroom and tell me I got to teach what you're teaching in your Sunday school. That's when we're going to fight... There's no tradition of scientists knocking down the Sunday school door, telling the preacher 'that might not necessarily be true.' That's never happened. There are no scientists picketing out front of churches. There's been this coexistence forever, so to have religious communities knocking down the science door, there's something wrong there.

This past year, we received our second Emmy nomination for Outstanding Informational Series. While we'd all like to win, I can say with utmost sincerity that it mattered more to me that we got noticed than whether or not we win.

Seventy percent of Earth's surface is water and over 99 percent is uninhabited, so you would expect nearly all impactors to hit either the ocean or desolate regions on Earth's surface. So why do movie meteors have such good aim?

You will never find scientists leading armies into battle. You just won’t. Especially not astrophysicists -we see the biggest picture there is. We understand how small we are in the cosmos. We understand how fragile and temporary our existence is here on Earth. We understand there are bigger problems we need to solve as a species than what God you pray to.

We hunger for significance, for signs that our personal existence is of special meaning to the universe. To that end, we’re all too eager to deceive ourselves and others, to discern a sacred image in a grilled cheese sandwich or find a divine warning in a comet

Let's invent a new tomorrow and then make it happen. Let's invent the city of tomorrow, the home of tomorrow, the transportation of tomorrow.
