Some people try to tell me that science will never answer the big questions we have in life. To them I say: baloney! The real problem is your questions aren't big enough.

When you're dealing with the universe, ignorance can be deadly.

I'm tired of ignorance held up as inspiration, where vicious anti-intellectualism is considered a positive trait, and where uninformed opinion is displayed as fact.

Our solar system is fantastically bizarre. There are worlds with features we never imagined. Storms larger than planets, moons with under-surface oceans, lakes of methane, worldlets that swap places...and that's just at Saturn.

If a little kid ever asks you just why the sky is blue, you look him or her right in the eye and say, 'It's because of quantum effects involving Rayleigh scattering combined with a lack of violet photon receptors in our retinae.'

Sixty-five million years ago the dinosaurs had a bad day.

Just like people, stars can be important without being terribly bright.
