Welcome to science. You’re gonna like it here.

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.'

Pseudoscience is like a virus. At low levels, it's no big deal, but when it reaches a certain threshold it becomes sickening.

They say that even the brightest star won't shine forever. But in fact, the brightest star would live the shortest amount of time. Feel free to extract whatever life lesson you want from that.

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.

How do you convince someone they're not thinking clearly, when they're not thinking clearly? What we're actually saying is no magic, no afterlife, no higher moral authoritative father-figure, no security, and no happy ever after. This is a tough sell.

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