Welcome to StarTalk, your place in the universe where science and pop culture collide.

StarTalk begins right now.

This is StarTalk Radio, the Cosmic Queries part.

I'm Neil deGrasse Tyson, you're a host and I've got with me, in studio, Chuck Knies.

Hey, Neil, remind me, Twitter, you're Chuck Knies, nice comic.

That Chuck Knies comic, if I finally catch you up with how to find you on Twitter, there you

go.

Chuck, I brought you in because this is, as you know, this is the Cosmic Queries part of StarTalk.

Yes.

I sit here, I haven't seen any of these questions.

I've all filed in from Facebook, in Twitter, in Google Plus, in all of our media presence,

and this is the holiday edition.

So thanks for agreeing to do this.

It's always my pleasure to be here.

So I guess the point is not to stump me, although I could get stumped.

The point is just if I have knowledge to share through the filter of people's inquiries,

that's correct.

There we have it.

It's what inquiring minds want to know.

They got it.

And you got their names.

And their names go for it.
