Could we get sick if its dust gets in our face?

Scientific theory, model hypothesis, or law.

Do these words really mean anything or nah?

Whatever questions keep you up at night, Daniel and Kelly's answers will make it right.

Welcome to another listener questions episode on Daniel and Kelly's Extraordinary Universe.

We've done 22 of these.

Yeah. Hello, I'm Kelly Weiner-Smith.

I study parasites and space.

And all of these questions today have a bit of biology in them, so I'm pretty excited about it.

Hi, I'm Daniel.

I'm a particle physicist, and I'll admit there's a bit of biology in everything we do. Oh, yeah, but there's not physics in everything we do, so that's good news. Yes, there is. Yeah, no, of course there is. Physics is everything. Yeah, I guess I should have gone with chemistry, and then we could have bonded, even though we knew we were wrong. Exactly. then we could confirm each other's biases. Yep, yep. Anyway, I blew it. That's all right.

Moving on.

But today, bonded even though we knew we were wrong. Exactly. Then we could confirm each other's biases.

Yep, yep. Anyway, I blew it. That's all right. Moving on. But today we're not here to talk about my biases or about your biases. We're here to answer questions from you, from people out there

wondering how the universe works, trying to make sense of it, and scratching their heads a little bit.

And we try to help you scratch your heads for a slightly shorter amount of time.
