This is an IHeart podcast.

Hey guys, before I start a quick programming note, you'll probably notice my audio quality

I studied psychology and evolutionary biology, and today on the show,

How to Speak to Aliens!

We talk about the way that biological senses differ so vastly between humans, animals, and possibly aliens.

We use real-life biology to talk about how an alien encounter might actually go down

and the infinitesimally small chance that we ever bump into intelligent life.

Joining me today is friend of the show, particle physicist, host of the podcast Daniel and Kelly's

Extraordinary Universe and author of the new book, Do Aliens Speak Physics?

Daniel Whiteson, welcome!

Thank you very much.

I am a particle physicist and I believe in science, but I also irrationally believe we have

more than an infinitesimal chance to be visited by aliens.

How big of the chance? Like out of like one in five, one in ten?

I would say 17 infinitesimals, not just one infinitesimal. Okay. All right. Yeah. I mean,

that's, that's a pretty decent chance, I think. Yeah, I mean, so in your new book, you kind of talk about how you explore a lot of philosophical questions about aliens, and then you involve both like physics and also biology to talk about this, how it would be to try to essentially communicate with
