I'm

Oh Thank you. I'm Astronomycast, Episode 778, Dyson Swarms.

Welcome to AstronomyCaster, our weekly facts-based journey through the cosmos, where we help you understand not only what we know, but how we know what we know. I'm Fraser Kane. I'm the publisher of the Universe today with me, as always, is Dr. Pamela, a senior scientist for the Planetary Science Institute and the Director of Cosmo Quest. Hey, Pamela, how you doing? I'm doing well following the holidays. It is definitely a three coffee Monday.

No, the forbidden third coffee. No, you do not drink the forbidden third coffee.

It is here. It will be drink during this episode.

Yeah, yeah. I, every now and then, like for me,

two coffee, right? One coffee when I get up, one coffee after I've sort of done a bunch of

important work and deserve a reward. Exactly. A third coffee, if the second coffee just like

didn't do its desire to job, or I'm just feeling like I want to continue the sort of the habit, the ritual.

But my wife gives me this sort of stern look. And she goes, that's your third coffee, isn't it?

And you, you know, you're you're to and fro from the bathroom. You are having trouble getting

to sleep at night. You are feeling a little jittery,

you regret it every single time. And I'm like, shut up and let me drink my coffee.

There will be no regrets. I refuse to ever regret coffee, except for Turkish coffee,

that often at least to regret. Apparently Apparently the new research, which we can shortly

ignore, is that having a mix between coffee and tea actually gives you the greatest health

outcome. So now Carla has wisely said, hey, I'll make you some tea drink tea. And like, fancy

tea, boulong this and much of that. And so she will go, like, I'll make some tea. And so I'll have a glass, a cup of the tea. And then that, that hits all the same spots. So, so that's, that's the solution. Instead of the dreaded third coffee, up your tea game. I need easier to clean tea filters. Right. That's a personal problem. Yeah. Yeah. She's got like a metal one that she puts in her

her teapot. It works really well. So, um, right, let's do our job. Freeman Dyson asked a fascinating

question. What would it look like if a civilization was using all the energy coming from the star?

And what form would this take? This introduced the

concept of a Dyson sphere or more realistically a Dyson swarm surrounding a star. But if you're
