What is the premise of the episode and who is the guest?
Chuck, I don't think we can find a container to hold a full Akeem Olicheu.
No, I I don't even think a magnetic field would do it. Yeah. It's coming up. Boundless energy coming your way.
Delivered from the universe. Welcome to Star Talk. Your place in the universe where science and pop culture collide. Star Talk begins right now. This is StarTalk, Neil deGrasse Tyson, your personal astrophysicist. Chuck Nice right next to me. What's up, Neil? All right, man. How are you, buddy? Doing good? Doing good? Doing great. We've got cosmic queries today. Yes, we do. Inquiring minds want to know. Indeed. And in fact. It's on cosmology. Ooh. Ooh. It is the expertise of our guest. Third time on Star Talk? Yeah. I think so. That's right. Hakeem Ulyshee.
Thank you so much. And it is the fourth time. Fourth time. Oh, this is the fourth time. Oh, that's right. Because this Yeah, no, wait, four times Memoir, Cosmic Queries, both remote, and then finally. Yeah, it
kinda messes with the remote. Well, we got an astrophysicist, cosmologist, which is a subdivision of all astrophysicists who thinks about the origin, evolution, and fate. of the universe. Right. Plus, he's been practicing my open for this show. And I don't know if I should be happy about it or kick his ass later. Let me hear let me hear. Go. Let's see. This is Star Talk. You know, that's pretty good.
Not bad. That's yeah. You know. Yeah. Right now with uh three black eyes up here, I don't know who's who.
Wait a minute, wait a minute. I wanna get I wanna
get back to this kick your
ass comic. That's hilarious. Yeah. So you're host of the podcast Particles of Thought. I love that title. And it's a Nova podcast. It's a Nova podcast. PBS Nova, G B H out of Boston. Very good. Very nice. And CEO. How many people get to say it a CEO? Because if you're CEO, you demand. That's right. CEO of the Astronomical Society of the Pacific. Very nice. And I'm going to ask you About that in a minute. And you've also associated with NESA's IMAP satellite. Yes. Remind me what IMAP stands for. Interstellar mapping and
acceleration probe. Nice. Who's accelerating? The sun's magnetic fields both at the surface of the sun and interactions with the sun solar wind and particles trapped in the heliosphere. Uh-huh. Right? And those generate neutral atoms that come back into the solar system that get measured by IMAP.
Wow. Wow.
Yeah. Okay. All right.
And may I ask?
Why? And and if you worry about the sun, that doesn't sound very cosmological. So how does it how do you
stitch that together? Because I started out doing instrumentation and calculations, computational, and understanding plasmas really well. So it's kind of like I have this toolbox that I can travel from field to field with, right? So I've done proposal. Plasma is everywhere in the freaking universe. Plasma is everywhere in the freaking universe. Absolutely. Absolutely.
Oh my gosh. And tell people we're not talking about blood plasma. No kind of blasphemy. No. I forgot about that. I forgot about that. Yeah, yeah, yeah. Yeah, yeah, yeah. There's a whole other kind of thing is a different plasma. There's a whole other kind of plasma.
So this is when you take a gas, heat it even more, you break more bonds, right? And you break the solid to liquid bond, liquid to gas. Now, once you're a gas, you're just molecules or atoms, you start breaking those apart. So once you break apart electrons from atoms, you now have a plasma. Yeah.
electron soup. Basically. Yeah. Yeah. Yeah. And so so this gas will respond to magnetic fields. Right. You can do really cool things with it. Right. Including Feed a fusion reactor for the future of energy. Yeah.
And that's but that'd be the only way you would be able to hold the energy is in a magnetic field bottle, right? Not necessarily. No, really, but Really?
Enclose it in a metal and blast it, generating X-rays that create fusion. Oh, but that's not a I'm sorry. I was taking fusion. That's not a plasma. You're starting with a a little seed, right? But yeah, so if you're gonna confine a plasma, you're gonna do that with magnetic fields. Okay. Okay, okay, all right. Totally on the back.
