What is the main topic discussed in this episode?
I love our stable of cosmologists.
Yeah.
This time, Sean Carroll. Yeah, Sean Carroll. I love him. Awesome. Because he's brilliant and we don't have to help out his explanations. Yeah. Because they're better than anything we come up with.
Yeah, and every time he's on, as well as Brian Cox or Jan Eleven or Blue or any of them, I realize I don't know Jack. Nothing. Coming up.
Welcome to StarTalk. Your place in the universe where science and pop culture collide. StarTalk begins right now. This is StarTalk Cosmic Queries Edition. Neil deGrasse Tyson, you're a personal astrophysicist. We got here, of course, Lord Chuck Nice.
Hey, what's happening, man?
You're locked and loaded there. I'm locked and loaded because we got queries, man. And they're not just queries about anything to anyone. No. They're queries on, like, cosmology. Yes. To one of our... cosmologist about town. Yes. One of our fave interviews. We've got Sean Carroll on the line.
How does Sean Carroll explain Hawking radiation and black holes?
Sean, how you doing, man?
Hey, how's it going? Lord Chuck, I didn't know you got a promotion.
If you try hard like he does, you might get one too.
Yeah, I mean, no kings, but lords are okay. The occasional lord.
There you go, that's right. I'm down with the Mill Kings, but I'm still Lord Nice.
So let's catch people up on your trajectory through life. You spent a lot of your professional career at Caltech over in Pasadena, and now you joined us back on the East Coast in Baltimore at the Johns Hopkins University. And I've got you as the Homeward Professor of Natural Philosophy. Thank you.
That's right. There aren't that many of those. I'm basically the only one, so it's nice. Right.
This is a very retro title.
It is. Okay.
I think Newton had a title of natural philosophy. Right. Before the word physics was a thing. Yeah. Yeah. And you're one of my favorite people out there because not only do you bring science to the public, which is something we care deeply about here at StarTalk, but you have, for me, the best combination of astrophysics fluency. Right. Physics fluency. Right. And philosophy fluency. Right.
What insights does Sean Carroll provide about the theory of everything?
You put all that together and there's no boring conversation you will ever have ever.
True. But we're going to try to change that today.
I'm going to take this as a challenge. Yeah, I bet I can do it.
So, Sean, you had a couple of books recently. I mean, you're always out there, you know, talking physics smack with an interested public. You have two in a row here, Space, Time, and Motion. That's what's left after that, right? That's a lot, yeah. That's pretty much everything, right? But no, not for Sean Carroll. He's got quanta and fields. Oh, wow, look at that.
Now it is everything. Space, time, and motion, and then quanta and fields. What's left?
What's left will be volume three, which is complexity and emergence. That's what I'm nearly done with writing right now. So it's a whole three-part series called The Biggest Ideas in the Universe, yeah.
That's definitely what that is. That is. For sure. For sure. You know, fields is a thing that if I didn't study physics, I'd still think they were kind of imaginary. Go back to Faraday, right, who says, well, there's magnetism there, but there's a field. Well, can I see it? No. But like the iron filings can see it. but I can't.
How do fields play a role in our understanding of physics?
Right. Okay. But if you take away the iron froth, is it still there? Yeah. And so just to, what did it take to get everybody comfortable with the idea of a field?
That's a great question because it wasn't easy. It took a while. You know, Isaac Newton worried about the fact that he didn't know about the concept of fields. He said that there was a gravitational force between the sun and the earth, and it depends on the distance, you know, the inverse square law, the bigger the distance, the less the force. But he didn't know how it got there. How does the earth know where the sun is, how far away it is, how massive it is? And he said, you know, this is over my pay grade. I'm going to leave this for future generations to decide, which is not the kind of thing that Isaac Newton said very often. So it wasn't until the 1800s.
