Summary
Is string theory the one true “theory of everything?” Some physicists swear it’s a fundamental ingredient of nature. Others wish it would just go away. On this episode of The Quanta Podcast, host Samir Patel speaks with columnist Natalie Wolchover about the mathematical developments that are keeping the theory relevant — much to the chagrin of its rather vocal critics. This topic was covered in a recent column for Quanta Magazine.
Each week on The Quanta Podcast, Quanta Magazine editor in chief Samir Patel speaks with the people behind the award-winning publication to navigate through some of the most important and mind-expanding questions in science and math.
This episode's audio coda is a clip from a 2024 live show of Alchemical String Theory (AST), a collective of avant-garde string artists from Atlanta's Improvisational Underground, performing a round at the Red Light Cafe in Atlanta.

| 0:00.0 | String theory remains a leading candidate for the long-sought theory of everything, |
| 0:10.0 | one that unites classical and quantum physics in a tidy, elegant, mathematical package. |
| 0:16.0 | But nearly six decades after it was first proposed, it's still about as controversial as theoretical physics |
| 0:21.7 | gets, with vocal proponents and critics and a whole bunch of physicists just trying to navigate |
| 0:27.6 | the swamp land in between. As a theory, though, it hasn't been stagnant, and in fact, a few |
| 0:34.6 | recent papers continue this tradition it has of having surprising, |
| 0:41.2 | almost miraculous mathematical powers to make things make sense. |
| 0:45.8 | But does it make any sense that is? |
| 0:59.5 | Welcome to the Quanta podcast where we explore the frontiers of fundamental science and math. |
| 1:02.4 | I'm Samir Patel, editor-in-chief of Quantum Magazine. |
| 1:12.7 | Our regular columnist Natalie Walschover has been covering physics, including string theory, for us for more than a decade. So it's natural that she'd be our guide for navigating this quagmire. She's here with us today to talk about her |
| 1:17.5 | latest essay, Our Strings Still Our Best Hope for a Theory of Everything. Welcome back to the show, Natalie. |
| 1:23.5 | Nice to be here, Samir. Okay, so Natalie, what's the big idea? |
| 1:29.0 | The big idea is really this disconnect that I think exists between the way string theory is talked about for the general public and the voices that are loudest. |
| 1:39.7 | The message people get is that this is kind of a dead theory and maybe even that people who are |
| 1:47.3 | still studying it have this false hope, but that actually it's this dead end. So a disconnect |
| 1:54.8 | between that and what I hear from theorist I talk to, which is that basically people think, yeah, it could be right. |
| 2:02.6 | And not only that, but there is a huge community that's still pursuing it and thinks it really is |
| 2:08.4 | still the most promising kind of theory of everything that we have as a candidate. |
| 2:12.4 | So I wanted to try to understand why that is the view you come to when you know more about this. And then, |
| 2:21.3 | you know, in the course of reporting on this, I also am aware of this new approach to the |
| 2:25.8 | subject that's developed over the past few years that's actually adding more life and more |
