Previously on Thirty Minute Thesis I've explored alternatives to string theory, such as Loop Quantum Gravity. But I realized I hadn't yet explored the basics of string theory itself. So in today's video I ask: "What would It take for String Theory to move beyond the realm of pure math, Into verifiable territory"? Is the fact that many 'discoveries' in string theory revolve around the math of theory itself or already disproven facts about our universe -- such as the fact that AdS/CFT correspondence relies on a negative cosmological constant, in contrast to the observed positive cosmological constant -- already fatal to this once-most-promising of all theories? Or could it be salvaged and, if so, how? Do we need new predictions, or would even a retrodiction suffice? This episode of Thirty Minute Thesis explores the experimental minimum -- the very basics that any purported theory of everything should aspire to achieve. We discuss the basics of the theory as delightfully explicated by Ed Witten in Physics Today and compare it to other approaches, such as Loop Quantum Gravity and more. Welcome to another episode of Thirty Minute Thesis -- a solo deep-dive into a fascinating topic in cosmology, physics, or science itself. Today's video explains what String Theory must do in order to prevail as a candidate Theory of Everything.

? Win your own meteorite by joining my mailing list https://briankeating.com/list ? Is climate science being politicized? Are facts being misrepresented and distorted to fit a certain narrative? Are climate scientists trying to dictate policy instead of investigating the actual truth? And what does it mean to be accused of being a global warming denier? Here today to discuss this controversial topic with me is no other than Steven Koonin! Steven is a renowned theoretical physicist and has recently been working on urban studies and government policies. He has also published a very provocative book, Unsettled: What Climate Science Tells Us, What It Doesn't, and Why It Matters. The book caused a lot of controversy as it challenged the dominant narrative on global warming, and today, he is here to state his case! Tune in.
