String Theory Can’t FAIL This Test!

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.
