Experimental evidence for any current Theory of Everything is, at best, inconclusive. This is perhaps the greatest fundamental challenge facing physics. That lack of progress has opened up a sea of controversy. In this thought-provoking episode recorded in 2020, I joined forces with Matt O’Dowd to debate some of the brightest minds in theoretical physics on the complexities surrounding the quest for a Theory of Everything. We were joined by Eric Weinstein, Sabine Hossenfelder, and Lee Smolin, We discussed the historical context and current challenges of unifying quantum mechanics with gravity, and the need for fresh perspectives and a broader range of approaches.
