Why String Theory is Wrong
Summary
This episode explores the tension between the mathematical beauty of string theory and its lack of empirical evidence, tracing its origins from Kaluza-Klein theory to the unification of five superstring versions into M-theory. The discussion highlights how dualities revealed these theories as different perspectives of a single framework, yet the existence of a vast "string landscape" of possible geometries prevents testable predictions. The episode concludes by addressing listener questions on mirror universes, CPT symmetry, and the chirality of DNA.
