Challenging the Status Quo in Physics

Physicist Sabine Hossenfelder talks about her book Lost in Math with EconTalk host Russ Roberts. Hossenfelder argues that the latest theories in physics have failed to find empirical confirmation. Particles that were predicted to be discovered by the mathematics have failed to show up. Whether or not there is a multiverse has no observable consequences. Hossenfelder argues that physicists have become overly enamored with the elegance and aesthetics of their theories and that using beauty to evaluate a model is unscientific. The conversation includes a discussion of similar challenges in economics.
