Episode notes

There are physics-based reasons why people like string theory when it comes to quantum gravity. String theory doesn't really care if you have new particles at the LHC, he says. "It absolutely has not made direct connection with observation" The other options on the table 'are for good reason, just not as attractive'

Physics is in crisis, what else is new? That's what we hear in certain corners, anyway, usually pointed at "fundamental" physics of particles and fields. (Condensed matter and biophysics etc. are just fine.) In this solo podcast I ruminate on the unusual situation fundamental physics finds itself in, where we have a theoretical understanding that fits almost all the data, but which nobody believes to be the final answer. I talk about how we got here, and argue that it's not really a "crisis" in any real sense. But there are ways I think the academic community could handle the problem better, especially by making more space for respectable but minority approaches to deep puzzles.
