Episode notes

Dark matter doesn't participate in this bouncing process. It's almost as if the odd numbered peaks are somehow being boosted, or the even numbered peaks are suppressed compared to what you might naively expect. This is a prediction made ahead of time and the dark matter prediction came out smack on what you expect. Can you do this with modified gravity? Could you do this like you do the spiral galaxies? Can you explain it away?

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.
